Dave,

I guess I have been risking engine damage for several hundred thousand miles then, because I use regular engine oil. Funny thing is I haven't experienced any engine damage. In my opinion, when they are talking diesels, they are talking 18 wheelers hauling tons of freight not pissy assed pssenger cars. There is almost no load on an MB sedan going down the highway with one person in it. I use DELO ( diesel engine lubricating oil) in my F-250 truck, because when it is on the road, it's pullin a load. Just my opinion.

Peter
