It's a tough one, plenty of Detroit Jimmy owners put whatever in there and will report good lifespan's. Grade aside if you are putting a low ash oil in as required then it won't come in a multigrade anyway's.
Multigrade polymers have come a long way from the first attempts which did not hold up, however for me heavy duty diesel wise you just cannot go wrong with a single weight.
On another note back to this thread nice adaptation of the CDR.
