And alternately, why would and oil carry the VW 502 approval but not the MB 229.3? The threads about Silkolene Pro S had me look into it. It carries the MB 229.3 but not the VW 502. Pentosin Pentosynth 5W-40, on the other hand, carries the 502 but not the 229.3. Why would this be?

The MB 229.3 spec is supposed to be a longish extended drain standard. It might also be a matter seeking the correct approvals. Pentosin seems to be marketing its PENTOSPEED 0W-30 VS as its 229.3 spec oil.
So would an oil like the Silkolene Pro S 5W-40 or the MOTUL 300v, which also doesn't carry many car approvals because it is a race oil (it is double-ester) be good to run in any car? The MOTUL E-Tech 0W-40 is ester-based and VW 502/503/503.1 but is not API SL, only SJ???
If it's SJ, then it might not carry the API "donut" if it's current. Could be it contains too much ZDDP to meet the API SL standard? Europeans don't care about API specs. It could very well meet the protection standards for API SL/SM.
