Somewhat disappointing additive levels here (despite the stated trend in that direction). I was a devoted user of Supertech oil but current pricing.and what appears to be a relatively weak add pack convinces me that there are better choices at this point. .Is the same thing happening to the other iterations of this oil (Amazon Basics, etc )?

Because I asked Blackstone to re-test the sample I sent in. It was off by that amount. Which was about 0.7cst.
So if it was off the first time, the second time is going to be correct just because they retested it? Viscosity testing is not like a broken clock, where it’s right twice per day…
They could avg the two to get a better number. just a suggestion.
IMO, it’s much better to simply drive the car gently until warmed up rather than letting it idle. DI engines seem to hate cold idling and it may be contributing to your presumed fuel dilution issue.
Not my video, but.......
The ADBV holds some oil back on the dirty side, but the clean side fully drains. This is why I run a Baxter adaptor on mine. It's basically an adaptor that is an anti-siphon valve that keeps the filter and oil galleys full of oil at all times. One must use compressed air to evacuate the filter before spinning it off or you will have a -big- mess when you spin it off. The adaptor has a Schrader valve solely for this purpose.
