The price of gas may go up or down, but it's always a major expense for most drivers. The average American driver spends about $3,000 per year on gas, according to the American Automobile Association. Some of the practical ways to reduce fuel costs are listed below.

Use public transportation

Walking or biking does not consume fuel, and as such does not accumulate fuel cost. In most cases, public transport alternatives to cars such as buses, trains, and trolleys are viable options of reducing fuel costs. Due to the communal nature of ride sharing, the fuel costs of operating public transport are generally less than the fuel costs associated with each individual operating their own vehicle. In some places, public transport is free. Considering the costs associated with owning or renting a car creates even more incentive to use other modes of transportation.

Also known as car sharing, carpooling is the arrangement between two or more people to travel to a shared destination in a single vehicle. Although a heavier car consumes slightly more fuel, it is usually much more efficient than two people driving separate cars towards the same destination.

Use a more fuel efficient vehicle

Driving a smaller car makes a great difference – the fuel cost is about half for a small sedan than for a very large SUV. Similarly, drive with a less powerful engine than you need. Don't pay for an eight-cylinder engine when four cylinders work just fine. Unless you're hauling heavy loads on a routine basis, the extra cost of a bigger engine results in more money spent on gasoline.

Tune the engine

A properly tuned engine maximizes power and can greatly enhance fuel efficiency. But tuning the car engine is often done to increase horsepower – that's not the way to save on fuel. Make sure the tuner gets the message.

Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent – this amount will vary depending on the nature of the repair.

Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Placing ornaments and ground effects, aerodynamics kits, and airfoils, such as deck-lid spoilers, may make you feel good, but they also increase the car's drag and make it require more fuel. Such accessories offer no real handling enhancements, although they may look nice on your car. Also, place signs or cargo on the roof so that the object angles forward. This will reduce the frontal area of the object, and it will cause less drag, and cause you to use less fuel.

Adjust tires

Make sure the tires are inflated to the right levels. Properly inflated tires can reduce fuel consumption by up to 3 percent. Your tires also lose about 1 PSI per month, and when the tires are cold (e.g., in the winter), their pressure will decrease due to the thermal contraction of the air. It is recommended to check tires at least monthly, preferably weekly. Having properly inflated tires will also help you avoid uneven wear on the tread.

Gas stations don't always have accurate equipment for this purpose. Sometimes gas stations use automatic air compressors that stop at a pre-determined level. To make sure you inflate to the right level, double-check pressure with your own gauge.

Recommended inflation pressures are for cold tires; put about 3 PSI more in if the tires have been driven on a while. Inflate to the pressure recommended by the car manufacturer, not to the level stamped on the tire.

Use the correct motor oil

Gas mileage will improve by 1 percent to 2 percent if you use the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can reduce your gas mileage by a considerable amount. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1 percent to 2 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.

Plan trips carefully

There is no more obvious way to save gas than to drive a shorter distance.

Plan your route carefully. With today's GPS route planners, it's easy to calculate a straight route with the fewest stops and diversions. It is also possible to judge which route will have the least traffic. Take highways instead of local routes or city streets when possible – the steady speed maximizes fuel efficiency.

When driving in a city, try to park in a central location, and then walk from one appointment to another, or take public transportation. Ragged stop-and-go city driving is terrible for your gas mileage. This also saves the high level of gas used in parking and pulling out in a parking lot.

Factors that determine the fuel price

Government intervention.

Governments may intervene in gasoline (referred to as petrol in some parts of the world) markets by taxation, which may raise prices for consumers within or outside the governmental territory. Similarly, certain industries may receive financial support from the government to promote commercial enterprise (a subsidy). Generally, subsidized products or services can be sold at lower prices.

Financial markets

The global oil price fluctuates constantly. The key crudes quoted are Brent and West Texas Intermediate (WTI) in the unit of US$ per barrel. The retail fuel price is closely related to the global oil price fluctuation.

Political elements such as structure, regime, personnel, and events can all affect the cost of fuel. For instance, a change in leadership from a leader who doesn't believe in climate change to one who does may result in changes to the cost of fuel for consumers based on different policies, such as choosing not to subsidize fuel. Political relationships between countries are also a factor; nations can go to war over resources, or form alliances in order to trade, both of which can affect the cost of fuel.

Geographic area

Certain geographical areas or countries in the world have an abundance of oil, while others do not have a single drop. Regional consumers within close proximity of high supplies of oil are more likely to have lower costs of fuel due to ease of access. Areas without their own supply of oil that are isolated from the rest of the world (such as islands in the Pacific) can find fuel to be relatively expensive.

Natural disaster or weather

Earthquakes, tsunamis, hurricanes, major floods, and other such nature-related phenomena can affect the production, manufacturing, and logistics of gasoline, which can possibly affect the price of fuel. For instance, a snowstorm may close certain roads, disallowing the transportation of the resource and driving up fuel costs in these areas. Hurricanes or earthquakes can damage oil refineries, abruptly halting production, which can also eventually increase fuel costs.

    Fuel Needed & Fuel Cost Calculations

In order to calculate the amount of fuel for a given trip using our fuel cost calculator or otherwise, you need to know the total distance you will be covering and the expected average fuel consumption of your vehicle. It works the same way for cars, trucks, buses, vans, SUVs, and even boats and planes. If you also want to calculate the fuel cost of a trip, then you need to know the price per gallon or price per liter at which you can by.

Our calculator supports entering distances in miles and kilometers. In terms of fuel consumption, it is very versatile as it accepts: miles per gallon, gallons per 100 miles, kilometers per liter and liters per 100 kilometers. In the US, miles per gallon and kilometers per liter would more frequently used, while in most of Europe the preferred metric would be liters to travel 100 km and gallons to cover 100 miles. The result in terms of fuel amount is in gallons or liters, and for fuel cost is in the currency you entered it in (you can simply ignore the currency sign, e.g. $ (USD)).

Make sure to account for the variation in fuel consumption when driving within city limits and on highways - usually the consumption is higher in the former case. Always fill your tank with more fuel than you anticipate you would need, especially during winter or when driving through desolate areas or when extreme weather conditions are expected.

    Formula for fuel amount

If you are using mpg (miles per gallon), then the formula for calculating the total amount of gas needed is:

Fuel = Distance / Consumption mpg

For example, if the distance is 500 miles and consumption is 20 miles per gallon, then the fuel you will need for the entire distance is 500 / 20 = 25 gallons.

If you are using gallons per 100 mi to measure consumption, then the formula for calculating the amount of fuel needed is:

Fuel = Distance / 100 x Consumption per 100 mi

For example, if the distance is 300 miles and the consumption is 5 gallons per 100 miles, you will need 300 / 100 x 5 = 15 gallons of gas.

Both formulas are applicable for metric units - km and liters, just make sure you do not mix metric units. Using an online fuel calculator will make sure you do not commit that mistake.

    How to improve fuel economy?

Don't like the numbers you see when you use our tool? If you wonder how you can improve the fuel efficiency of your vehicle so you can cover more miles (or kilometers) with less fuel, we have some tips that can result in significant savings, especially when applied consistently over time. Here is our list of 10 fuel efficiency tips :

