Ditto-Red Line and AMSOIL. The DOES get dirty, however, their is no disputing that SYN is good stuff.
RE: the 7500, I simply don't feel OK on the 20K but it is my personal preference more than anything. However, you should know that Porsche replaces more than their fair share of engines. And if you are out of warranty, why chance the engine going south over the cost of an oil change?

No... Any new car should be able to go 200k with regular oil changes, synthetic or not, if it's cared for properly. This was a car that was run 200k with NO oil changes between. I actually may still have the article somewhere, I can try to find it. Am I suggesting you go 200k between oil changes? No -- just stating that the slow shift over the last several years from 3k to 15-20k may not be as big a deal as some people are suggesting. And from a guy who has changed his own oil since he was 16, I will say that whether it's as clean as new or not, it LOOKS clean. It doesn't form that black thick sludge like dino oil. It stays yellow and clear.
I'm ok with personal preference, but I just think that a lot of car guys have a hard time breaking the mold that we grew up on -- 3k dino changes. If we applied the same stubborness to other areas of our cars, we'd all be running redline tires on 16" steel rims, upgrading our carbeurators, and adjusting our timing every time we change the oil.
Both cars and oil have made huge progress in the last several years. So why, then, can't we accept that the two would work together in harmony longer than they used to?
