[QUOTE="UnleashedBeast, post: 11396135, member: 112023"] I will say that I've never really been found of Rotella, even though it does return good UOAs on BITOG. Rotella uses a mixed formulation of magnesium and calcium as a detergent additive. Some of the tribologists have suggested that magnesium has the tendency to build up deposits in a gasoline engine. I don't know the details, or how severe...but I understood their explanation of the process. My predictions, Rotella will shear to a very light/heavy 30 grade within a 3,000-5,000 mile interval, just like Motorcraft 5W-50. The TBN "detergent additives" readings should look good, as this is a primary diesel lubricant. They commonly have very high TBN virgin content. Let's wait to see how accurate I was. ;-) [/QUOTE]
