A question for you, and also for other Ascent owners: how close is the mileage computer compared to pencil-and-paper calculations? I have had GM products that came within 1/2 mile per gallon, an MoPars where - let's just say the computer was as optimistic as Polly Anna on a sunny day.

I've alway kept record of my actual gas milage, and the car's estimate is usually higher by 1/2 to 1 mile per gallon.
I keep an extensive log of my fuel fillups and computer vs pencil and paper. When I have an engine hours meter available, I note that as well, so I can even see my vehicle lifetime average speed. Yes, I am a bit of a nut on this stuff, and also enjoy working with spreadsheets.
