'07 JKU 3.8 here with 95k+. I was going through a lot of oil at first (at about 25-30k miles) using 5w-20, switched to 5w-30 and it still consumes some oil, but the oil consumption has slowed dramatically. I've never gone back to the thinner stuff and I have no complaints.
No scientific analysis, but the engine seems to use up less oil when I use conventional dino, it just drinks synthetic (either mobil 1 or castrol).
My dog is worried about the economy because Alpo is up to 99¢ a can. That's almost $7.00 in dog money.
