did you guys wait until after the first 1000 miles before driving more aggressively??

 

I never could, though would try for about a week Plus, you don't think your new car was ever test driven by someone with a heavy right foot?

I'm sure if it was such a huge deal for today's engines, there would be a disclaimer in the new car, just like everything else, from Toyota's Don't drive as fast as tested in the New Celica, and Caution Hot, No Du, on MCDonalds coffe cup. I mean, if lead footing your car around after you bought it, hurt the engine, and their is no disclaimer, thats a lot of repair work for the car maker.

I know when building push-rod iron block american engines, I do allow it to brake in, so the the rings and other factors I don't really see in most new cars "break-in".

 

I don't drive that aggressively to begin with, but I did let the car break in before I drove with the full throttle open a few times. (you know, for passing those slow people on the freeway...hehe)

 

I jumped on mine from day 1, and now at 3K miles, so far so good.

 

I waited for however long the book said to.

 

I drove more aggressively after the break in, but did floor it a few times on highway before 1K miles. How could you not?? Driving a new car is a special feeling...
