I've heard that also, I know for a fact that High Performance engines are broken in the same way by using standard oil rather than synthetic oils. I think it goes like this:

1000 miles Change oil and Filter
1000 more miles change oil and filter

Then use synthetic and change oil in regular intervals.

While I am no expert, I have heard that it's not good to go from synthetic to mineral to synthetic oils.

So, the factory filled Mobil 1 is sythetic and you're going to go to mineral and then back again?

I've heard that myth also but it isnt true, The engine is a machine and switching oils from normal oil to synthetic have any ill affects on the motor.

The reason you use regular non-synthetic oils for break-in is cause the standard oils aid in getting the bearings, piston rings and other oil lubricated parts to set into there groves...I think synthetic isnt used in high power application break-ins mainly cause it protects internal engine parts so well that it would take a very very very long time for the engine to break in and the piston rings wont sit well enough in there sleeves.

Why not just follow what Porsche says in the owners manual? Or do you think they know nothing about engines??

Probably a good idea.

Nope not me, I will not leave that factory fill Mobil 1 for 20 K miles regardless. But that's about it for me differing with the owners manual.

I have followed the factory break in pretty religiously for the first 2k miles. Did pop it up to 5 k 5.5 K a couple of times but not much at all.

Car is now approaching 3k miles. The last 1000 have been a blast. Wow different car and I was throughly enjoying the car during the break in.

First real exercise was this last Sunday Palomar Mtn. South grade road just an up and down.

Last time I was up to the telescope was in my 928S4 a couple of years ago. That was fun! The Boxster was very close to a religious experience. It is a great road, traffic was light, beautiful 90 degree day top down. And I ditched my beautiful wife at the casino so no noises from the passenger seat!

Porsche, There is No Substitute.
