"...a customer came into a shop recently with a 300SD that had 350K miles on it, original head, etc. another living testament to the reliability of Mercedes diesels, and the mechanic said she (the owner) comes in like clockwork for her 3000 mile oil changes.
You can't argue with that!"

Oh brother, another one. When are you guys going to get it through your head that this kind of info means absolutely nothing.

I heard that she washes her car every week, so therefore, if you wash your car every week, you too can go 350kmiles. Correlation does not imply causality. Get it?

Probably not. I think it's hopeless.
