lol i loose like 2-3 mpg if i shift at 2000rpm vs 2500rpm. i have a 5speed 4 banger s-10. if i shift somewhere around 2500 rpm i get 25mpg if i go lower than that (liek at 2K or under it only gets like 21-22mpg) course its an underpowered 4banger for that heavy of a truck...
im gonna try at 3K and see what happens. all i know is i HATE the speed limit of 30 mph.. its too high for 3rd gear and too low for 4th... 4th kidna labors and doesnt sound good at all. 3rd sounds high and the upshift light comes on...but i barely press the gas pedal(liek the weight of my shoe could drive it perfectly...
somehting else ive noiced is the wider tires(noticeably liek 1-2" wider with more agressive tread) and rims i put on for summer dont seem to affect mpg at all (maybe liek .3mpg or so) but it is a truck that has a buttload of torque for a 4 banger cuz its geared that way so maybe on trucks it doesnt make a difference.
