New Car Break In

Engine-brake often, don't stay at one speed for a long time, heat-cycle the parts by parking the car for a while (normal driving/stopping, basically, no road-trips).

Most new engines are finished so well that they are broke-in other than the heat-cycling by the time you have the keys in your hand at the dealer. All the micro-polishing and whatnot of the bearings makes long, laborious break-ins a thing of the past.

I would follow the advice aboue 4K/1200 miles, though, if for nothing else because if you got a defective part, they couldn't even try to wriggle out of replacing your engine. Crap happens. 4K rpm in a 370Z is plenty for daily driving. The engine produces a VERY! impressive torque curve profile.
