This is a bunch of UOAs for my daily driver - 1991 BMW 318i. The latest one is schaeffer's 9000, and the previous few is rotella syn. Only the last two are conventional oils. I like 5w-40 for this engine.

I would run the 9000 one more time with a follow up UOA, but the Rotella seems to be working very well.

Any chance of you abbreviating the oil names (Delvac1300-15w40, RTS ..PZLL-15w40) and reduce the spacing ?? While noise, it appears that the AL in the last sample tracked with upticks in Si, Na ...but still minor.
