I still have a bit of the rogue in me and going with Mobil 1 is a bit too main stream. Wal-Mart offers Quaker State as a synthetic option at $29.95. If I understand correctly QS is group IV. If my present ST dino easily does 4K in my Elantra this should be good for 7.5-- no??? Anybody have any experience with this? I notice that there's no UOA's on it.