• Drive sensibly - If you drive aggressively - too fast compared to other cars, constantly overtaking other vehicles, and rapid acceleration followed by braking, only to accelerate again wastes a lot of gas. By some estimates, quick starts and hard stops can increase fuel consumption by more than 30% ! This is why this is number one in our fuel efficiency list.
• Observe the speed limit - Different vehicles have optimal fuel economy at different velocities, but one way to increase gas mileage is to avoid driving at higher speeds. A small reduction of your average speed , say from 70 mph to 60 mph (equivalently: from 115 km/h to 100 km/h) can help you save 10 to 20% due to lower fuel consumption.
• Follow the leader - drive at about the speed of the vehicle in front of you, if they are following the first 2 tips above. This will make sure you need to accelerate and decelerate as little as possible. If possible, overtake drivers who do not follow them, as it will make it very hard for you to do so. This will result in smaller numbers from our fuel cost calculator.
• Check your tires - make sure your tire pressure is at optimal levels as indicated in the owner's manual provided by the auto manufacturer. If the pressure is too low your mileage will decrease significantly, not to mention that the car may become dangerous to drive.
• Smart routing - make sure you take optimal paths to reach your desired destination. Learn the different modes of route selection your GPS employs - the shortest is not always the fastest and idling stuck in traffic will waste fuel. Use services such as Google Maps to check for traffic congestions on the planned route. Using a route you know well can also help improve fuel efficiency, since you will know in advance where it makes sense to increase speed and where it does not, because of a traffic light just ahead.
• Air conditioning - turning it off will most likely improve your fuel efficiency by 10-15%, and will result in you having more power to accelerate quicker when needed. If it is necessary, make sure you do not set it to unreasonably low or high levels. Air temperature in the range between 64°F - 75°F (18°C - 24°C) is comfortable for most people. Due to the law of thermodynamics, each subsequent degree of heating or cooling requires progressively more energy to accomplish and maintain.
• Remove excess weight - make sure you remove any unneeded heavy items you have in your trunk. One of the untold benefits of losing weight is that your car will be a bit more efficient as well.
• Turn cruise control ON - when on a highway, make sure to use your cruise control option. By keeping your speed constant, it will most likely save gas and result in lower fuel costs.
• Avoid idling - idling means 0 miles per gallon and the larger the car engine, the more gas is wasted when idling. Avoid excessive idling, when possible, in line with point #5 above to keep fuel costs low.
• Maintain your vehicle - a well-maintained car, truck, van, SUV, etc. will operate at greater efficiency. Exact fuel savings are hard to calculate, as it will depend on the type of maintenance work your vehicle needs. However, good maintenance is sure to lead to fuel savings and smaller cost numbers coming out of our calculator.

All the above advice is fine, but what do you do if you have been following the above advice, yet our tool still shows you numbers that are so high you want to cry? Well, it is most likely time for a new car, or it could be just the fuel price fluctuations over which, unfortunately, neither you nor we have much influence, individually. Fuel prices in most places contain license fees and other state or local government taxes, in some places reaching as much as 50% of the final price. Financial market fluctuations, natural disasters or extreme weather, crisis, as well the geographical area you are in and the local fuel suppliers all influence the price of gas. All you can do is try to observe them and predict when you can get a more decent price.

Gas Calculator

How much gas will i use, splitting the gas cost, related topics, cost of gas, gas prices and taxes, gas price history, gas price increase, gas price today, fuel economy, best fuel economy cars, cost of gas for trip.

This gas calculator is a handy tool for every driver who, when planning a trip, asks how much gas will I use? We prepared the gas estimator to help you find out how much fuel you will use on a car trip and how much it will cost you.

Our gas cost calculator is versatile and offers more then other web-based fuel cost calculators (e.g. splitting the gas cost). All you need is to enter the driving distance and the average fuel economy of your car - then, all the math is done automatically! In fact, your biggest concern will be how much gas costs at your nearest gas station.

That's not all, though. In the corresponding article, you can find information about gas price today, gas price history, and gas price increase. Also, check out the best fuel economy cars and how to do eco-drive properly. Finally, a user-friendly tutorial will ensure you're using the gas calculator properly.

Our gas estimator operates on a very simple premise:

• Determine the distance you are about to travel. Let's say 295 km .
• Find out what's your fuel economy. Let's use 8 l/100 km .
• To work out how much fuel you will use in total, divide your distance by 100 (because we are looking at the fuel use every 100 km), so: 295 / 100 = 2.95 and then multiply it by your combustion, so by 8: 2.95 × 8 = 23.6 . Now you know that you will use 23.6 liters of fuel.

