How to break it in?
This guy advocates running an engine hard to break it in.

That's very interesting. It explains why some old guys say one thing about break-in and young guys have a different opinion.

At least he has actual results to back up his claims.
And while many "old mechanics tales", are held as gospel today, sometimes we forget that technological changes may eliminate many of them. I wonder though if you can apply his theory to multi-cylinder engines?

I've read before hard break-in makes it go better... but the engine won't last any length of time.
Who knows though?

Cummins posted this on their website on a FAQ page for Dodge owners who were new to the 6BT a while back, regarding their recommended break-in procedures.

I've seen this before, it might work on motorcycles since you rebuild them a lot more often then engines in cars, plus motorcycles are most of the time for fun, very few people here use them as actual transportation. I don't remember but did this guy post how long those engines run afterwards or how often they come back for another rebuild? Probably not.

For bike engines, we used to have a pretty strict break-in for air cooled engines, as they have large tolerances.
You didn't beat the crap out of them. Not a chance. But, you avoided constant throttle situations (long highway drones at a set speed) and deep throttle low rpm running. Also, no snapping 'er to redline. The regiment was to vary your speed, make sure the engine wasn't shut off cold, and load the engine but not lug it. After 500km's, we'd dump the oil, swap in Mobil 1, put more stress on it for the next 1000km's, then another oil change. Then it was WFO and block-long wheelies! With that break-in, we had air cooled 11,000rpm engines lasting over 100,000km's with ease. I'm sure the 3K Mobil 1 changes had something to do with it too... I've followed a similar but less extreme "system" with our cars, and have yet to have any car suffer any kind of premature wear. In fact, we get some really high mileages without problems. Maybe I'm not doing it "right" but I gues I'm not doing it wrong either...

The guy could have saved a lot of time by just saying to break in the engine in like newlyweds in a motel.
