Mine always got 20-29 mpg. Top up your tank and drive it until you have used about a half a tank, that would be about seven gallons. Seven gallons should get you 140-210 miles. So divide your miles by the gallons used and that would be your MPG. I hope this helps.

Is the check engine light lit?

Yes the check engine light is on . We put a tester on it it showed a misfire but the car does not miss it runs great just cant keep gas in it

Get the miss-fire fixed and fuel mileage will improve. I think you are over thinking this issue.
