I figured mine the old school way...fill it up, drive it and then fill it up and divided the gallons added to the miles driven.
My driving is about 70/30 city to highway and I averaged about 22.79 mpg in my 2007 pretty much stock 2.4L 4 door G-6 with automatic transmission that now has 89K on it. Its a second owner vehicle that I bought off a impound lot, so its not like I have owned it new and babied it all these years. The only mods to date are K&N Air Filter and I am currently driving with a check engine light for a catalytic converter code. Further more this is Texas and you better believe I am using the A/C!!! That's code for "its still hot here!". Just saying...
