:devil:I just picked up my 350z sunday and put 500 miles on it already waisted a few mustangs and grapefruit shooters along the way

My .02 I don't care what the manual says. I still think you should take it easy on your new vehicle for the first few thousand miles. Let the engine break in (if you think engines don't break in, check your oil after your first 1000 miles) and don't rev the engines too hard at first. You will get a longer lasting vehicle out of it.

Nissan recommends 1200 miles below 4000 RPM in the owners manual. They say change oil at standard interval but I think an early change is cheap insurance. They aren't going to replace your motor just because you scored the cylinder walls and are burning a quart every 2000 miles.
