The fully synth. is the best, but the semi is adequate. Both are far superior to what your engine was designed to run on.

Have you ran an m40 on 5w 40? Everyone on the facebook e30 zone says to go with 10w40 but I read on here 5w 40 is better?

So are you going to trust the Facebook page, or the forum with three stickies on this topic written by a qualified oil professional, as well as the Wiki?

Your choice.
