    HI, i was wondering why and is there anything i can do to keep my gas from burning up so quick. it is basicly when i hit the gas pretty hard. and i know it burns up more but, it seems like the gas gage goes down faster than it should. is there anything i can do to keep it from doing that?

    I put a higher tire size on at the begining of summer and didnt notice any loss of mpg. Suddenly I notice a drop from around 14.5 to 14.9 down to 13.3 to 13.5. Any ideas where to start? Cheapest fixes first I suppose, but I thought the forum might yield something "likely" to be the cause.
