Number 1: don't enter it into a race as soon as you leave the dealership.
The hardest things about being an owner of a brand new car is having to discipline oneself against opening it up to see its full capacity within the first few hundred (or thousand) miles of ownership. This period of time is known as the break in period, and while that time frame can vary by car, it's generally not recommended to take a brand new vehicle with little more than double-digit delivery miles on a hoon festival upon delivery. That might sound straight forward, but not all of the break in rules are as easy to guess.
In case you needed any reminding, Engineering Explained breaks it down pretty clearly for us.
The first rule is the most obvious: don't thrash the engine, shifting at redline and revving it out, until the break in mileage has been cleared. The reason why is that the engine's moving components need the time to set in and mesh together properly. What's recommended is that owners vary the load and keep it under a certain RPM level. Contrary to what your buddy who's watched Fast and Furious a few times has told you, it's not good to give a new engine a hard break in. It doesn't do anything good for the engine, not even for motors designed for racing. Aside from tip one, which you've probably heard a handful of times, the rest of the advice is a bit surprising.