If we want to take this one step further and find out how much this trip will cost us:

• Determine the price of the fuel. Let's say 1.6 €/L .
• To find out the total price, multiply the total amount of fuel you will use by its price, so: 23.6 l × 1.6 €/L = €37.76 .
• Now you know how to calculate the fuel use and its cost on your own, or you could use our gas calculator to make it so much easier and faster!

We finally know the answer to the question: how much gas will I use? However, we often travel with other passengers, so there is no need to pay for gas only by ourselves, we can split the cost among all passengers instead. All those calculations can be working awkward, so to spare you time and effort, our gas calculator can do it for you:

• Find out the total fuel cost. Let's use the example above of €37.76 .
• Determine how many people are there. Let's say 4 .
• Divide the total price by the number of people to work out each person's share: €37.76 / 4 = €9.44 or let our gas estimator do it for you!

There is occasionally a situation when you need to convert liters into gallons, be it US gallons or UK gallons. Let's be honest, no one has ever learned to do it by heart, so we always seek out help, mostly online. Our gas calculator has the option of not only choosing whether you want to count liters or gallons but also what is the distance unit - kilometers, miles, etc. However, we encourage you to use our mpg converter for converting between liters and gallons.

You might also find yourself reluctant to drive everywhere. If you're planning to spend some time in a different city, for instance, it might be more economical to use public transport! Take a look at our ticket optimizer to choose the cheapest combination of tickets for your stay.

Every car user spends money on gas. It is one of the most noticeable vehicle-related expenses. You can drive a car that has old tires, but without a full fuel tank, you will not travel far. So, it is evident that we quickly notice any increase in fuel price. According to the American Automobile Association (AAA) , the average driver spends $3000 on fuel annually.

Gasoline prices are not determined just by the price of crude oil. Let's take a closer look at it. According to the Energy Information Administration (EIA) , the average price of a gallon of regular gas in May 2014 was about $3.67. For the week of June 23, it would set you back $3.70. A French driver would have paid around $7.83, a British one $8.94. In Norway, which produces 1.8 million barrels of oil per day, a gallon of gas reached $9.90.

According to the EIA data from May 2014, the costs of producing crude oil account for only 65% of the average gas price. The next 12% are taxes (federal, state, and local), and another 11% for distribution and marketing. Refining accounts for about 13% of the gasoline price.

A big part of the gas price is taxes. The U.S. federal government established an 18.4 cents tax on gasoline and 24.4 cents on diesel. Without taxes, a gallon of gasoline is more expensive in the USA than in the U.K. ($3.18) and France ($3.37). There are also local and state taxes to consider. According to the Tax Foundation , if you are buying gas in New York State, you would pay the highest taxes in America (50.6 cents per gallon in 2013). The lowest taxes are in Alaska, where most of America's oil comes from - they are 8 cents.

Below you will find the retail price of regular gasoline in the United States from 1990 to 2017 (in U.S. dollars per gallon) . Check the fluctuations of a gas price over the last seventeen years.

Gas prices are not stable and they tend to fluctuate over time. These variations may be driven by many different factors e.g. consumer fears over refining capacity. There are also economic factors, for example, non-stable geopolitical situation (especially near oil-producing nations) or the risk of an oil-supply interruption.

To illustrate this principle, let's go back in time to 2005 when Hurricane Katrina hit much of the refining capacity along the Gulf Coast. Many refineries had to be closed, which caused a decrease in oil supply and, automatically, a high increase in gas prices. That year has begun with the average monthly gas price at $2.27 and finished at $2.76 but within the general upward trend. In September, there was a peak up to $3.47 due to fears about the gasoline supply - this is the first time in history when gas prices exceeded the $3 threshold.

Even though the supply has met the demand shortly after, gasoline suppliers weren't inclined to lower the prices, as their customers got used to new prices. As a result, the price of gasoline has been kept high since the hurricane.

