Break-In a New Car

RedlineHR

All I can say is that when we bought my wife's 06 350z 6mt, we drove it like we stole it right out of the gate. I wanted to see how it stacked up to my M3 during the test-drive.

When we bought my 06 350z 6mt, I broke it in 100% TO THE LETTER!!!!

Hers still runs perfectly and burns zero oil. I never clean out her tailpipes and they are always always clean

Mine burned a quart of oil every 800 miles. I cleaned out my tailpipes every week and the were black inside by the next week. I traded in my piece of crap 06 for an 07 with the HR engine. I totally disregarded break-in on the 07 and it burns no oil. It also runs very strong.

I am sold on break-in = BS

YMMV...

I always do the break in. Usually 1,000 - 1,500 miles just to have piece of mind.
