Z Oil Change: Miles or Time?

370Z Purist

Every manufacturer seems to vary a hell of a lot as far as oil change increments go. It's safe to assume though, that with change increments like that, they expect you to go a little longer. I believe most new Mercedes come with Mobil 1.

Consider that during cross-country races, cars are driven much harder at higher temperatures and much tougher conditions on only a single fill of oil. I think the Dakar Rally is probably one of the best examples (I remember this only because I think Mobil 1 did a commercial about how they're used in a few DR teams).

All,
here is my experience with M1 Full Synthetic. In 2000, we bought two new Jeep wrangler Sarahs. Both the Mrs's and myself had identical Jeep minus the colors. These were daily drivers at the time; 50-75 miles a day when gas was still kinda low. We did moderate 4x4 wheeling on the weekend and ran them year round. The wife did her oil changes at the dealership with what ever stuff they used. I moved to M1 FS. At about 74,000 miles I ended up smashing the oil pan. When I took the pan off to put the new one on, you could see the entire underside of the 6 cyclender engine as well as the inside of the oil pan. Both looked spotless. So out of curiousity, we took the wifes off to compare. I had to use a rag to clean out her oil pan with some serious elbo grease and chemicals. You could see it all burned on and discolored. Mine was spot free, shiney and looked brand new. We regularly changed our oil after 3,500 miles so I was shocked at what I saw. After that, I've run it in every car. Just my experience with it.
