Transmission Oil Preference

Post by Dutch-MI »

The Clymer manual says to use 10W-30 or 10W-40 in the lower end on the air-cooled KDX's. What do you guys like?

Temperature range? If you are in MI, I doubt 40 would be needed for the winter.

Which bike do you have? (signature.. hint, hint) :-)

I could be totally wrong, but I didn't use standard motor oil in my 84. I used oil made for power sports. In my head I was thinking the wet clutch would not like all the additives motor oil has these days. Oil is much different then it was in the 80s..

Valvoline makes a 10W-30 and 40 for ATVs designed for wet clutch.

I switched to ATF-F years ago and never looked back. So cheap too!
