Any updates?
I use whatever oil is on sale. Apples to oranges but I did the same for my 100k mile Subaru that was pushing 24psi on pump 93. Personally I don't think there is a *bad* name brand oil out there. The only diff I could see/hear/log were with viscosity. Penzoil ran thin while Castrol GTX made my engines run a little quieter. Anectode, I know!

Just an FYI, Rotella T6 5w 40 has very high ZDDP levels
