With the exception of the hydraulic oil and the coolant, every fluid in my car is not on the MB approved list ... am far less concerned with that (my understanding of this issue is that something small or silly keeps products off a list like this ... like Shell not presenting Rotella T formally for testing ... or testing start intervals mean new products arrive between ... or, bad feelings between the various corporate suits, etc).
Suspect that if it meets other SAE etc standards that it would also be a suitable product.
Interesting point, though ... other comments (this should get juices going!)
