My most recent oil analysis is attached. Was changed with the oil life monitor around 11% or 6.5k miles. 0W-40 Supercar has been used since the engine was new.

Blackstone is telling me that changing oil at 0% oil life would be fine given the health of my oil at each change. Granted, I'm changing oil every 3-4 months given my daily driving habits.

If I wasn't driving it much, i'd change the oil annually, after every winter, due to condensation of water vapor in cold temps.

I would NOT push it If you're doing anything other than cruising around. At that 100C viscosity you're already in the middle of a 30 weight viscosity (9.3 to 12.2). Additionally, you don't want to go below 2 TBN, the detergency of the oil starts to drop fairly quick after that.

Wear metals look great though.

Agreed. I see the oil life monitor as a relative limit. It's good to see how the replacement engine has worn-in and the absence of foreign and undesirable liquids is good. While Blackstone has their objective opinion, I have no intent on pushing past 10% and as I approach 10%, driving habits become pretty tame.
