Before your car even left the factory floor the engine was run hard multiple times to redline. So I wouldn't even give it a second thought.

Unfortunately, the only thing really "harming your engine" is keeping it UNDER 6K RPMs. Buy doing so you are risking incomplete piston ring seating and potential oil consumption issues. Not trying to start another hard vs easy break in controversy, but those of us who know from experience, will NEVER go back to the "easy method" . BTW, I am not advocating that you Beat the car. Only that WOT to redline from day 1 is not only acceptable but beneficial. I am aware of NO ONE who has done the Motoman technique that was sorry or had persistent oil consumption or engine problems. IT just works whether you believe it or not. http://www.mototuneusa.com/break_in_secrets.htm

My brother in law is a mechanic and I let him take my car out for a run and mentioned to him it was in still the break in period. He took off like a bat out of hell red lining the car immediately.

As soon as I started to lay into him, he started telling me that the way I was breaking in the car was doing the real damage.

I don't know if he is right or wrong, but I was sure glad to get him out of my car.

Is Motoman right or wrong???

Hi guys,

I am picking up my car tomorrow and really glad that somebody asked this.
So, should I follow motoman's advise to run is hard or follow the manual?

I've been redlining my car in every gear (every day, multiple times) since i took it off the lot with 40 miles on it, the cars can take it. I now have 150 miles and have taken it to 120 on the fwy.

I've had my 328 now for about two weeks and i've never seen this atricle until just now. But I'll tell you from my experience this is how i have always broken in my cars. I had an 02 1.8t. the only thing that didnt fail on that car after 125k miles was the engine. It was faster than most other 1.8's when it was still stock and still ran strong until i traded it in. I've done this on a rebuilt 84 911 carrera and rebuilt 92 994T. so take it for what it's worth. But i just changed my oil too. i'm at about 300 miles right now.

this is probably the most confusing topic i have researched. everyone has a different opinion. now i know the engine has been red lined many times before the car arrives at the dealer(from what i have gathered). Then why is bmw telling us not to red line it until those 1200 miles? something about the rings right...but didnt they red line and force the engine to seal properly? and then why put a car in the consumers hand when there is a possibility that they can damage the engine? something just doesnt seem right....

This is a common sense issue. When is being CAREFUL ever the wrong thing to do? Don't redline until the engine has seated.

Didn't hear it anywhere, I actually saw them do it at the factory. The car also gets a complete workout on the dyno at the end of the line - including being run up to about 120 mph.

You're welcome to provide information to the contrary if you have reason to dispute. It's not exactly shocking or new and it's been discussed here before on multiple occasions.

Excuse my suspicious nature, but that just sounds like a load of B.S. to me. There would be no reason, from an engineering standpoint, to take a brand new engine and run it up to the redline multiple times before it even left the factory. But of course, as you say, if it's been discussed here on multiple occasions, it must be true.

Well, there are people on here that have some credibility based on their history with BF - I can immediately name a handful of members, and hopefully you could too that have demonstrated that they know what they're talking about. Coming from members with respectable histories = more than just random internet fodder.

BMW, like pretty much any other automaker, should and does test the parts they put in their cars through the normal operable range of the component. Redlining the engine is normal - and from a QC standpoint how else do you verify it actually hits all of its operating standards before sending it into the world? From the day it's driven off the factory floor it has to perform flawlessly to redline. The dyno tests are very interesting - the car is run in drive and reverse through a series of acceleration, deceleration, and various staged steady-state tests while numerous different systems on the car are checked. There's a monitor above each car that shows a graph of the progress of the test and the vehicle's speed, among other factors... hence how I know they ran them up to 120.

It's shocking how piss poor the knowledge is here - the engines are indeed red-lined prior to leaving the factory; do you honestly fathom that a mass automaker like BMW would fail to thoroughly test the engine prior to releasing it to a consumer in the hope that they will abide by the break in rules and not ruin the engine? They take the engine to max capacity to make sure that when it inevitably happens there's no surprises for each individual engine. I for one am glad they do this so i don't have to worry about it.

It's standard practice among many manufacturers and has been for years.

I suppose the fact that i have a few friends that are engineers, 2 of which work for Mercedes attest to this must be inline with your worthless comment.
