OIL - regarding the API service rating & JASO MA/MA2 - which is more important?
Okay, this is not an oil brand question; rather it is a question regarding the API service rating for a 2013 STS SM5. I have a couple of brands in mind for my upcoming oil change BUT bothe of them have an SN rating which if I remember the manual says not to use. They are both however rated for wet clutch with a JASO MA/MA2 rating. So should I pay more attention to the API or the JASO rating. The choices are all motorcycle specific oils. SUGGESTIONS?????:banghead::helpsmilie:
Castrol Oil Full Synthetic
I was on the Wal-Mart site and looked @ Castrol Oil Full Synthetic, for motorcycles. I did not see any.
