Dear all:
I am new here and finally got my 997.2, I am wondering how much km it takes to run in. Many thanks.

Welcome to Rennlist!

You'll find out that the break-in question is a rather controversial one... lots of heated arguments in the past:

Break-In Period
Break-In Period... Strict Adherence?

Thanks soulteacher. It really takes time to read them all.

On my '05 997.1 I followed the manual to the letter and never had any engine issues. In fact, for a total of 40,000 miles my total oil usage was less than 2 quarts. First quart was put in at about 2,500 miles and the next oil add was about half a quart at 37,000 miles.

Given that experience, I am following the manual again now while breaking in my new '09 997.2.

I followed the break in procedure that Louis at Zuffenhausen told me (under 5000 rpm for 2000 miles) and use oil all the time. It doesn't make a difference what you do.

I guess I'm not getting that part of the comment. Use oil as opposed to what? Sand?

Soulteacher

Consuming oil as opposed to not consuming oil (see Hole's comment).

Your joke and the context remind me of a weird question I once got on one of these stupid standardized tests:

Sand is to Oil as Glass is to _________

And 25 years later, I still don't know the effing answer.

Sand is to oil as glass is to PLASTIC

....sand is necessary to make glass as petroleum is necessary to make plastic

TP

Okay. But wouldn't it then have to read "Sand is to Glass as Oil is to Plastic"? See, I'm still confused.

Like. You. Stole it. lol

Table top? I'm at a loss.

I followed the manual for my 997.1. And changed oil and filter at the end of the break in. probably didn't need to change but did it anyway.

Do a road trip of 2000 mi.± for break-in.

Broke mine nicely for the first 100 miles, mostly on the way home. Then I took it to autocross and drove it ***** to the wall for about 20 runs over two days. Break it in the way you plan on driving it. Think about it. Are the cars used at the PDE babied for 1000 miles before being put on the track? Press cars? Porsche race cars? There are only 2 valid reasons for going easy for the first 1000 miles. 1, it lets you get used to the cars performance gradually. 2, if there is a warrenty issue it will happen at a lower power/limit level. One of the gentlemen at PCA told me that the 1000 mile break in will pay off somewhere near the 100,000 mile mark.

Warm up the engine and then test the rev limter daily.
