Getting some history on this engine now. Still a boring UOA so that's a good thing.
Silicon - a little high but the air filter has never been changed and the seal is still tight, I doubt any dirt is getting in. But I might still change the air filter, it's been 36K miles and almost 4 years after all. Maybe I also need to examine the the entire intake for a loose fitting or bolt(s).
Fuel dilution - from what I read here, Blackstone does not give really accurate fuel dilution data. But I will say that this is the thinnest used oil I've ever seen flow out of an engine. I did collect approx. 3.9 qts whereas it was filled with 3.75 qts, so there seems to be some physical proof of dilution occurring. And my wife even remarked about a gas smell in the garage.
Replaced with mostly the same PP 5W30 (3.5qt) and 0.25 qt of 0W20. I thought I had a couple of gallons of 5W30 in the garage but was mistaken so had to make do with this concoction. Looking at 6K miles for this ODI and leaning towards 0W20 for the next fill.
