This engine has been on Kendall semi-synthetic oil since the first change. The change interval is one year due to relatively low annual mileage. The last two oil changes used the "new improved" formula without Ti. Looking at the wear numbers, it didn't effect wear one bit. In fact, wear metals are down to virtually nothing.
The RV forums are filled with people who have to run V-10s on Mobil 1 and change it every 5,000 miles or sooner. While ExxonMobil thanks you, your V-10 couldn't care less. It's about the numbers.
 
I have a Coach House 272 xl. That the previous owner used Mobil 1 in. It has 57k on it and it is a 2005. Looks clean as new on the stick and uses no oil. I plan to change it before putting it in storage for the winter. I see no need to get more fussy about it than that.

The V-10 is a remarkable engine. Mine sits for up to six months at a time and the UOAs are proof that sitting causes no abnormal wear. U-Haul has hundreds of them (if not thousands) that are largely driven by people who know nothing about trucks or engines and don't care about the trucks.. They seem to hold up just fine.

AITG,

Is your 6.8L V10 the 2 valve or 3 valve motor?
 
Three valve. The fuel dilution puzzles me. I did switch to 5W-30 about the second or third oil change but it never sees cold weather operation.

Could be bad injectors
It's been that way from day 1. Dealer checked fuel trim numbers and they are good. Runs great, good mileage (for a V-10). Without UOA I wouldn't know.

Since the issue is fairly static (repeatable), I’d keep the same usage, mileage, & OCI pattern and skip the UOA. They kinda lose their value once you’ve determined that the oil is still serviceable when you drain it.

Actually, I used to have a fleet of about 100 diesel tractors and 150 refrigerated trailers. Everything that was lubricated got UOA every time it was drained. I found oil coolers that were starting to leak, air intake leaks, and wear metals that suddenly started to increase. If I waited until the problem was visible to the naked eye I would have lost a lot of engines.
In my own vehicles, UOAs, every single drain. If you don't build a history, you can't see abnormalities.

I do agree that fuel dilution is an occurrence and not necessarily a problem. Manufacturers are building hundreds of thousands of DI engines. I imagine fuel dilution is occurring in all of them but nobody checks. Ford recommends 5W-30 in their turbo engines, 5W-20 in naturally aspirated engines...probably to compensate for fuel dilution (only a guess on my part).
