I know I've seen somewhere on the forums about the accuracy of the onboard MPG calculators in cars, but can't locate it right now. Seems that they have an error of +/- 7% as I remember...is that right? My '07 Camry has an electronic MPG calculator, and I will be starting a gas log to compare to it. Just wondering if anyone here has had any real world experience as to how close these onboard displays are? Thanks!
