Gas mileage

[mbdougl]

I don't how some people are figuring the mileage but there is only one way to get an accurate result (below). Does anybody do this are all we all just trusting what is says on the dash, mine goes fron 11.9 to 12.9 and never changes even if I drive all highway. I wonder how accurate it is?

Best way is to fill up your tank, then set your trip meter to zero. Drive your car until you need gas the next time. When you fill up your car again read how many gallons of gas you put in then take the trip meter reading and divide by the gallons of gas to get MPG.

EX. 350 mile were driven and you placed 10 gallons of fuel back in the car. SO 350/10 =35MPG