According to the Energy Information Administration , USA produces about 12% of the world's oil, which amounts to 2.7 billion barrels per day . That makes the United States one of the major oil-producing countries, up there with the likes of Saudi Arabia and Russia. However, the U.S. is also one of the biggest consumers of gasoline on a per capita basis, with approximately 1.22 gallons of gas per person daily. Gasoline is often regarded as a key driver of a country's economy. It is the main fuel used in passenger vehicles and the automotive fleets of small and large businesses.

Let's take a look at a worldwide gasoline prices comparison (in U.S. dollars per gallon). The data comes from April 16th, 2018. Fuel prices vary from a few cents to over 7 dollars per gallon. Gas price in the U.S. placed at the level of $2.99, while in Germany it was considerably higher - $6.43. We can observe that generally, gas prices in Europe are much higher than in America. Norway is the infamous world leader in gas prices at $7.82 per gallon. This is over 2.6 times more than in the USA and... 261 times more than in Venezuela ($0.03).

We all wish we didn't have to spend so much on gas, and would like to keep that money in our wallets instead. Check out the tips below if you want to save more money while fueling your car:

Check prices online - nowadays, there are many websites that provide daily updated gas prices in your neighborhood. Spending a little bit of time on an Internet check will allow you to plan a route for a gas stop at the station with the best prices. Try to do it for a month or two, and you will notice which stations consistently offer lower prices, and which tend to raise them.

Stay away from the highway - the stations which are located close to big roads are often the easiest to reach and prompt you their good quality coffee and meals. Keep in mind that probably you will pay more (sometimes much more) just because of the good location of the business.

Small, private stations - are a good alternative. Owners are not affiliated with big brands which take some of the income because of brand recognition. The quality of gas has to be compliant with standards, so you shouldn't be concerned about it.

Plan your purchase - try to avoid the situation when you will be forced to fill up by the fuel indicator on your dashboard. You would probably have to stop at the nearest gas station; hopefully not one close to the highway.

Join the club partnership - most gas companies offer club partnerships. Being a club member enables you to recoup some money if you refuel at their gas stations regularly. Usually, you collect points when filling up, and then you can exchange them for discounts or gifts.

Because of rising fuel prices more and more motorists are conscious of getting the maximum efficiency from their cars. Eco-driving is a way of driving that reduces fuel consumption, gas emissions, and accident rates. This term is the synonym for driving in a smart, smooth, and safe way that leads to an average fuel savings of 5-10% . Keep in mind - good driving is eco-driving .

If you are interested, follow the rules below:

• Anticipate the traffic flow : Look ahead on the road as far as you can and try to anticipate the flow of traffic. Maintain a larger safety distance from other cars to increase your scope of the traffic. Use this knowledge to get the most out of your vehicle's momentum (in gear or neutral), accelerating and braking smoothly.

🙋 Learn how to estimate traffic flow in the traffic density calculator .

Maintain a steady speed at low RPM : Drive gently, using the highest possible gear at low RPM. Avoid driving at excessive speeds. Try to keep the speed steady and avoid unnecessary braking and acceleration.

Shift up early : Change to a higher gear at around 2000 RPM.

Check tires pressures frequently : Ensure your tires are properly inflated. Low tire pressure is a safety risk and a waste of fuel.

Avoid dead weight and aerodynamic drag : Remove heavy objects that you don't use from your car (for sure you have some). Also, keep windows closed while driving on the motorway - it helps to improve the fuel economy.

Use air-conditioning sparingly : Using the AC unnecessarily is a waste of money, because keeping it on increases fuel consumption.

Share your car : One of the best ideas to save money. Just one additional passenger would reduce your trip expenses by 50%.

“New vehicles offer the latest designs, cutting-edge technologies, and warranties that offer peace of mind, but, car owners that like to change vehicles frequently should be thinking about the resale value – not just the purchase price – when choosing their next ride.” John Nielsen, American Automobile Association's (AAA) managing director of Automotive Engineering and Repair.

The latest annual AAA’s analysis shows a shift in consumers' preferences. We can observe an increased appetite for SUVs cars and pickup trucks and a decreased demand for sedans.

