I try to not drive mine "flat out" (pedal to the metal) for long
periods of time. This reduced temperature load. I keep cruise
speed between 55 and 65. Obviously going faster means more wear,
but the trick is to find at what point wear increases dramatically.
I don't have a definite answer.

The diesel already has an oil cooler and doesn't seem to overheat.
(I tend to think that the people who report that VW diesels run
hot either constantly run them flat out or have some cooling
system problem). I use CG rated diesel "fleet" oil, mainly beacuse most 
regular "car type" oil no longer have a diesel rating.
