Default How many of you followed the 2000 mile break in guideline?

After reading the following on another forum,

“When we do our engine test, the metals inside the engine never reach the temperatures they would when driven on the street since the test session is fairly short. In other words, the bearings, pistons and cylinders never get a chance to thermally expand to their maximum. Therefore, there is little wear on the moving components. But when you drive a car on the street, the engine parts expand considerably more because of the heat being generated from the engine running for an extended period of time. No matter how tight the tolerances are, there is always a slight amount of expansion in the material. The moving parts can wear quickly if exposed to excessive heat and not always in a uniform way. We also constantly vary the speed and allow the engine to run at both high and low RPM’s”.

“Porsche wants the engine to break-in slowly, which means it needs to maintain a lower operating temperature (below 4,000 RPM) and to allow all parts to adjust (wear-in) within their own thermal expansion parameters. This is also the reason why Porsche wants the owner to vary the RPM throughout the break-in period; therefore the engine doesn’t get use to one operating temperature range”.

“Porsche has been using Mobil 1 Oil since the early 90’s. With its superior lubricating properties, it takes many miles of driving (without getting the engine too hot) before the components actually seat (or break-in). Porsche’s own tests reveal that after 2,000 miles have been driven, all of the moving parts have had a chance to wear into their adjacent surfaces and then an increase in engine RPM is permissible.”

I feel more compelled to follow the break in process as outlined in the owners manual.

Curios to see how many followed it.

In Europe the break-in process is: drive the car without excessive load or engine speed until the oil is up to operating temperature and then drive it like you stole it.

I confirmed this procedure with the gentleman in Stuttgart who handed me my keys. The next day we were on the Autobahn.

IMO, the drive-it-like-a-granny USA-only break-in procedure comes from Porsche's lawyers who are still butt-hurt from the 930 lawsuits.

Let me be clear: That doesn't mean you're supposed to do launch control starts on the way out of the dealership. But, it does mean that you do not have to follow the by-the-book procedure religiously.

I mostly followed the break-in procedure but it was tough to restrain myself the first 2k miles.

I didn't do anything special to break mine in. I did take a long trip with the car as soon as I got it (therefore, I hit 2,000 miles very quickly). So the break-in was highway driving - nothing extreme, but probably not as much variety in rpm as some might like. My dealer told me -- do anything you like - no break-in of any kind required (although, getting oil up to temp as Worf says -- must be respected). I don't drive my car crazy hard anyway, but I didn't do much of anything special to break it in.

Yup pretty much under 4k for the first 2k miles. I looked at it if they Porsche recommended it could not hurt to follow it for the first 2k miles. Easy decision.

I'm doing my best to keep it under 4K for the first 2000 miles. Only 1,100 more to go!

The break in period is going to be painful. I have only 110 miles. I did push it a bit today as I was being repeatedly harassed by a Tesla P90D on the freeway

I think this is nonsense. I pushed the hell out of mine after a few hundred miles and would have had no issue with going to the track. I now have 12,500 miles after 18 months and haven't has a single service issue. Ferrari has started putting this in the manuals too and I ignore it as well. Tracked my 488 after 300 miles with no problems.

In May I went to the porsche experience center and drove the 17 911 turbo s. We did about eight launch controls and hammered on this car for almost two straight hours in hot and humid weather.

The car had 364 miles on it. I asked if they have any issues and was told none just regular maintenance, tires Etc.

I just test drove a 17 TTS and the CA insisted I do a LC. Car had less than 100 miles.

On my 16' TT, I did keep it under 4k for 2k except for once.

Revive this thread for any new car owners.

In my case, I'm not OC about the process. However oil temps need to be in the "normal operating range" before any spirited driving, but this holds true for Porsche at any mileage. No launches, no redline shifts, no lugging the engine at low RPM's for first 1000kms or so.

Opinions, thoughts?

Of course Capt. Obvious, but guys with fresh new cars need a starting point.

It's not like the 991 Turbo forum is booming with new owner's ideas and thoughts... other than site sponsors shilling product and services.
