Technically speaking Synthetic oils uniform size molecules reduce friction and increase
flow more than straight mineral oil variable size molecules...

Uniform size molecules of synthetic oil

Variable size molecules of refined crude

My atv is a 01 suzuki kingquad 300, so it might have 20hp, but then it also spends alot of time moving 2000lbs of quad, rider, and trailer up my hills.


Just look at the wide range of oils in use today and yet no one
complains about clutch slip when new... so its possible that
understanding what constitutes a "good spec" has more to do with
clutch age than oil in question...

I just ran Bel-Ray 10W40 motorcycle dino before that. I don't know if my clutches are all that worn though even now, as they don't slip much as I always match ranges to the useage. So even starting to move a full load on a grade only takes 1/3 throttle in the lowest gear.
