Some folks use an SAE 30 oil, others use ATF. Just don't use any synthetic motor oils or anything with anti friction additives as this can burn out your clutches.

So you say no synthetic oil, so the ams oil 4 stroke  use is not good. Or do you mean synthetic motor oil.

Atf will work good if your seals are up to par and you should change it every ride or so.

lots of good oils out there, the only thing i suggest is NOT using BelRay Gearsaver.  Caused my tranny to start pitting and rusting.
