As the price of fuels increases all the time, more and more drivers are aware of how much fuel their car needs. While the exact fuel consumption of your car changes based on your circumstances (city or highway, road conditions, tire pressure, etc.), it is actually very easy to find out the car's fuel consumption.
[ Edit ] Step
[ Edit ] Find Fuel Consumption
- Know that the equation for fuel consumption is "Miles Driven divided by Amount of gas divided by "A car's fuel consumption is a measure of miles driven per gallon of gas. If you know the distance you drove and how many liters fit in your tank, you can simply split the miles with the gas to get your "miles per gallon" or mpg.
- Your trip meter will say "0 miles."
- If you do not have a tachometer, register the number of miles on your car as "Start the lane." For example, if your car has 10,000 miles on it when you fill your tank, type "10,000."
- Record the miles on the trip meter just before you buy more gasoline. Before you start loading your car at the gas station, record the mileage on the odometer as "Final Mileage."
- If you do not have a travel meter, subtract "Start mileage" from your current mileage to find out how far you traveled. If your odometer now says, for example, 10 250, subtract 10,000. You drove 250 miles on that idea.
- Drive your car until the tank is almost empty. You can perform this calculation no matter how much gas is left in the tank, but the more gas you use, the more accurate your reading will be.
[19659009] Record the amount of gas you buy in liters. Fill your tank completely and note how many liters / liter you needed to fill the tank. This is you "Fuel Use."
- You need to refill your tank completely for this to work, otherwise you will not know how much gas your car used since your last tank.
- Share mileage by fuel consumption to see the car's fuel consumption. This tells you how many miles you drove per gallon of gasoline. For example, if you drove 335 miles before refueling and filled your car with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallons = 27.9 mpg).
- If you measured in kilometers and liters, you should instead divide fuel used by miles driven and multiply the result by 100 to get "liters per 100 kilometers".
- You have to start from an entire tank and go back to a full tank to know exactly how much gas your car consumed.
- Practice calculating an example. Terry's odometer reads 23,500 with a full tank. After driving for a few days he has to buy gasoline. The mile reads 23,889 and it takes 12.5 gallons to fill the tank. What was his fuel consumption?
- Fuel Consumption = (Final Mileage – Starting Mileage) / Fuel Usage
- Fuel Consumption = (23.889 mi – 23.500mi) / 12.5 gallons [19659009] Fuel Consumption = 38
- Fuel Consumption = 31.1 mpg
[ Edit ] Find Average Fuel Consumption
- Remember that fuel consumption changes based on your driving. For example, stopping and starting the car a lot uses a lot more gas than driving at a constant rate. That is why highway consumption is always less than city consumption.
- Cruise control can help you get better fuel consumption.
- Fuel consumption gets worse the faster you drive.
- Since AC uses gasoline, its use will reduce your fuel consumption. ^{ [1] }
- Record several tanks in a row to find your average fuel consumption. To get a more accurate picture of the car's fuel consumption, you need more information. By driving longer and averaging your fuel consumption, you eliminate "problems" in your data.
- For example, say that you calculated your fuel consumption one day when you were driving up a mountain. As climbing up takes more fuel, your fuel consumption looks much lower than it normally is.
- Set your trip meter to zero with a full tank. Set the odometer to zero and do not reset it after receiving a tank of gasoline. If you do not have a odometer, record how many miles are on your car with a full tank.
- Record how many liters of gasoline you buy each time you fill. To get a more accurate measure of fuel consumption, you need to know how much gas you use. Each time you fill, write the number of gallons you buy and save it.
- Normally runs for several weeks. Do not reset your trip meter while driving. Make sure you fill your car 3-4 times for a correct reading. Try to do this over a month of average driving, as large trips or unexpected traffic will change your fuel consumption.
- You do not need to fill your car all the way every time. As long as you register the number of liters you put in, you can calculate fuel consumption.
- Fill your tank completely after 2-3 weeks. When you are ready to calculate your fuel consumption, load your car and register the number of gallons you have added.
- Add the number of gallons you purchased. This represents the total gas used during this time period.
- If I bought three tanks of gas, 12 gallons, 3 gallons and 10 gallons, my total gas use would be 25 gallons.
- Divide the total mile by total gallons. Use your trip meter to see how many miles you traveled in total and then divide this by gallons to get your average fuel consumption. While this is the exact number of miles per gallon during your test period, it is a good estimate for your car's average fuel consumption.
- For example, if you used 25 liters of gas and drove 500 miles during that time, then your average fuel consumption would be 20 miles per gallon (500 miles / 25 gallons = 20 mpg).
- Know that your car advertised mileage is often overestimated. By law, car manufacturers must record the average fuel consumption for cars. But these are just estimates, and they are often high-level. ^{[2]} You can find your car's fuel consumption online through this US Department of Energy website, but to find the actual miles per gallon of the car you have to calculate it yourself.
- If your calculation differs drastically from the proposed average, you may need to bring your car to a mechanic.
[ Edit ] Minimize fuel consumption
- Avoid using the air conditioner. AC uses gasoline to cool your car, which means you have less gasoline to actually drive. Turn off the AC power or turn it off when the car is cool to make your car more efficient.
- Running alternating current at max can reduce your fuel economy by almost 25%. ^{ [3] }
- Drive at the speed limit. The faster you drive your car, the more fuel you will consume. This is not a small change either – every 5 miles per hour your drive is over 50 km / h, equivalent to paying $ 0.19 more for every gallon of gas. ^{ [4] }
- Drive defensively. It takes more energy to start moving a car and then moving it. This means that if you constantly tailor people, stop and start or try to pass, you use a lot more fuel than if you keep a steady pace.
- Try not to slow down or accelerate hard. Brake early instead of hitting the pedal. ^{ [5] }
- Use cruise control for long, flat stretches. Cruise control will keep your car at a consistent and consistent speed, avoiding the need to burn fuel unnecessarily with small accelerations and stops. ^{ [6] }
- Turn off the car in traffic. Idling, or leaving your car on when it is not moving, wastes gasoline without moving you anywhere. If possible, cut off the engine to save on valuable gasoline. ^{ [7] }
- Avoid roof load carriers. These greatly reduce the aerodynamics of your cars, slow down your car and make you use more fuel. In general, towing of trailers or loading of luggage space is a more fuel efficient alternative.
- Keep your tires well inflated. Under inflated tires can reduce the gas mileage by 0.3% if all four tires are low. With the help of free air pump at most gas stations, inflate the tires up to the PSI recommended in your instruction manual. ^{ [8] }
- Some cars list the correct tire pressure on a sticker in the driver's side door or glove compartment.
- Replace your air filter. This is one of the cheapest and easiest ways to boost your fuel efficiency. Make sure you buy the right filter for your car by bringing the make, model and year to your local car shop and asking for recommendations – each car needs a different filter.

[ Edit ] Tips [19659087] Note the published speed limit.
Do not raise and slow down irregularly, it wastes fuel, especially in large SUV / Sedan vehicles.
There is usually no point in turning off the car at a traffic light, as it usually only has to wait a maximum of 2 minutes if there is not much traffic. Only switch off the car if you are absolutely sure it is better to turn it off (eg waiting to pick up someone at the airport).
