ATV Motor Oil API service label question: can I use SM in place of SG, SH, or SJ?

[Atlas shrugged]

I have a 2005 Can Am (or Bombardier if you prefer) 400cc Outlander ATV, and the manual says to use oil that "meets or exceeds the requirements for API service classification SG, SH, or SJ."All I can find anywhere is SM. Can I use this? Will the the wet clutch be adversely affected?

Absolutely. SM is the newest classification for oil ** the Society of Automotive Engineers. It is what you should use and will exceed all of the previous service ratings. Also make sure, although I'm sure it does, that the oil also contains the identification GF-4, which is the newest ILSAC standards for oil and really the most important part.
