I anticipate having the car for a long time, and am willing to strictly abide by this if necessary (1,000 miles logged so far) to have a healthy car with a long lifespan, but of course I'm also dying to open it up and see what high revs feel like.

After warmed up go ahead and light throttle up to 5000-6000, give it half throttle some times. Smooth, slow shifts in a manual, no sport mode yet in auto.

After well warmed/heated up, go ahead and push the throttle further (gradual push, no jabs) to work the car a little harder, especially in 2nd-4th. Rotate doing this to 4000, and to 6500 in each gear.

Idea is to "break in" the mechanical components using their entire range (though I'd keep it under 7000 rpm), so that all components have been worked in the range where you'd be using it as a sports car.

Driving it under 4200 up until 2,000 miles doesn't mean you can start driving it hard at 2,001 miles - half the car hasn't been worked in yet.

I also change the oil at just over 2000 miles and every year ( about every 3500 miles). I have not added any oil yet (currently at almost 8000 miles). For the first 2000 miles the oil level dropped two bars. For the following 3500 miles the oil level dropped one bar. Now the oil level barely moves.


You will get all kinds of advice but I always go "by the book".
