Maybe I'm missing something. Are you sure 2500 mls is even necessary?
How many miles per year? How many trackdays? Is the engine still stock?
Did you have a UOA performed yet? Any other measures provided yet to
gain better engine reliability? What are your oil temps?
I'm not convinced if some particular special kind of oil is actually required.
Perhaps very most decently stout 5W-30/5W-40 would suffice and probably
any VW 511 00 & Porsche C40 should do. The picture still isn't clear though,
there's still a lack of data.

"Necessary" is relative I guess. I would like to get 2500-3k miles on an oil change tho, that way I'm not changing oil ever 9-10 tanks of gas.
It's a track car, not a daily driver, so the majority of mileage on this car is tracks, or driven VERY hard in the mountains/canyons. The only time this car is pulled out of the garage, when not being trailered to the track, is to be driven/tested in the mountains or canyons.
Internals are stock, but I'm pushing 30lbs of boost into it now. It has all the supporting mods needed (bigger intercooler, piping, radiator, oil cooler, etc, etc).
Yes, I have done a UOA, I posted it earlier in this thread. It was by Blackstone. The UOA came out very well, except for the shearing.
The oils temps are very low. In fact, Amsoil believes that I'm not getting th oil hot enough. 110* track days, and the oil never gets over 230*.....at most, and water temps stay at 215*. Just driving around normally, the oil temps are 175-188*, and water temps are only about 4* higher than that.
I don't think a "special" oil is required either. I'm just trying to find something that I can get 3k miles out of, and won't lose viscosity below a 30wt oil.
