Don't worry about what you oil analysis says, change the oil at 5000 miles or sooner on the 6.0l and you will be fine.
I tow an 11000# trailer year round on 5w40, and that includes numerous trips over the Sierras (sea level to 9200 ft) and have had no oil related problems. What makes you think the 5w40 oil would shear to a lower viscosity than the dino oil?
Don't worry about the oil analysis.... I like that. Kind of like sticking my head in the sand.
I had Pb going up in all of my analysis and then at 12k miles, I lost a Turbo. After new turbo put on, Pb went back down and no more issues. How can you say not to pay attention to oil analysis.
Have you done an oil analysis to check what weight your oil is at after 5000 miles? That would make me nervous.

This is a "heavy duty" truck with a roughly $15,000 motor, I'm not going to risk damage to save a couple of bucks on the filters.
I've had mine since 2005, it has 120,000 miles and almost no problems (or modifications). My mechanic is a fleet mechanic who works on ONLY the Ford 6.0. I am following his recommendation here.
I have confirmed the OEM rotors and pads are better after paying for and chewing up Napa Gold pads and rotors in less than 15,000 miles. I'm back to the OEM ones now.
I do love the truck, tows even my trailer with ease.
Since free oil and filters are a job perk I change my oil every 3500 miles so no I have never checked the viscocity or anything else for that matter. Have you ever run 5W40 and done an OA on it or is your condemnation of the product based on internet myth. So you had Pb in your oil, did the OA tell you what component was failing be for it failed? No, so what good is the info. Unless you have a fleet and are trying to save on maintanence costs OA is overkill. Oil is cheap, the 6.0l demands a lot of it, changing it often is cheap insurance.
I should add that in addition to owning a 6.0L I also work on them. None of the fleets we service,or regular customers for that matter use OA. Just change the oil every 5000 miles or sooner and you will be fine.

You sound like another guy on a forum that is upset his new 6.7L starts a regen 1 mile from his house. He expects it to start sooner......... How would an OA tell you what component is going to fail, that is silly even thinking that.
I will be doing an OA on the 5W40 that is in my 6.7L at the next oil change. I'm not condeming the oil, I am saying what most folks use in the PSD, 15W40, and I am stating that the viscosity breaks down quickly from the OA. Those are facts, not internet myths.
If you change your oil every 3500 miles, why are you telling folks to go 5000 miles...... You should at least try to keep your stories straight.

People think that by using synthetic or doing an OA they can extend the service intervals. Don't do it! Like I said above no more than 5000 miles between services, or sooner on the 6.0L.
So the oil breaks down to a 30wt, big deal all oil breaks down, 30wt will adequately protect the engine. I am sure in the 30 and 60 hour stationary engine viscosity testing done by Ford and International the rate of breakdown was taken into account in spec'ing the service intervals and lubricant requirements. I can assure you that there are hundreds of thousands plus of 6.0L owners that are not doing OA and their engines are doing just fine. Just drive the truck and stop worrying about what is going to break.

I would run 15W40 in the 6.0L.
What kind of EOT's are you seeing??? I have seen over 250* towing a little 30'er. That was my main reason for switching to syn.
Still waiting to see the links from the threads on Dieselstop- Im over there more than here and most of regular posters on the 6.0 forums all recommend running the T6......
Shell Rotella® T6 provides extra protection against breakdown by heat and offers up to 70% better oxidation resistance, compared to conventional Shell Rotella® T3 15W-40 API CJ-4 oil. Shell Rotella® T6 5W-40 provides excellent low-temperature flow, even at -30ºF.
MAINTENANCE SAVINGS
At lower temperatures, using Shell Rotella® T6 5W-40 can help your engine start more easily than using a 15W-40 viscosity- grade product.
Shell Rotella® T6 5W-40 can help protect the durability of the starter and battery in harsh winter climates.
UNSURPASSED SHEAR STABILITY
Shell Rotella® T6 5W-40 provides unsurpassed protection against shear-stability degradation, compared to the leading competitive API CJ-4 5W-40 products. An extremely shear-stable product helps maintain consistent viscosity and oil pressure in the engine.
