Flawed logic. Your reasoning applies to both sides of the user spectrum - while some "baby" their cars, other mechanically tone deaf owners would be redlining their car from day one if not told otherwise. What Porsche does makes perfect sense.

Lol. Love to see you disclose that in the ad

when you try to sell it



Seriously, why WOULDN’T one follow the break in advice, take it easy for 1000 miles and at least bed in the rings? What exactly is the benefit in nailing it straight out of the box? How does thrashing the nuts off it from mile one extend engine life and reliability? Anyone?…

Because I can’t drive this car slow. At least not for 1000 miles. It is pure misery for me.

Of course, judging by all of the people who I see out there driving 911s and Corvettes slowly to the golf course or who never drive it but simply wash & wax 5 times per week in the garage, I’m obviously in the minority among performance car owners.

BondJ

Lol. Fair enough, but that’s just you not-giving-a-****. Doesn’t answer my question…

So we're clear, taking it easy does not bed the piston rings. The way to do this properly has been covered in this thread already. Those of you that babied your cars for break in and are now living with oil consumption are the proof.

There might be other bits and bobs that benefit from staying under 4k for a couple thousand miles. Piston rings are not it.

I've never had a single problem with my approach; let it warm up, and drive it like you stole it. This approximates what others do more deliberately, running through the rpm range once warmed up, etc.

BondJ

So, no need to bed in the rings, to take off the high spots and improve surface finish to assist bore seal and reduce oil consumption later in the engine’s life, eh? BS.
You may have had no problems with your car ‘driving it like you stole it’…but I’m betting the next poor sod to own it does!

Why would one assume that?

It does not necessarily follow that an engine benefits from being kept below 4k RPM for X number of miles. Do you have metallurgical or mechanical studies to show that?

ipse dixit

This is so damn ******* true.

In fact, taking it easy is probably one of the worst ways to seat the rings (assuming the rings need to be seated).

For the 100th time... who cares! If you're asking it's because you think 1875 Miles is too long and are answer shopping for a shorter break-in time. I waited 600 miles (I000 KM) before really opening It up. And waited the full 1875 miles before doing a launch. I feel comfortable with that.

BondJ

They don’t need seating, they spin on the piston. Because of this they need sealing to the bore (removing high spots). Not over-extending RPM when new assists this process.

Yep, to me there's only 2 things you can really influence during so-called 'break in'. The brakes and the rings. Brakes you fix with a couple of decent stops on the way home from the dealer. Rings you fix by leaning on the gas pedal at mid-revs a few times, to load them up a bit. Maybe I'm just old school and don't like dealing with lawyers.

OP - so there you have it - a crystal clear break-in process embedded somewhere in this thread. Any other questions?

I kept it under 4K for 4K miles (I'm at 3,999.x) due to severe temperature differences, I'm not idling for 20 minutes to get it up to operating temperatures.

As soon as I clear 4k at the end of my driveway no doubt and the 3 miles of gravel, I'm letting her rip.

Not a single drop of oil consumption. And yes, it is driven year round from 82F today to -38F this past winter in snow, slush, mud and dry pavement. For anything else I have my Touareg

Not scientific in any way, but the BMW V8 owners who aggressively broke their cars in, seemed to have fewer issues with oil consumption over the life of the car.

as I have said, I’ve seen plenty of people have issues with cars babied from the get go, just not the other way around.

and seriously, these threads are fun.

What we have is 2 sides and both sides make their arguments. Pick which side you are and follow the instructions 😆

I’m wondering how “broken” in are all the cars we see the journalists drive soon as the car hits the public? They do a swell job of staying under 4k to showcase the cars👍🏻