It results in a higher car depreciation costs (up to 13% in comparison to last year) of these ex-popular cars. Electric and hybrid vehicles have also increased in their popularity - 20 percent of Americans (15% in the previous year) say they are likely to buy an electric car as their next vehicle. It is not surprising - driving "green" cars is going to be more and more affordable. It is because of much lower fuel and maintenance charges.

Research conducted by AAA shows the average cost of owning and operating a new vehicle in 2018. The study is based on the cost of fuel, maintenance, repairs, insurance, and taxes. 45 top-selling 2018 model year cars were taken into account across nine categories. The databases on 15,000 miles driven annually.

New cars are attractive to buyers because of the newest technology and electronics inside, various accessories, and a multitude of configuration options. However, they are not the best economical choice for some customers. For those who look for alternatives to new car ownership or ways to minimize operating costs should take a look at the tips below:

Buy a pre-owned car - slightly used vehicle in good condition is an affordable choice. Ownership costs are significantly lower, and the vehicle can still be safe, reliable, and perfect for driving.

Fuel responsibly - avoid wasting money on premium grade gasoline (unless your vehicle requires it) and on tanking up at expensive gas stations (e.g., those near highways).

Take care of your car - in general, spending money on routine maintenance will save you money.

Drive eco - when gas prices rise, small changes in your driving style could make a significant difference to your wallet.

Cars with great gas mileage used to have a reputation for being underpowered and small. However, the latest technologies, from plug-in hybrids to weight-saving measures and new solutions applied to engine construction, helped to change it. Nowadays, it means that nearly any kind of vehicle can be efficient without compromising space, comfort, or fun. Take a look at the top 15 best fuel economy cars:

• Toyota Prius Prime (2018)
• Hyundai Ioniq PHEV (2018)
• Honda Clarity PHEV (2018)
• Chevrolet Volt (2018)
• Kia Niro PHEV (2018)
• Kia Optima PHEV (2018)

You are planning a trip, and you are wondering how to get there. Usually, if the distance is not too big, traveling by car is fast and comfortable. Moreover, it is often cheaper than flying or even taking a train. But is it always? Finding the answer involves the current price of gasoline, your car's fuel efficiency, the distance, and some other road fees.

While planning a trip by car, first you should find out what your car fuel economy is (You can do that with our mpg calculator .). Then, knowing the trip distance, you can use the fuel cost calculator and easily find if is it affordable for you to use a car for the trip. Remember, you can easily reduce the costs of gas by finding cheap gas stations on the way and by taking more friends with you, who can chip in for the fuel.

Why do gas prices go up?

Gas prices may go up for a number of reasons:

• Restricted supply of oil;
• Increased taxes; and
• The seller wished to increase their profit margins.

Does cruise control save gas?

Yes , cruise control saves gas, but only on flat roads. This is because it prevents unnecessary acceleration and deceleration , which can eat more fuel by the sudden shifts in the engine's demands. However, when using cruise control to climb hills, it cannot anticipate when you'll reach the top of the hill and so will keep the gas on for longer than you would.

How much will my drive cost me?

To find out how much your drive will cost, follow these steps:

• Find the distance you have to travel and the fuel efficiency of your vehicle.
• Multiply these two figures together. Ensure that the two distance units are the same. This result will give you the total fuel used.
• Multiply the total fuel burned by the price of fuel. The two units of volume need to be the same.
• The result is the total cost of your drive.

Trip Gas Price Calculator

About trip gas price calculator (formula).

The Trip Gas Price Calculator is a tool used to estimate the total cost of fuel for a trip based on the distance traveled, vehicle’s fuel efficiency, and current gas price per gallon or liter. It aids in budgeting and planning for travel expenses. The formula for calculating the trip gas price involves considering the distance, fuel efficiency, and gas price.

Formula for calculating trip gas price:

Trip Gas Price = (Distance / Fuel Efficiency) * Gas Price

In this formula, “Distance” represents the total distance to be traveled in miles or kilometers, “Fuel Efficiency” represents the vehicle’s fuel efficiency in miles per gallon (MPG) or kilometers per liter (KPL), and “Gas Price” represents the cost of gas per gallon or liter.

