I know this topic comes up a lot, but I'm curious to hear what people are actually doing after all the discussion clears... So, my question for those who bought their 991 new in the U.S., did you follow the break-in rules listed in the owners manual for the full 2,000 miles or not?

 

NTA!

 

Haven't people all said in these other 100 threads exactly what they do??

Is there a disadvantage to following the manufacturer break-in?? Some people have no self control.

What does Chuck911 recommend?

Anyway. Will make for some good entertainment

 

made it 1200 miles before first track day....

 

Some say, but many don't. People mostly just postulate about why the US rules differ; what they heard from the guy mopping the floor on a factory tour; what their saleman/head-tech/uncle/local machinist told them; how it's silly to second-guess the factory; how it's silly to follow US rules when you don't have to in Germany; what their conspiracy theory is for the origin of the rules; etc., etc. You can often surmise their answer (I'll assume you followed the book) but I was trying -- maybe unsuccessfully -- to bypass all the old discussions and just see what percentage of people do v. do not follow the book. I plan to follow the book regardless of what others are doing, but am genuinely curious if I'm in majority or, as a friend insists, I'm one of a few crazy suckers falling for Porsche's attempt to avoid warranty claims and increase car turn-over....

 

You started the same [stupid] thread on the 991 Turbo Forum YESTERDAY! Why another one today?

 

Because there are 313k posts on this forum and only 28k on the turbo forum, and it dawned on me that I could get more data asking a wider audience. I certainly didn't mean to upset anyone.

 

I'm following the German break in recommendations for my German car. Its what I did for my Cayman GTS, and what I am now doing for my 991.2 GTS:

" In the first 3000 km:
--longer driving distances preferred
--frequent cold starts with short drives to be avoided
--do not participate in track events, HPDE's etc
--avoid higher RPMs, especially with cold motor" (literally: "Hohe Drehzahlen, insbesondere bei kaeltem Motor, vermeiden"
The last is key, nothing about a hard and fast 4300RPM limit, use your judgement.

For me this means keeping RPMs below 4000 when cold, and gradually adding brief forays into higher RPMs as break in progresses, always once the engine oil temperature is out of the blue range. So under 4K RPM for the first 500 miles, 5K at 1000, 6K at 1500 miles etc.

So, you could say I'm following the book, but the German edition.

 

Take girl on first date ...

One has sex with you first date and blows you on way to dinner.

Other makes you wait a few months and exclusively dating.

Which one would you want to keep long term?

 

 

 

Brand new Porsche 15 minutes out of Stuttgart at 160 mph on the auto bahn. It took that long to warm up the oil. I followed the advice of the delivery specialist at the factory and the manual from all the other countries except the US manual. No shame in following the US manual though.....these cars are expensive!

38k miles later and no oil usage.

 

Drove it like I stole it.

Several drag races with another 911. Less than 200 on the odo

 

I recommend what Jake Raby actually does. So there.

 

Had 600 miles on my GTS today and went on a 200 mile pedal to the floor back road drive. Drove it like I stole it for sure.
