Rotella has a super reputation, but it may not be the right choice for an ATV.
Some ATV's require an additive for the clutches. I can't remember the spec, but it's there & not present in other oils. An old Honda dealer once told me he was out ATV oil so he wasn't giving me a sales pitch cause he couldn't sell me any if I wanted it.. But that I should use ATV specked oil. Didn't matter if it was Kawasaki, Suzuki or whatever, just use an ATV specked oil.
I do.
