Not sure where to send you for the sheets you're looking for. I started using Driven DT40 in my 997s based on the recommendation of Jake Raby with FSI who used it in all his rebuilt motors and tested it extensively. Then started using it in other vehicles I had that needed a 5w40 spec oil. When I started comparing the UOA reports from the Driven oils to those from everything else I'd run previously (Motul, Shell Rotella, Mobil 1, etc) it became apparent how much better the Driven was at lowering metal wear ppm numbers and maintaining it's viscosity, so I don't really care what's in it, just what it does. I have never seen a UOA report on another Cayenne that is better than the DT40 ones from my modified 650 HP Cayenne Turbo S. This year I switched it to DI40 since it's a DFI motor and hope the results are as good as they were with DT40 but won't have the first report until next year and it also really takes 2 before you can see the difference so that's a ways off on a car that only sees 4-5k miles/year.

I now use only Driven lubricants in all 9 of my vehicles - differentials, transmissions, engines, etc selecting the correct Driven product for the application. The one exception is that I still have MobilLube PTX in my 997 manual transmissions as that seems to work extremely well and I recently changed it so no need to change it again. I probably go through 8 cases of oil per year from Driven and usually buy it during their holiday sales.

If you're looking for a Cayenne UOA history to use as a benchmark for comparison, here is mine - 1st report was the Mobil 1 0w40 European Formula that was in the car from the last dealer service when I bought it. All the subsequent ones are DT40.

Yes, I have heard about the Driven oils on the other Porsche Forums, Charles Navarro, Lake Speed Jr, etc recommending them, and have been tempted cause they usually have DT40 at Summit as you mentioned Petza, right there starring at me on the shelf.
Ive used RL before and in my others cars, so naturally went there 1st for what I consider a top tier oil.
I also just added a FVD Brombacher tune to get me 510 hp so figured I should run the best oil I can.
Ill try the RL for a few OCI's, maybe the 5W40 version, then see how it goes, and then try DT40.

HPL also sounds like a great oil, from what I have seen on Bitog forums, and Lake's recent youtube video at their test facility. I used their 40 wt cleaner oil in my previous OCI in an attempt to proactively clean the ring lands to avoid bore scoring (which can happen when rings get stuck due to carbon build up on the very weak rings used these days). They will be my 3rd option after RL, DT40, as they are just as expensive + shipping since its not locally available.