For example, let’s say the total distance of the trip is 300 miles, the vehicle’s fuel efficiency is 30 MPG, and the gas price is $3.50 per gallon. The trip gas price would be calculated as follows:

Trip Gas Price = (300 miles / 30 MPG) * $3.50 per gallon = 10 gallons * $3.50 per gallon = $35.00

This means that the total cost of fuel for the 300-mile trip would be $35.00.

The Trip Gas Price Calculator simplifies the process of estimating fuel expenses for a trip, aiding travelers in budgeting and planning for their journeys. By inputting the distance, fuel efficiency, and gas price, the calculator quickly provides the trip gas price, allowing travelers to have a clear view of their fuel costs and make informed decisions to manage travel expenses effectively.

Gas Cost Calculator

This free gasoline cost calculator evaluates the fuel cost of a journey using several units of measurement depending on fuel efficiency, distance, and gas price.

Table of Contents

Use public transit instead of driving yourself, invest in a car that is more environmentally friendly, tune-up the engine, check tires, use the proper engine oil, make sure you plan your journey well, involvement of the state, capital markets, geographical location, disasters caused by natural causes, such as bad weather.

This calculator can forecast gasoline costs based on journey distance, vehicle fuel economy, and gas prices in different units.

The cost of gasoline can fluctuate, but it remains a significant expense for most drivers. According to the American Automobile Association, an American motorist’s average annual gasoline expenditure is $3,000. The following is a list of practical techniques to cut gasoline expenditures.

Free public transportation is available in some areas. Most of the time, avoiding a car and taking public transportation like buses, trains, or trolleys can save money on gas.

The gasoline costs of running public transit are often lower than the fuel expenses involved with everybody driving their vehicle because of the communal character of ride-sharing. Considering the price of owning or renting a car is even more of an incentive to use other forms of transportation.

Carpooling is a way for several people to arrange to share a vehicle for a trip to a specific location. It is usually far more efficient than two individuals driving different automobiles to the same place.

A smaller automobile makes a massive difference in gasoline costs; a compact sedan costs approximately half as much as a big SUV. Don’t waste your money on an eight-cylinder machine if you only need four. Even if you’re often transporting heavy loads, the additional expense of a larger engine translates into a higher gasoline bill.

A well-tuned engine optimizes power while also improving fuel efficiency significantly. You may achieve an average of 4% improvement in the gas economy by repairing a vehicle that is clearly out of tune or has failed an emissions test. You can achieve a 40 percent increase in mileage by fixing a maintenance issue, such as a defective oxygen sensor.

Regularly checking your tire pressure is essential for maintaining optimal vehicle performance and safety. Properly inflated tires can improve your vehicle's fuel efficiency by up to 3%. It's important to note that tires naturally lose about 1 PSI (pounds per square inch) per month, and tire pressure is further affected by temperature fluctuations — it tends to drop in colder conditions due to the air contracting.

To ensure accuracy, inspect your tire pressure when the tires are cold, at least once a month and ideally every week. This practice not only aids in fuel conservation but also contributes to even tread wear, prolonging the lifespan of your tires.

While many gas stations offer air compressors, their calibration can be inconsistent. After filling your tires, always confirm the pressure with a reliable tire gauge. Remember that the inflation levels specified by the manufacturer apply to cold tires. If you must adjust tire pressure after driving, the general rule is to add 3 PSI to compensate for the increase in temperature.

Avoid relying on the maximum pressure detailed on the tire sidewall; this number is not the recommended driving pressure but the maximum pressure the tire can hold. Always adhere to the vehicle manufacturer's recommended tire pressure settings for the best performance.

Use the manufacturer’s suggested motor oil, and you’ll get a 1 to 2 percent increase in gas mileage. Using 10W-30 motor oil in an engine built for 5W-30 will lower your gas mileage by a significant amount.

