Oil Question

BrandonT

From the uoa's I've seen some of the "boutique" oils like Redline and Royal Purple have been disappointing. Pennzoil Platinum and some formulations of Castrol Edge seem to have the most consistently good uoa's, although they shear some too. This VQ motor really shears oil badly. For a conventional oil Castrol GTX gets pretty outstanding uoa's on this motor. Normally a good name brand oil will do well enough in most engines, but this VQ is kind of pain if you're anal about that sort of thing.
