Unless you do a 200-400 mile engine flush with Joe Gibbs BR30, you won't see any advantages of the DT40 till after your 2nd or 3rd oil change. DT40 just fights way too much with other oil's additive package. Especially Mobil's. The developer of this oil (Luke Speed of Joe Gibbs, and Jake Raby of Flat Six Innovations) will also tell you the same.
The best UOA's I've seen on my water cooled Porsches have come from Mobil 5W50. Second best was Red Line 5W40. I saw no better UOA's from DT40 than I did from Mobil 0W40. This is gleaned from over 100,000 miles and about 15 oil changes.
