There’s a reason why the machines in HPL’s or any good oil testing lab runs well into 7 figures for the combined machines- getting good, relevant data is not cheap! But then again, neither is replacing failed engines^^^ Sometimes knowledge will come at a cost.
Anything that’s used for half of its rated life should look great.
@Linctex ran a plain Motorcraft for over 50k miles… now that’s intestinal fortitude!
It’s been so long that the legend had grown… 30k on Motorcraft is still a leap of faithThat FL-1A was on for 30,000 miles. Ford 400 2-bbl in a F250.
Looked great when I cut it open. . . . . . That was around 1995 IIRC....

The "50,000 mile filter" was a Fram Tough Guard

The "50,000 mile filter" was a Fram Tough Guard - - - 2008 F150 with 4.6 2V engine.

Noted. Do we know why?Car runs better with new filter and fresh oil. This should be noted.
I'm thinking maybe TBN was depleted or about depleted. I really wanted to get a non-Blackstone UOA.Noted. Do we know why?
Unless the acids in the oil are dissolving components in the engine, it’s dubious that TBN reduction is the cause. It’s a chemical buffering function, not a viscous/mechanical issue. To say the oil was sheared down may be a cause but you’re running HPL oil IIRC, which should be pretty stable. I suspect it’s another engine issue, either from something going bad with age, or from tinkering.I'm thinking maybe TBN was depleted or about depleted. I really wanted to get a non-Blackstone UOA.
I want to run this oil out for the long haul, as well. Since I insist on doing it myself...

I doubt that the old school Taurus v6 is that hard on oil or that even a more generic oil like cam 2 wouldn’t be up to the task for that engine. This is where a UOA would be helpful to see if the oil viscosity held, if theee was fuel dilution, etc.The Taurus didn't have HPL in it.
The Taurus had CAM2 5W-20.. an ILSAC GF-6A (said so on the quarts.)
The Subaru had HPL... I apologize, I should have clarified.
Maybe that OCI was a tad long on a regular old 5W-20.. I should really do more "controlled" tests/documentation.

TBH I don’t know. I used to use Napa but I think the last few weren’t run, I never got results.I think you're on to something!
What's a good UOA that's not Blackstone that I could perhaps do better "controlled tests" as to length of OCI and remaining TBN? That seems like it could be relevant.
I should keep better track of those things. They seem relevant.
