fill up your tank, make sure it is full write down mileage when you do. drive vehicle fill up your tank like you did before write down new mileage take new mileage and subtract old mileage: example 44,500 first recorded mileage 44,900 second recorded mileage Subtract 44,900 - 44,500 ________ 400 miles Now divide the 400 miles by the number of gallons you put in the car the 2nd time. Let's say it took 20 gallons 400 divided by 20 = 20 ...that is how many miles you get PER gallon of gas. For every 20 miles you drive, you burn 1 gallon of gas. last edited by Laces12 at 9:37 am on 11/19/08 edit was bubtract to subtract
