Valvoline VR-1 vs. Lucas Hot Rod oil
The reason I was digging into the Rotella's was the fact they changed the formulation about the same time I was putting a new (rebuilt) engine in my jeep. The old engine was very worn and was getting a regular diet of T6 5W-40 the last few years it was running. For the rebuilt engine I wanted a non-synthetic with moderate Zddp. Plain jane stock cam engine. Ended up going with Ford's 10W-30 Diesel. Another few oil changes it will probably get something else, prob a 5W-30 to help in the winter and short trips.
