My 06'Infiniti FX35 recommends 5w-30 so I've always used Mobil 1 EP 5w-30, but recently went with M1 advanced fuel economy 0w-30, didn't see a difference whatsoever. So I'm probably going back if I decide not to try something new. I'm hearing really good things about royal purple and amsoil 5w-30. So I'm contemplating on going with one of those. Is anyone familiar with the two?
BTW Costco has on sale right now 3/1 gal of Chevron Delo 400 Motor Oil SAE 15W-40 for $35 (link below). Would that be an efficient motor oil for the FX35 in Winter?
