Break-In a New Car

370Z Purist

Doesn't make a difference. When I downshift, I just make sure to be going sufficiently slow so as not to make the car rev itself above 6000. I break in my car a little different, I vary the RPMs and go different speeds, brake smooth, brake a little harder, etc. But I go to 5000, not 4000. I think that's just a bunch of crap to keep casting debris from going around too much. If I get to 1k miles this July, I'm doing an oil change. If August comes and I still haven't clocked that much, I'm doing an oil change.

Frankly, there's also a break in and bedding period for your tires, clutch, brakes (pad and rotor) and even your e-brake!
