Wanted to share some results I got back today.
2007 Hummer H3 with 92K on the clock.
Just what the title says, let this thing go for a year, just to see what would be the results. Kept it full and let it ride.
Went a full year without an oil change, actually a year and 2 weeks and 14,120 miles with ~2 quarts added over the life span.
Running Pennzoil Platinum 5-30.

You'll be pleased to know that your engine and the oil handled the long
oil run just fine. Universal averages show typical wear after about 6,400 miles of oil use. You went 14,120 miles and still got average wear, so internal parts are getting along nicely. You'll notice sodium is high, but it's just a harmless additive in the oil, not coolant contamination. The viscosity was fine and no measurable contamination was found. Try going up to 16,000 miles next time and let's see how your engine handles that. Fantastic report!
