Occasionally go max load but not max rpm. Compression rings are seated by compression pressure and Wide Open Throttle at less than peak power or maximum engine rpm allows the compression rings to properly seat.

Meanwhile bushings and bearings like to evenly wear in, so we don't hit peak load or max rpm but gradually vary the load higher and higher to wear them in.

Disclosure: My ASE certification expired back in 1995 but nobody has reinvented the wheel on this so to speak.

OK, I guess my sense of humor is a little too subtle for most people. I think that the technology is still a few years away from having a vehicle do its own oil analysis - we will have to take an oil sample and mail it in for still a few years to come. Also, I guess that no one thought that an alarm sounding continuously was was anything out of the ordinary.

So no worries team, it was all a joke.
It was a god one. I rate it up there with gag posts seen elsewhere saying JB Weld works great on leaky oil plugs.

I was going through some of my car stuff today, and came across an original 1940 Ford owners manual/guide I purchased a few years ago; near the front, was a page dedicated to this thread topic--engine break-in.

It is interesting, the overview/recommendations for the 1940 Ford vehicles/engines; in the guide printed way back in in late 1939.

This is great! It's just as true today, as it was back then.
