From manual on "My Porsche" app:

Safety and Driving pleasure > Before driving: important information regarding your Porsche > second headline after "make yourself comfortable in the driver seat" is "running in the vehicle". That's where the screenshot came from.

It's not only the engine being broken-in. All the other stuff creating this great ride needs time to settle in too.

Thank you! This is what I was looking for. Much appreciated.

I was once told the transmission actually is more sensitive to break-in than the engine. Whether that is true or not I'm not sure but it actually makes a lot of sense to me.

ron4sc

well said. Or said another way, “if you lease, you won’t have the car long enough to know if you were right or wrong; if you bought it, follow the manual.”

My car just went over 1800mi, so I don't worry about it anymore.

Is it strange that there is documentation and we still get these questions? Maybe not, but rather it’s sorta endemic of things in America where everyone does and believes in what they want and what they believe is right based on their truth, Interesting world we live in these days.

Except that there are no references to break in guidance in other countries. So only cars in america need a break in?

Probably a good guide, but need to remember that the GTs as designed to rev much higher than the turbo engines.

Is that actually true or is that an internet rumor? I would be surprised if there was no run in guidance elsewhere.

Having lived the first few decades of my life abroad, I find Americans less willing to subserviate to rules unquestioningly and more apt to ask why to authority. It's not a bad thing. In some countries where I have lived if you stuck a sign in the town square that said form a line, within 15 minutes there would be a line in front of the sign. That must be why I am following the break-in recommendations

Now, this makes perfect sense! ALWAYS warm engine up, drive normally for a few minutes (at least) after each cold start to get all fluids to temp. Then, just don't beat the **** out of the car during break-in. After break-in, still ALWAYS warm car up before flogging, but after that, it's party time.

The original author of this post testified that this was the word from Andy himself.

@Staffie Guy true, so one could go a little easier than these RPM's.

I think the key is that you don't have to keep it under 4k RPM for 1,800 miles. As the Corvette engineers stated in the Savage Geese video (where we can WATCH THEM FOR OURSELVES rather than read about it on the internet - I'm personally glad about that) and they state that mostly it's important to vary RPMs, MPH, and to be careful with engine temps. Avoid short trips. And don't track it until broken in.

My GT350 gave VERY detailed engine break-in instructions in the GT350 Owners Manual Supplement. It basically said to make sure the engine is fully warmed up each time you drive it. And to drive gently for the first 300 miles, then harder up to 500 but not full throttle, then quite a bit harder up to 1,000 but yet no track time until 1,000 miles. It was even more specific, but that's the general idea.

Biggest takeaways:
1. If you can't take the car for at least a 20 minute drive, don't start it at all.
2. Vary RPM, MPH and load.
3. Avoid long full throttle pulls.
4. AVOIDE LUGGING THE ENGINE (ie, driving with RPMs too low is potentially MORE damaging than too high).
5. Change the oil at around 1,000 miles or so, AND THEN let her rip!

Oh, and items #1 & 4 above are very good long term practices to live by. Even if it's a lease, because your current dream Porsche is someone else's future dream Porsche.

Soap box dismount.

Or, OR... you could follow what Porsche put in print and not bother speculating as to what one could do based on testimony of some dude that spoke to another informed cat. But as we have seen in these threads over and over and over again, people will do what they want...and that's why I wanted a new GTS.
