[QUOTE="turbology, post: 350353, member: 10223"] Agree with AstroBoy. The term "Synthetic" is very over-use in US soil, but is not so bad than only equilvalent to semi-sync in Europe. Trust no word "Synthetic". Read the spec and qualification. For what reason ? Try to get few more ponies ? :D 30 weight is fine for normal use. But if you rev as much as I do in this Malaysia hot weather, extra protection from weight 40 is never a bad thing. My opinion, weight 30 is too low in cSt in high temperature, and HTHS protection. And if I remember correctly, BMW recommend 5w-40 Castrol EDGE motor oil for M3-E46. It might be for some other reason but I go for the theory weight 40 give better protection when you drive your car hard ;) [/QUOTE]
