the newer pennzoil ultra pureplus has a much higher NOACK of 11.5% so i cant comment. however, ive moved to the 10w-30 version which has a super low NOACK of 5.7%. no burning oil so far and i'll have a UOA done in a few months when i hit the 6k marker

Yeah, I use 0W-40. The oil isn't as thin as 5W-30 when it gets up to operating temp, therefore maybe it won't pass by the rings if you guys are burning oil. I've used it for about 14k miles now. No issues at all. Doesn't the GT-R come from the factory with 0W-40?
