Well I don't necessarily think they're recommending Mobil 1 for everyone. Like they said, and we have seen here, there have been mixed results with that one, but improvement as of late.
The way I'm reading that, it's just that he's been using it previously and has apparently been getting better UOAs with it than with the Ultra so they're recommending he go back to Mobil1.

The 1st oil sample was from the car at 15k to 20k, and the 2nd sample was from 20k to 25.5k. At 15-20k, you are still at the end of break in so you would still potentially expect a slight decrease in wear metals.
Id have a smile on my face, nice UOA.

^Flashpoint is low..... probably a mistake. Looks great though.
I think once my engine is broken in Im going to use Ultra. Whats your driving style? You seem to put much more miles on your car than I do, are you getting stuck in stop and go traffic around DC or is it smooth sailing highway? Aggressive driver?

My current commute is from North Bethesda to BWI area. It's pretty smooth aside from the occasional traffic on 495. Semi-aggressive driving, enough to keep the engine happy.

Maybe not. Flashpoint is negatively impacted by fuel dilution. Blackstone Lab normally does a comparatively poor job of measuring/reporting fuel dilution. Here, they report 1.3% vs. < 0.5% the last 2 UOAs.
If fuel dilution was indeed high, the low wear metal count is all the more impressive. Most any oil will do a decent job in the absence of significant fuel dilution. One of the tricks of finding a good oil is one that will protect in the face of high fuel dilution.

Talked to LabStone and did some googling on the fuel dilution. A possible explanation may be due to excessive idling to warm up my car in the winter. I will try to idle for 1 min or less and see if it will go down in the next test.
