The AMSOIL AFF 0w-40 would be a great choice. Bel-Ray oil tend to have a weak (IMO) additive package and the oil you linked to is VERY expensive for a mineral oil.

I've tried polaris oil, amsoil, bel-ray, and klotz. By far my favorite is the klotz 20w-50.

use ps4 polaris synthetic oil its what they reccomend and it works good unless you want to race. if your going to race use 0w-40 synthetic oil.

Ps-4 is shit and only lasts about 5 hrs befpre it starts to shift hard....
