RPM's for a Detroit S60/10/2.64
Can anyone offer any advice on how to get the best mileage out of a Detroit with a 10 speed and 2.64 rears? (not my first choice, but I can't afford to swap at this point).
I find if I let my RPMs get up too high, all I hear is the turbo and watch my mileage decrease, however, if I keep the RPMs in the 1200-1300 range, the slightest whiff of a hill means I have to bury the pedal and/or shift, which.. there goes the mileage.
Any advice is appreciated!
Is this a good question?
