ive tested my avarage per se in a 2 week period from filling up to about half a tank(during this "test" majority of driving i did was steet driving) i love hearing the sounds of the exhaust so under normal street driving driving i shift at about 4k
freeways i do the same i would say my average speed under normal conditions is 75mph but sometimes i had the urge to punch it i do a couple of redlines
i also tend to hold gear on 4th just to hear the exhaust and have "instant"burst if i want it
i hope those made sense
with that said after half a tank i filled it up until the pump clicks
look at my distance travelled and divided it with the # gallons
the bad news and its sad to say i averaged 15mpg(with the way i drive)
but the good news this is the same average that showed in the cars readout meter so it safe to say it is preety accurate
