With the cost of fuels going up all the time, more than and more than drivers are aware of how much fuel their machine needs. While the exact fuel consumption of your car changes based on your circumstances (urban center or highway, road conditions, tire pressure, etc.), finding out your car's fuel consumption is actually very easy.

i
Know that the equation for fuel consumption is "Miles Driven divided by Corporeality of Gas Used." A auto's fuel consumption is a measure of miles driven per gallon of gas. If yous know the altitude you drove and how many gallons fit in your tank, you tin can simply divide the miles by the gas to become your "miles per gallon," or mpg.
- Yous can perform the same calculation with kilometers and liters as well.
- The all-time time to record is correct afterward you fill your car with gas.
2
Reset the "trip odometer" after you fill upward your tank. Newer cars have a trip odometer that you can set to zero at any time. It is usually on the dashboard or center console, with a small-scale button y'all can concur to reset it to null. Ready it to zip when yous make full upwardly the auto and check information technology when you lot need to make full up again -- this is your mileage since you last bought gas.
- Your trip odometer will say "0 miles."
- If y'all don't have a trip odometer, record the number of miles on your car as "Starting Mileage." For example, if your car has 10,000 miles on it when you fill up your tank, write "10,000."

Record the miles on the trip odometer correct earlier you buy more gas. Before you showtime filling up your car at the gas station, tape the mileage on the odometer equally "Terminal Mileage."
- If you do not have a trip odometer, decrease your "Starting Mileage" from your current mileage to find out how far your traveled. If your odometer at present says x,250 for example, subtract x,000. You collection 250 miles on that tank of gas.
4

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 utilise the more accurate your reading volition exist.
five
Tape the amount of gas yous buy in gallons. Refill your tank completely and note how many gallons/liters you needed to fill up the tank support. This is you "Fuel Usage."
- You must refill your tank completely for this to work, otherwise you don't know how much gas your car used since your last tank.
6
Divide mileage by fuel usage to see your car's fuel consumption. This tells yous how many miles you drove per gallon of gas. For case, if you drove 335 miles before refueling, and you filled your car upward with 12 gallons of gas, your fuel consumption was 27.ix miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).
- If you measured in kilometers and liters, you should instead dissever fuel used by kilometers traveled and multiply the result by 100 to go "liters per 100 kilometers".
- Yous have to start from a total tank and return to a full tank to know exactly how much gas your auto consumed.

Practise calculating with an instance. Terry's odometer reads 23,500 with a full tank. After driving for a few days he needs to buy gas. The odometer reads 23,889, and it takes 12.five gallons to refill his tank. What was his fuel consumption?
- Fuel Consumption = (Concluding Mileage - Starting Mileage) / Fuel Usage
- Fuel Consumption = (23,889mi - 23,500mi) / 12.5 gallons
- Fuel Consumption = 389mi / 12.5 gallons
- Fuel Consumption = 31.1 mpg

Remember that fuel consumption changes based on your driving. For example, stopping and starting the automobile a lot uses much more gas than driving at a constant footstep. This is why highway consumption is ever less than metropolis consumption.
- Cruise control can assist yous get improve fuel consumption.
- Fuel consumption gets worse the faster you lot drive.
- Since AC uses gasoline, using information technology will diminish your fuel consumption.^[1]
two
Record multiple tanks of gas in a row to observe your average fuel consumption. To get a more accurate pic of your automobile's fuel consumption, you demand to take more data. By driving for longer and averaging your fuel consumption you eliminate "glitches" in your data.
- Say, for example, that you calculated your fuel consumption one day as you collection up into the mountains. Because climbing uphill takes more fuel, your fuel consumption would look much lower than it normally is.
three

Gear up your trip odometer to zero with a total tank of gas. Set your odometer to nix and don't reset it after you get a tank of gas. If you lot don't take an odometer, record how many miles are on your car with a total tank of gas.
4

Record how many gallons of gas y'all buy each fourth dimension you fill upward. To get a more accurate mensurate of fuel consumption, yous demand to know how much gas you are using. Each time you fill, write downwards the number of gallons you purchase and save it.
v
Drive for normally for several weeks. Do not reset your trip odometer as you drive. Make certain your make full upwardly your automobile iii-iv times for an authentic reading. Try to do this during a month of average driving, as big trips or unexpected traffic will modify your fuel consumption.
- You lot do not demand to fill your car all the way up each fourth dimension. As long equally yous record the number of gallons you put in you can calculate fuel consumption.
6

