OIL
I just don't understand how a oil can be API certified "SM" and also JASO MA. Since the SM rating requires friction modifiers that aren't recommender for wet clutches. Almost a oxymoron in the scheme of oil ratings.:dontknow:
I use the Rotella full syn.
I noticed that the new Rotella T6 full syn is now JASO DH-2 MA certified!
