IOLM at 40% but last year I ran it down and ended up changing the oil in February: below freezing in the garage and the truck dripped all the time I was under it. I happily gave up oil life to change it on a 75 degree day.
It appears that Kendall had tweaked their LiquiTech formula. The last two changes were evidently the latest version. It has returned to Titanium, lowered the Moly, raised the magnesium and cut calcium even further. Looking at wear metals, everything is rock bottom. The engine doesn't care.

Nice report

Even your longer drain intervals were good results.

Loaded with fuel.

More than I'd like to see but it isn't showing up as engine wear...yet. The whole direct injection/fuel dilution issue is controversial. Is it a problem or an occurrence? For the record, Kendall 5W-20 (the recommended grade) has a published viscosity at 100 degrees of 8.8. The sample is 5W-30 and the sample vis. is 9.2.

I thought about so many times going with the Kendall GT1 on my '17 5.0 and never did it, not sure why. Looks like a great choice.
