Jay: the synthetic Rotella is mult-grade and I've been using if for about 15,000 miles. I had the engine overhauled recently and the mechanic stated that the engine showed lots of miles but nothing else unusual. The engine replaced a Cummins 555 that was originally in the coach and was obviously a very used one. The mechanic told me that based upon what he had seen of the engine he saw no reason to change my oil type, but as the saying goes he could be wrong.