You can achieve a 1% to 2% decrease in the gas economy by using 5W-30 in an engine for 5W-20. The API performance mark shows that motor oil is “Energy Conserving” if it contains friction-reducing additives.

Driving a shorter distance is the most apparent strategy to conserve gas.

Make a detailed map of your trip. Today’s GPS route planners make it simple to determine the straightest path possible with the fewest detours. You may predict which route will be less congested by looking at traffic patterns. When workable, choose highways instead of city streets or local roads. The consistent pace of motorways helps maximize fuel economy.

Try to park conveniently and walk or use public transportation between appointments when driving in a city. Gas mileage suffers when you’re stuck in a city traffic jam. You’ll also save gasoline because you won’t have to park and pull out of a lot.

Factors influencing the price of fuel

Gasoline taxation may affect prices for customers both inside and outside of governmental jurisdictions. Similarly, the government may provide financial help to specific industries to encourage commercial activity (a subsidy). Subsidized goods and services are often sold at a lower cost.

The price of oil throughout the world is continually fluctuating. Brent and West Texas Intermediate (WTI) is the most commonly cited crude in US dollars per barrel. The variation in the global oil price has a significant impact on the retail price of gasoline.

Events, structures, regimes, and individuals impact gasoline prices. Nations can wage war over resources or create trade alliances, both of which affect the price of gasoline. Gasoline prices may be affected by a change of political leader who does not believe in climate change to one who does. The latter may be less inclined to subsidize or reduce the cost of fuel to consumers.

Oil is abundant in certain places of the earth, but there is none in others. Because of the ease of access, customers in areas with plentiful oil supply benefit from lower gasoline prices. Fuel can be prohibitively expensive for places without a reliable oil supply cut off from the rest of the world. Pacific Islands can be an example.

Natural disasters like earthquakes, tsunamis, hurricanes, and extensive floods can affect gasoline production, manufacturing, and logistics, affecting the fuel price.

Tropical storms and earthquakes can cause oil refineries to shut down, leading to higher gasoline prices. Due to heavy snowfall and other extreme weather conditions, highway closures can make transporting resources challenging and raise gasoline prices.

Travel Cost Calculator

Quick links, trip pricing calculator.

Travelmath provides an online cost calculator to help you determine the cost of driving between cities. You can use this data to figure out a budget for a road trip. The driving calculation is based on the average fuel efficiency of your vehicle, and you can change the gas mileage in mpg or L/100 km to match your exact make and model. Gas prices are automatically estimated based on current fluctuations, and again you can adjust these to fit your local gas station prices. Both U.S. and international units are available to make the calculations easier to use, and the output is given for both one-way and round trip travel routes.

Check the driving distance for your planned route, and see if the total driving time requires an overnight stay. If it's a long trip, you may want to research some hotels along the way . Or compare whether it's better to fly or drive to your destination.

With gas prices changing every day (and in every place), it can be difficult to know just how much your daily commute and other trips are costing you.

Fuel Trip Calculator: Calculate Your Fuel Trip Costs Instantly Back to video

Our fuel trip calculator can help! Using fuel efficiency data from Natural Resources Canada, the calculator can estimate how much you’re spending on gas each day — or how much you’ll spend on gas for your next road trip.

Save Money on Fuel Trips with a Top-Rated Fuel Trip Calculator

New: compare new and past models with the driving vehicle comparison tool ..

If you’re looking to cut down how much you spend on gas, Natural Resources has tips for more fuel-efficient driving:

• Accelerate gently

• Drive at a steady speed (50-80km per hour is the most efficient range for many vehicles)

• Coast to decelerate

• Avoid idling

• Avoid carrying unnecessary weight

• Limit the use of air conditioning and other powered accessories

• Limit all-wheel and four-wheel drive

Data for the calculator comes from Natural Resources Canada, which publishes fuel efficiency figures for most makes and models of cars sold in Canada. The calculator assumes a combination of city and highway driving for determining fuel efficiency, so costs will be higher if you drive primarily in a city, where fuel efficiency tends to be lower.
