For crying out loud guys - this is no different than any other manufacturer. Does Ford sell any of their cars (even the GT) warranted for competition use? No. How about GM? No. How about Toyota? No. See a trend here?

All of us bought a vehicle built, designed, and warranted for street use only. Nothing says you can't make mods to it for competition - buy you'll probably void the Nissan warranty (as you would similarly void a Ford, GM, Toyota, Subaru, etc., warranty).

Now lets get back to discussing what oil is best for our Z's!
