How Do You Break In? Options

[chimet]

I've heard many say that you shouldn't baby your engine when you break it in or else it'll become "weak" later on...I've also heard people tell me not to push the engine too hard during the break in period? So could you nice people explain to me the right way to break in a car?

Many of you are way off the mark... constant throttle on a new engine? Bad! Engine broken in at the factory? No way! (As a note, cars are shipped from the factory dry, no oil or fluids)

I learned about this technique years and years ago, and I hold true to it on every car and motorcycle I have owned. Of course, you can do whatever you want right?

The exception I have noticed is for most of the Honda VTEC motors... the break-in procedure for them is fairly specific and regimented.

Wrong. How do you think the cars get from the end of the assembley line onto the back of a semi trailer? Do you honestly think they move them around with a fork lift???

The difference in performance from an engine that is broken in hard vs one who is broken it easy is minimal at best. Just drive it as you normally would, thats all you need. No need to baby it and there is no benefit from breaking it in hard.
