How important is break in ?

I tend to drive casually for 500 miles or so and then slowly ramp up the crazy. In over 30 years of new cars, this has worked out fine.

I was doing the occasional hard 0-60 pull at ~600 miles in my 2016, for example.

The biggest thing I know of is not holding a set RPM for any of the first thousand miles or so... No long highways drives using cruise control. You don't want anything in there to establish a wear pattern.

From the factory the car will want an oil change at around 2000 miles.

And yes, some engines like Chrysler's pretty amazing Pentastar have ECUs programmed to only allow the engine to make like 70% of max and the A/Ts shift early for the 1000 miles.

I m following the manual instructions, but sometimes, i feel the needs to have fun a bit. I remember the Z i test drove (not the one i bought), it had 200 miles on it and i did a couple WOT to the red line with it and the young saleman beside me.

So i can imagine how thoses 200 miles were done

I look at it this way. Ferraris, which supposedly have some of the more delicate engines out there, take their finished production cars directly to the track once they come off the assembly line.
