The old CJ-4 formula M1 TDT and Delvac ESP showed the lowest metal wear numbers in my VW 1.9 ALH TDIs.
7500 miles (11 months) later - changed the oil. Then I forgot to get a sample.
This getting old stuff is taking some "getting use to"!
I could tell the injectors were getting a little cranky at startup when down in the 30's and 40's. Still - started up well (only a little rough running) and ran well within minutes of the startup.
Next oil change will get sampled!!! I've got a reminder set for November of 2022 (next 7500 mile mark).
Next fuel filter change set for November of 2023!

That looks real good. I've become a big fan of Mobil diesel oils. Their Delvac Extreme synthetic 15W-40 has given me stellar UOAs on my 250K mile 6.0. Iron never exceeds 7 ppm and it has a strong add pack...and over 1200 ppm of phosphorus to keep Ford Incorporated happy.
Many people will say the 6.0 'wants' a 30wt, but that is simply not true. You get much more headroom with a 40wt for shearing and dilution. Some of those 30wts will shear to a 20wt.

The viscosity is above a 30 weight, as you well know, but do you think it ended a bit on the thinner side of a 40 weight with under 5k miles? Obviously, this is to be expected on a 5w-40 just thought I would ask. I'm interested in these post's b/c I too run a 6.0L. I have less than half the miles so of course I'm at 3.16 ppm wear rate on just 2 oil analysis. Thanks for the post!
The wider the viscosity range (ie 5W40 vs 10W30), the more shearing you will typically get. Can't escape that process. That said, some 5W40's do shear faster than others - IMO it depends on the base oil. The Schaeffer 9000 sheared less than any other oil I tried.
Some people argue that shearing down to a 30 weight is SO bad, that they decide to start out with a 30 weight ..............
Kind of makes you go hmmmm ............ lol.
I do not doubt that I could have waited quite a bit longer for the oil change. I have been running 7500 mile OCI's for a while now, and have seen no issues. I went back to a (apprx) 5k OCI on this run simply because I just decided that I would change my oil AT LEAST annually. I didn't drive much in 2022!
When I go 7500 miles between oil changes, I typically end up on the high side of the 30 weight range. It is absolutely no big deal, and clearly it has nothing to do with what oil a 6.0L "prefers". It is a mechanical process acting upon the viscosity modifiers. Even though it will cause shearing in a 10W30 at a slower rate (and like a 40 wt, some 30 wt oils shear more quickly than others), that absolutely means nothing with regards to some people's conclusion that a 30 wt oil is better for a 6.0L.
I just watch the UOA results and it keeps me smiling.

Totally agree with you on the mindset of why not just start with a 30 weight instead of a 40 weight b/c it will shear anyway argument.
I have some 5w40 t6 in the truck now and am planning to do an annual change as well. However, this is my only vehicle so I should have some more miles and plan on posting the oil analysis results next fall. I'm thinking anywhere from 7500-9500 miles on the oil... we'll see. I think your 6.0l is wearing nicely!
