Then had an 01 330ci which also ran absolutely perfect, as if new. Got rid of it at 140k.
Now I have a 09 335i at 27k, bet your butt I'm using mobil1 0w-40. I only PRAY this car would run half as good as my old 3-series.
Yeah. People really overthink the oil thing. A former tribologist(sp?) who had 30+ yrs experience once told me that oil related failures are very rare and that in the end all oils which have same OEM cert perform about the same. That's the point.
