A true way to check over all gas milage, is to record the consumption
over several tanks of gas, and then calculate it. I notice that some of
you figures were on less that 5 gal. fillups. This could be effected by
the way the car was sitting when you filled it, the senstivity of nozzle
on the pump, etc.
I have always done the 5 tanks fulls and then figure it.
