This is the new RT6 that is the mixed fleet oil (gas/diesel). It has a higher HTHS than Resource Conserving/GF5 oil in order to meet the diesel spec, and HTHS is what keeps the bearings happy providing a thicker oil film.
So whats the real difference between the Rotella 5w-40 diesel and the 5w-30 multi vehicle oil? More phosphorus?
