My 2009 Fit Sport AT gets about 4-5 MPG less than the trip meter displays. Is this common? I see about 37 MPG driving to work but at the pump is it really about 33.

Is there a software upgrade to make this more accurate?

 

there have been many threads about this.. and idk if there is any software to fix it.
