Amsoil 5w30. Manufacture recommends changing amsoil every 7500 miles I do it at 5k. HOWEVER at 5k miles, what sold me was the oil isn't even broke down yet, it looks like your draining fresh oil.
I think tho that amsoil, royal purple are all comparable. Oh and I run lucasoil in the rear end and ps and amsoil in the tranny as well.