Fill up your tank fully afterwards 2-three weeks. When you are prepare to calculate your fuel consumption, tiptop your motorcar off and tape the number of gallons you lot put in.
7
Add upward the number of gallons you bought. This represents the total gas used over this period of fourth dimension.
- If I bought three tanks of gas, 12 gallons, iii gallons, and 10 gallons, then my total gas usage would be 25 gallons.
8
Divide total miles by total gallons. Use your trip odometer to see how many miles you lot traveled total, then split this by gallons to get your average fuel consumption. While this is the exact number of miles per gallon during your test catamenia, it is a adept estimate for your car's average fuel consumption.
- For example, if you used 25 gallons of gas, and drove 500 miles during that time, then your boilerplate fuel consumption would be 20 miles per gallon (500 miles / 25 gallons = 20 mpg).
9
Know that your machine's advertised mileage is frequently overestimated. Past constabulary, machine makers must post the average fuel consumption for cars. However, these are only estimates, and they are frequently on the high terminate.^[two] You tin wait up your car's fuel consumption online through this US Department of Energy website, simply to find your car'south bodily miles per gallon you'll accept to calculate information technology yourself.
- If your calculation is drastically dissimilar from the suggest boilerplate, you may need to bring your car to a mechanic.

Avoid using the air conditioner. The Ac uses gasoline to absurd your car, which means you lot have less gasoline to really bulldoze with. Turn down the AC or plough information technology off once the automobile is cool to brand your car more efficient.
- Running Air conditioning on max can decrease your fuel economy past about 25%.^[3]
2

Bulldoze at the speed limit. The faster yous bulldoze your auto the more fuel you volition eat. This is not a small modify, either -- every 5 miles per 60 minutes your drive over 50mph is the equivalent of paying $0.19 more than for each gallon of gas.^[4]
3
Bulldoze defensively. It takes more energy to beginning moving a motorcar and so to keep it moving. That ways if you lot are constantly tailgating people, stopping and starting, or trying to pass, yous're using far more fuel than if yous were keeping an even footstep.
- Endeavour non to brake or accelerate harshly. Brake early on instead of slamming on the pedal.^[5]
iv

Use cruise-control for long, flat stretches. Cruise control will keep your car at a consistent and fifty-fifty speed, which avoids burning upward fuel unnecessarily with small accelerations and stops.^[half-dozen]
5

Turn off your car in traffic. Idling, or leaving your car on when it isn't moving, wastes gas without moving you lot anywhere. When possible, cut the engine to save on precious gasoline.^[7]

Avoid rooftop cargo carriers. These greatly diminish your cars aerodynamics, slowing your car down and causing you lot to utilize more than fuel. In general, towing trailers or loading up the trunk is a more fuel efficient option.
7
Keep your tires well-inflated. Nether-inflated tires can lower gas mileage by 0.3% if all four tires are low. Using the complimentary air pump at nearly gas stations, inflate the tires up to the PSI recommended in your owner's manual.^[8]
- Some cars list the proper tire pressure on a sticker in the driver's side door or the glove compartment.
viii
Supersede your air filter. This is one of the cheapest and easiest ways to bump upwards your fuel efficiency. Make sure you buy the correct filter for your car by bringing the brand, model, and year in to your local automobile store and asking for recommendations--every auto needs a different filter.
- For newer cars, replacing the air filter will not aid fuel efficiency very much. It will, however, brand it easier for your car to accelerate without issues.^[9]

It depends on your car make and model and the engine RPM (revolution speed) and other factors.
Question

Can you explicate more clearly most starting mileages and subtracting closing mileages in step seven?

The starting mileage is when he concluding refueled his tank. He had a total tank and collection 389 miles, and then refueled with 12.5 gallons. The starting amount is 12,500 because the person did not reset the odometer to 0 before he started. Otherwise, this is the exact same thing in the instructions. He already drove 12,500 miles, and now he drove boosted miles; in social club to find the distance, you must subtract.
Question

How do I summate mileage from my last refill until the current refill if I had recorded the distance covered and fuel filled?

Y'all can only exercise that if you recorded the mileage on the odometer from the last time you tanked. If non, you will have to record it now as well as the next time you tank. There is no other way if the record was not kept unless you lot happened to take moving picture of your dash during your filling.
Question

How tin I calculate reimbursement for concern ventures in my own car?

Keep track of all of the miles y'all drive on the clock from your starting point all the fashion to your arrival betoken. Y'all can do this with the odometer on your automobile. Find out what your company reimburses per mile and calculate how much you're owed for your reimbursement.

Observe the posted speed limit.
Don't speed upwardly and slow down irregularly, it wastes fuel, specially in big SUV/Sedan type vehicles.
There's usually no point in turning off your car at stoplights, since you normally but need to wait no more than than 2 minutes if at that place'south not much traffic. Simply turn off your car if y'all're absolutely certain that information technology's better to turn information technology off (e.g. waiting to option up someone at the airport).
