I'm about to do my 500 mile change after rebuild. I plan to just go with a conventional Valvoline 10W40 and an additive w/zinc. My future plan is to go with synthetic. Do any of you suggest that I move to syn now or just get a few more miles under my belt. Also, for those that do use fully synthetic, what interval do you change your oil?
