Have been runnnig castrol 5w40 and Agrol 0w30 lately and it runs well on both. Then I have come across some posts here that says the 4.0 may be better off not runnning full synthetic.
Well, I can find 10w40 semi synthetic API SL/CF quite cheap. Would this be a better choice? Maybe in the summer or? The manual says any API 10w30, so I interpret that like I can do almost what I feel like. The engine is 2002 and has 50k miles on it.
