the computer says my mpg is 19.9 but my calculations indicate it is about 14 mpg
i calculated this way:
when i fill up the gas tank, i would reset the trip counter.
the next time i fill up, i would fill it up the tank
the gas pump would indicate how many gallons i have bought
and the trip counter would tell me how many miles i have driven
so miles driven/gallons used = mpg = 14.
