Just wondering. Does anyone have a MPG vs Shift RPM graph? Max effiecency speed on freeway in term of MPG? Probaly will not use it on weekend fun drives but weekdays I may be useful
I noticed if I shift @ 2.5k - 3k RPM I get about 25MPG ave between Hiway and City. Spirited driving 4.5k then I get only around 23MPG. and pissed off driving shift @ 6.5k then around 20mpg.
Of course all this is one guy's data so probably not very accurate.
