Looked thur Auto Zone's oils today because I had nothing better to do. There sure is a bunch of them anymore. I may go with the Mobile just because I've always liked to keep them on what they are used to. I wouldn't want to go Dino with it now I don't think but I have some in the garage and I already have a filter......:Avatars_Gee_George:LOL. I really don't think brand is anywhere near as important as regular changes. I'm thinking this fancy oil could go a little longer??? I always tried to change Dino at 3500. I'm thinking 5000 with this stuff?? Longer would hurt my feelings. I would be Offended!!!
