BMW syn doesn't seem to get the best UOA results. I decided to try either Mobil 1 0W40 or AmsOil. GC is actually easier for me to find than Mobil 1 0W40 or AmsOil. I also want an oil that is BMW LongLife certified.
BYW, I don't understand all the "it may change" comments. Look at the last 2 years of Mobil 1's formula changes.
Oh, was this a rhetorical question?
