Uhhh the lie-o-meter will say your mpg is whatever it wants to say... that being said best I ever hand caculated(mind you 2wd here, SCSB truck, so only 7k) was 22 mpg, with a load in the bed actually, so I probably weighed like 8k, anyway drive it nicely down the highway and you can see some decent mileage, just alotta other factors.. enjoy the tunes!
