How do you determine how many miles a gallon of gas you are getting in your car?

Answer 1

When you fill up, start your travel odometer at zero. Go until the gas needle reads empty and then push it a little bit farther. When you fill up again, divide the number of miles by how many gallons you put in. That will give you your mileage.

Answer 2

actually you do not need to wait even that long -top off ,write down mileage go 50 miles top off again and divide miles traveled by gallons put in -too easy
