Motor break in process...

[crX-RATED]

Everyone has their own story of how to break in the motor. Most people take it easy, go for maybe 500 to 2000 miles in some cases, to make sure their motor is fine. My question is about a newer method i keep hearing about.

Instead of babying the car, take it out, and in the first 20 miles, get on it a few times. Of course this is in a controled way, just not flooring it till redline...but logically it sounds like it would work.

I'll attach an article that explains this more throughaly, but basicily it says this: when you rebuild your motor, you get your cylinders honed to help seat the rings. Since the honing is so fine, it will wear out in or around 20 miles, not giving you alot of time to break in the motor. The idea is to push the car hard enough, accellerating and deccellerating while under a load, to make the rings seat while the honing is still there.

i've heard many stories of people doing this, and not having any problems afterwords. I've also heard of people breaking in their motors like this on the way to the dyno to be tuned, and they were fine for the dyno session. I havn't been able to locate any articles proving the long-term affects of this method, but like i said, it sounds like it would make sense.

And yes, i know you must change your oil frequently during the break in process, but i figured that was general knowledge. This statement is just for ppl like ben, so they wont bug me about it :p

So....what do ya think??:D

interesting...but i think i would still stick with the old method of babying the motor for a good 1500-2000 miles before getting on it

The link is broken. But I've heard of this method also. They use it often to break in motorcycle motors.

Until I get my own dyno and about 40 motors to just play with, I'm afraid I'll have to stick to the tried and true method of breaking in the motor as well. :(

well, i believe strongly in idleing it at 2k for 20 mins. then back to normal idle for 5 , shut it down. change oil
then drive about 200 -300 miles not goin above 3k, change oil. increase 1k rpm every 100 miles...wallah. 1000miles and your ready to rockn roll

When I was out at autocross feb. 2 there was some new nissan out there. It still had that big piece of paper in the window that tells you what the car comes with. They were getting on it but not to redline, it was sooooooo funny b/c everybody was like you better hurry so you can get it back to the showroom. It looked like they were either on a test drive or had just got it that day.

I would suggest a 1,000Mi break-in

I would use the OE oil filter
a 30W NON-detergent NON-synthetic oil

for the first 200mi dont exceed 3,500RPMs (increasing engine speed 500RPMs for every additional 200mi of operation)

No "steady-state" use (freeway driving at constant speeds and RPMs)

change both the oil and oil filter after the 1,000mi

and slap in some Mobil1 Synthetic...its what I use:thumb:
