Another Break-in Thread...

My usual procedure is easy for till around 2k, oil/filter change at around 1k. As soon as the break-in is done, accelerate hard to redline whenever possible over the subsequent drives.
I done this and never had a need to add oil between changes to my cars. I also will accelerate hard on a regular basis. The engine does feel more alive now with 14k miles.
What it boils down to is this, I'll do what I want in my car, you can do what you want with your car.

Now in my first week of ownership I get why it’s so tempting to forget about any form of break-in and just drive it. It’s like when a plutonic female friend made me promise to wait 10 dates before getting it on with my current gf. I got seduced on the third date.

Platonic is what you meant, related to Plato from way back when, same as the name Pluto.

The powers of seduction. BTW, if you have a plutonic female friend, she's must be hard to be around, 'cause Pluto is the mythological god of the underworld, anybody who's plutonic may raise heII!

I always see the notion of a break-in period being specified in the manual because the "lawyers want it in there" thrown around in threads like this (not just a Porsche forum thing). Theory being that Johnny Racer floors the car right off the lot, doesnt realize how powerful it is, crashes the car and then sues the manufacturer for not warning him of the dangers. This make absolutely no sense to me from a rational standpoint. Aside from a lawsuit like that have probably 0% chance of being successful, the break-in procedure is fully centered around the mechanical components and not the skill of the driver. If Johnny Racer crashed his car, would the break-in language somehow absolve the manufacturer from liability? What does mechanical break-in have anything to do with driver skill and caution? Also, do you think the average person reads their owners manual from cover to cover and that there is a reasonable expectation for a buyer to do so? If Johnny Racer needs to be protected from his own stupidity, wouldnt the manufacturer put a much more stark and noticeable warning somewhere instead of burying it in the owners manual under the guise of a mechanical break-in?
Sorry for the rant, but every time I see the "lawyers want it in there" argument I am always baffled as to what a silly notion that is.
But anyway, I am with those saying to follow the owners manual. Porsche obviously has a reason for spelling out a specific break-in procedure (and it has nothing to do with absurd law suits) so you may as well listen to them.

Its 1) a liability reduction method, 2) a get you familiar with your car method and 3) considers that you also have new brakes, a new differential, and a new transmission.
In terms of the engine revs, warm it up at low revs then do what you want. The whole "its gonna be so tight that it overheats" is bs. Ive built several motors and broke them in either on the dyno or racetrack. All made excellent power for the combo and did well on oil consumption.
For those that believe the manual is right, what are the parts that will fail from a "hard break in"?

Reason they don’t know why they taking it easy for 500/1000/3000 miles or whatever is because generally people don’t know what break-in actually means. If they did they’d also understand it’s unnecessary.

I did PEC Atlanta when they opened and I did drive 718 S , GT3 and 911 Turbo, all had less than 1 k miles on them
and instructors were encouraging me to push as I hard as I can
we did have some extra time and I remember launching the 718 S like 20 times a row , and the instructor kept asking me if I want to do more .

Nobody knows. People breaking in cars same way grandpa did but no one knows why. 😂

Really, the biggest determinate of engine life (assuming good maintenance and proper assembly) is ring seal. Cars with poor ring seal put more contaminates into the oil, generates more carbon build up, and make less power. By applying some cylinder pressure, load, and then vacuum (letting off at high rpm) when the engine is new, you are promoting good ring seal. The often quoted motoman website describes this well. So the argument that race engines will be short lived if broken in hard is crap...they will run longer, burn less oil, and make more power.
For the average street car, this mostly makes no difference...but the argument that you are damaging an engine by giving it some load and revs when new is just wrong.

Are these statements there because lawyers recommend them? Who really knows, they’re hardly going to say so. All we do know is that they originally started appearing in US only owners manuals some years back and the rest of the world looks at that and says ‘well, that’s America for you’. Either way you’re not going to get a warranty claim declined because you revved the engine to 7000rpm on day one. Your lawyer will see to that.

So after I got my car I've been breaking it in gradually....
did 100mph first, 110 next, followed by 120 and then 140
by this time I was probably up to 800ish miles, I hit 165 twice around 1k but haven't tried since, I do believe I was limited by not having broken in the car enough to get above 165
conclusion: break in period might be real
