I totally agree....Is it just an urban myth that friction modifiers cause slipping clutches?
Urban myth? I'll tell you what..you put a can of "slick 50" into your bike, and if your clutch doesn't start chattering immediately I'll buy the next oil change and filter for you. If (when ) it does...YOU get to buy the replacement clutch plates. Been there!most of the diesel oils are fine, and some have had no problems with any car oil. Is it just an urban myth that friction modifiers cause slipping clutches? or is it the 150,000 miles? hard to pin it on the oil. Good luck!
yes i did--the po used rotella and mobile 1. when i would shift the shifter would actually kick back at my foot , and the noise of a clunky shift is quieter too.Did you guys who use the Delo and Rotella oils notice an improvement in transmission function after changing over:baffled:
