Water is a byproduct of the combustion of gasoline, not diesel.

Again, we are talking about diesel engines here. More specifically, our Mercedes diesels. Short trips on diesel engines is not as hard on the oil as on gasoline engines. Short trips are not good for other things with our diesels but that's not the point.

Extrapolating any oil related information from information gained on a 1970 ford gasoline engine is pure fanasty.

The fact that you attempted to use it as a reason for your current 3kmile oil changes tells us plenty.

But as I said, your mind is made up and you continue to preach to the newbies how 3kmiles changes are the greatest thing since sliced bread.

And that is wrong.
