Just a hypothetical question. If you buy a new 3 and run it hard from the start, not all the time, but every once in a while, just hammer it a little, will it really mess up the engine in the longrun? Not that I would ever do anything of the sort 8) .
While breaking in my 3, I didn't drive it hard, but I didn't drive extra slow either. I made sure that the engine was used up to about 4500 RPMs with firm pedal pressure, but no where near WOT. I took it to 6000RPMs once at about 300 miles on the odometer, but the situation warranted it. I am at 585, should be done breaking it in on the way home today. :bigsmile:
