No stories Dean. I'm the original owner, I have all the maintenance service records as well as the dealer's initial vehicle inspection report. Mobil1 15W-50 was in the crankcase from day 1 until I changed to dino oil in 1997.

There are only 10 kinds of people in the world--those who understand binary and those who don't

I accept your claim that the dealer put in Mobil 1 from the beginning but that doesn't show what it came with from the factory. It's not something that can be documented - on the production card or anywhere else. But Mercedes wasn't putting Mobil 1 in from the factory for 1988 models - not even close. The O'Keefe litigation and settlement a decade later make absolutely no sense in that context.
