If you are out of warranty, yes. If you are in warranty, do what Toyota says.So, I just was able to upgrade from my old Avalon to a newer, '11 Camry, V6. Looking thru the book, it still recommends dino oil at a 5k OCI, which I was surprised at. I thought by then, they be recommending synths and 10k.
Would it be OK to go with the synths and the longer OCI? I'd rather not pour thru all that oil if it isn't needed.
