I used rotella for the first 150K miles, then ran LL gold for about 50K in my 5.9 Dodge cummins. Slightly less consumption on LL, but it always bothered me that it would take 1500 miles or more to look dirty, where the rotella looked like [censored] at 750 or 1000. I assumed that the faster it looked bad, the better it was carrying nasties out of the engine. Same cheap Fram filter since birth. Truck still runs great at 260K.
