I do it for "best working practice" and it costs very little to do anyway.

I agree. I also open the line out of the oil pumps on each cam tower just to see if the valve train is OK

Is it just habbit or a random sense of piece of mind? As I said, I too am considering changing it early, but i was thinking about 8k to 10k miles, rather than 15k, and I have no good reason for why 15k is too many when Porsche says its ok. Who's asked thier Porsche service guys about this? I DIY my oil, but if you have Porsche do it, do they really schedule you in at 15k miles?

I am probably on the paranoid side, but all a manufacturer really cares about is getting you out of the warranty period....

larry47us is infamous around these parts

I change my oil every 5,000 miles. I also drain the turbos. What's the additional expense of draining the turbos? Two crush washers and maybe another quart of oil. Compare that to the cost of the engine. I never understood why people are so concerned about stretching the time between oil changes.

If you really want to know the ins and outs of your oil, use an independent lab to analyze the oil when you do a change, or drain off a little of the oil and send it out for analysis to a shop like Blackstone before you do the change. They will tell you if you can wait longer to get your oil changed, tell you what metal components are in the oil, (which will tell you how your engine is wearing) and the amount of additives that are left.

The cost of the test is about $25. Lots cheaper than an oil change.

I wouldn't wait that long to change my oil. The oil gets all the sludge, metal particles, acid build-up, moisture build-up, and it just keeps circulating that stuff throughout the engine. No matter how many miles you put on your car, I wouldn't wait longer than a year to change the oil. You have one of the most expensive sports cars made, and you are scrimping on changing the oil? Bad economy. Penny wise and dollar foolish. But it's just my 2 cents. It's your engine. If you doubt the wisdom of what I'm saying, ask your mechanic how he feels about your waiting 2 years between oil changes. Yeeeccccchh.
