Engine break-in, Which is the best way? Options

[HectortheRican]

I'm trying to break in my motor as quickly as I can before Saturday or else I won't be able to take my car back to Albuquerque with me for a while.

The shop that rebuilt my motor and my mechanic all told me to do a slow break-in. You've all heard this one: Take it slow for 500 miles, change the oil/filter, take it slow for another 500, change the oil again and you're good to go. No highway, no higher than 55mph, and constant speeds are bad, mmmkay.

But I've been reading online and found a contradictory method that seems to have a lot of evidence against the manufacturer and mechanic recommended slow break in. It's called it's called the MotoMan method (here's the link: http://www.mototuneusa.com/break_in_secrets.htm). This one says that you should start off quick and hard in order to get the rings to seat properly and drive it normally for a little while and you're good to go. The biggest evidence against slow break-in that MotoMan has is that with the slow break-in, the cylinder walls are likely to glaze and the rings will never seat properly, thus causing oil burning and other problems down the road.

What are all of your opinions on this?

I've already started breaking in my motor and I'm 200 miles in. I didn't do it slowly, but I've been driving normally, except no hard acceleration and no constant speeds. I haven't gone on the highway and haven't gone faster than 45-50 mph.

There would be some pressure with the drivetrain in 5th. But of course, the objective would be to slowly and softly break it in at various rpms. Little strain would be ideal with the conventional break-in method. Im meerly presenting you with another option than going out and racing your car to break it in.

I vote put it on jackstands and use the cruise control to put 800 miles (1/2 a tank maybe) on it. Its a for sure way to get you car ready to drive it 11 hours to New Mexico. Im the only person in here giving you critical thinking because Im trying to provide ideas.

Good luck with it however you choose. It probably wont make a huge impact on the life of the engine anyhow.
