which motor oil do you guys use?

[bikerboy]

Use any oil that you want but it is not going to cause the valves to burn because the bits that burn on valves are the heads and the are not near any oil.
A good way of deciding what oil to use is to study what is being recommended by BMW for their cars over the years and what the change intervals are with the newer oils. Now that they put fully synthetic into some of the cars, they only change the oil every 40,000 miles!

I tried Mobil Delvac 1300 diesel oil - I think the last change was just Supertech 15-40.

I saved the Rotella syn for my diesel jetta.
