Because it's not formulated for track days. The temps get too high and the oil breaks down. I have used JG's racing oils like XP5 or XP6 with good results. This all comes from talks and directives from Jake Raby.

hellabuggin, your explanation is of someone else's preference. he may be knowledgeable but methinks Porsche engineers aren't any less so? so that means one independent has preference and so does the actual manufacturer. which includes engineers and scientists.
that still doesn't qualify your statement that Porsche's recommendation of mobil 1 has not a lot to do with it being right for the engine!
"Porsche uses mobil 1 for many reasons, it being best is far from the top of the list"

If you're happy with Mobile 1, enjoy it. Keep in mind that in 2005 Porsche also suggested you only change your oil every 20k miles. Was it for the betterment of the car?
Let's be honest, some guy on this forum who's sign in is "Hella-Buggin'" is in no way "damning to Porsche".

I personally have done UOA on Mobil 1 5W-40, Motul xcess 8100 5W-40, and Driven DT40 and in the non Driven samples, the TAN and TBN numbers showed breakdown of the anti-wear additive package and viscocity reduction in as few as 4,000 and 4,500 miles. The Mobil 1 was worse than the Motul, which was worse than the DT40. Also, keep in mind that using what's recommended in your 997.1 manual is 9-12 year old information, doesn't factor in advances that have been made in synthetic lubricants during that time, or government regulations that have made the oil companies reduce the levels of Zinc & Phosphorous in the mass produced oils. sygyzy, you can do what you like, but blindly following a lubricant recommendation for a sensitive engine such as the M96/M97 when there has been detailed lubricant and wear analysis done that clearly shows there are better options available seems like an uninformed way to go.

OK I want to put this nagging (to me) issue to bed:
Would someone post the oil bars at proper FULL and at 1/2 Qtr LOW?
I thought I read that FULL had one segment dark (unfilled) at top but after my Indy has returned the car on last two changes my ambient temp checks (pre-drive) show all bars lit. Am I full or overfilled?

If the entire window is full, that's overfull. The top half segment should be empty - it should only be full up to the arrow on the left side.
