I'd agree with that, both my diesels saw a fairly hard life [ compared 
to a gasser] lots of high rpm freeway miles, either camp lejeune to ny 
and back twice a month many moons ago ['79 diesel rabbit] or my 500 
miles a week trip to work now and I've never had issue with the rabbit, 
don't suspect I'll see much when I do the head gasket on the golf in a 
couple weeks, which would have been done a month ago had i not hit a 
deer on my motorcycle and busted up my right hand badly.
