Shift points
I have 1998 e36 bmw 1.6L engine with 5 speed manual transmission. Normally I'm trying to keep the engine between 2k-3k rpm for economy. I feel that I could get better mileage by even lowering the speed and rpm but I'm not sure if it's healthy for my plain bearings. On which rpm would you normally up shifts and downshifts? Which rpm range and load are safe to drive without compromising on engine longevity?
