Google search brought me to this post, informative indeed.

I did read about API, ACEA and JASO but it seem that many of the members here discuss about API only. Why eh?

I remember back then during my study, API is American Petroleum Institute?
Is API only apply to the cars being sold in America? Since ACEA lubricant is specially designed for Europe car.

Which one shall we follow for Malaysia cars?

There are so many engine oil brand out there, really confusing to me. Now, I'm still sticking to major brands, pay a bit more for the peace of mind.

API and manufacturer certification, which actually more stringent when come into requirement?

Chat with a chemist yesterday and he mentioned that of MB229.5 specification, the oil will require to have less than 10% NOACK value being heated at 250c while for API SN, as long as it is below 15% NOACK value will do.

So is it safe to say that the oil meeting API SN but not MB229.5 can be more inferior to those meeting MB229.5 spec?
And whatever meeting MB229.5 spec will be automatically in the group of API SN or perhaps the future grading, SP?
