Chuck, thanks for posting your UOA history. I had very similar numbers to yours, but my oil change interval was more like 6,500 miles. I don't think you'll see major changes to your next UOA with the DT40. It will be the test after that (2nd run on the DT40) that you should see the most impact, once the DT40 gets permeated into the system at a higher % and you "wash out" the Mobil package. Jake has said (Lake, at Gibbs, confirmed) that the Mobil package and the Gibbs package fight each other in the beginning, that's why Jake likes to recommend a flush with the BR40 before the DT40.

I plan on running the DT40 in my new Carrera for a little while and observe the UOA's. I may then stay with it or move to the Mobil 5W50, which has given me great results in the past. Much like Redline 5W40 did.
