Correct Break In Procedure - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I edited this post, because people misunderstood some of my key points.

1) Do not excessively rev engine until 30 minutes of drive time in winter. It takes 30 minutes for the oil to reach the proper viscosity in winter. Much less during summer. Much less if you are using 0w20 synthetic.

2) While DRIVING ON THE ROAD, rev away through the entire RPM range, up and down, up and down, up and down. Redline it, and come back down to 0, and then slowly go back up to redline. As long as step 1 has been completed, you cannot damage your engine. Plus you really NEED to do this for proper break in.

3) When you decide to change the oil for the first time, the oil must be HOT for the metal filings to come out. So what you need to do is get the oil hot, and then also let it settle down for 10 minutes or so. Then immediately change it.

Thus in theory, a LONG road trip with the 30 minute warmup in the beginning, followed by constantly varying rev range, and concluded by an oil change at the destination after the oil settles down (yet still hot), would be the ultimate.

As a practicing "break in" specialist who has seated thousands of race engines I do agree with some of what you have outlined just so long asthe engine is on a dynometer and not in the car. You forgot to mention the most important factor. Load factor. Your also referring to engine dyno break in procedures which has no use for people who already have the engine in the car. The dyno break in procedure your referring to can control load in BOTH directions,, up and down through the rpm range. You cant control the decreased rpm load in a car like you can on a dyno so the "up and down" rpm range your referring to has no use at all in a car.,. Free revving or revving with little to no load up and down through the RPM range does little to nothing for ring seating.

I see no reason to use the break in procedure you outlined unless your on an engine dyno!

I despise misinformation and as a professional engine builder and designer I will not let it stand.

30 minutes? really? I have no idea how you came up with that random number.

Again, really? Just spinning it in neutral or park? You might want to ease into the throttle and take it to redline smoothly them back off, all while it is in drive

Hrmm....I hope the proper oil filter catches the filings. That is what oil filters usually do.

I would suggest a first oil change after 1000 miles.

Yes you do it while driving, not neutral or park. Thats why I mentioned the long road trip...

30 minutes is not a random number. Thats how the major oil companies measure and determine the viscosities of their oils.

For example, do you think 5w-30 refers to non-operating temperatures?!

To Mr. Morgan, all I meant by "up and down" is to constantly vary the RPM's through the entire band while driving during the break in period.

30 minutes of idling or 30 minutes of hard spirited driving? I can see a HUGE difference in the 2. That number is just plain wrong anyways. It takes roughly 3-4 minutes for a motor to reach closed loop mode. Do you know what closed loop mode is? At the 6-7 minute mark the motor will be 100% at full operating temperature, depending on outside ambient temperature, and the load placed on the motor. The oil pump will be able to EASILY flow every ounce of oil throughout the motor withing a few minutes of normal driving. That oil will be at optimum temperature a few minutes after that. Under a loaded scenario, all of these steps will be shortened as well.

I'm not sure where you have been studying to be a student of proper engine break-in.

Here's a simpler way to break a new motor in.

1. Drive the car normally.
2. Don't beat the snot out of it until it is at operating temperature.
3. Don't beat the snot out of it all the time.
4. Drive the car normally.
5. Change the oil at 1000 miles for the 1st oil change.

I think it's a little bit funny that you have edited every one of your posts, and you drive a Taurus while posting on a Camaro forum.

I remember from my college days looking at a paper I'd finished the night before thinking "Damn, that made alot more sense last night when I was drunk".

I think Darin Morgans thread will suffice in engine break in procedures.
