breaking in basically is just not having the pedal to the metal for about 1,500 miles. just take it easy. nothing special.

IMHO, running a car pretty hard has helped every car I've done it to.

1. My Honda, bought brand spankin' new was kinda sluggish up until about 25000 miles. We then went of a 300 mile road trip, truckin' it 100 MPH most of the way. After that, the car has been lively and quick.

2. Green Daewoo - Driven under the harshest conditions, taught 2 people how to drive, punished by me personally...205,000 miles and counting. Compression is great across the board.

3. Mitsubishi Lancer Evolution IX MR - At brand new, we'd let the oil heat up the turbo, and "give it the stick" a few times during the mandated break in. Now at 6000 miles, its completed a cross-country trip, is excellent with gas, doesn't burn oil (Mitsu is notorious for this), and in races with an identical car, it pulled ahead.

However, since our Daewoo engines are cast iron blocks with fairly old designs, I'd follow the easy break in. Especially if the engine has been rebuilt.

New engine ?...great !

Everyone has their opinion.
I would break it in by doing the following stuff:
Don't drive it too fast.
Don't go over 60 mph. If you do have to? do it than come right back down.
Don't stay at any constant speed. Fluctuate the speeds like 50 for a while 55, back to 50, up to 60 etc....
In high gear, floor it for just a few seconds every once in a while.
Don't sit with it idling more than two minutes.
Watch the temperature gauge. Keep an eye on it at all times.
Don't let it over-heat.
Do all of the for about 800 to a thousand miles.
Than change the oil and filter.
Than drive it normally
Change the oil and filter again in about two thousand miles.
After that what ever is recommended. I try to change mine about every 3 thousand miles.

Have fun !
