[QUOTE="darianmacdonald, post: 1526085, member: 30500"] 5w40 will help with your cold starts. Tons of threads on it if you dig around. You will see more of a difference running 5w40 as opposed to running 15w40 with an additive (like Archoil for example). Or at least I would say anyways. However either will help. [/QUOTE]
