Its not just for the clutches. all atvs have flat tappet cams which require the same additive package that keeps your wet clutch alive, zink. I use atv oil in my mud truck because it has the zink for the flat tappet cam in that truck. modern vehicles have roller cams so the zinc is not required, plus the small amount of oil that any engine consumes will ruin a catalytic converter over time if its chalk full of zink so car oil has been going in the direction of less and less of these additives as emissions gets tighter. Friction modifiers are not what ruin the clutch. the lack of zink does.
diesel oil has zink in it too but its also dwindling as emissions tighten up on diesels. on top of that, diesel oil has a ton of detergent which kind of hinders the effects of the zink from what ive read. rotella t changed there formula and they are down to i think 400ppm of zink. i buy mobil delvac for my diesel truck, supposedly it has 1300ppm of zink in it thus the label saying "delvac super 1300" but i bet they changed the formula by now.
point is, just buy any motorcycle or atv oil. anything for off road use will have the additives you want.
and for just plain clutch systems like on a dirt bike for example, i just use automatic trans fluid. type f has no friction modifiers in it, so thats the one to use.
