This oil was run for over 9 months that included the entire winter, some of which was brutal. The truck does many trips of 2-7 miles (over the course of the oci). Some days it accumulates 40-70 miles over a few hours time. No highway cruising. Sometimes we go into Binghamton or Syracuse and do some city driving, but it's an insignificant portion of the miles.

No towing, but some hauling stuff in the bed. From a 750 pound ATV to a load of scrap metal (1700 lbs), but like the city driving, it's a small portion of the miles. It's driven gently, mostly below 1700 rpm. Maintaining 55 mph up 13% grades (even loaded with the ATV) requires a drop to 4th gear at 2300 rpm and that's as close to an Italian tune-up as it ever gets. No redline runs for me. smile

I replaced this oil with 5W-30 but as you can see, this oil had already thickened into a 30. And yup...the TAN over took the TBN.

I'm going to start using Milton Cat for all of my samples. The base price is $18.99 and the TBN/TAN are $8.xx each. I can drop samples at one of their locations and their parts delivery truck picks them up when making the rounds, and gets them to the lab. It's less stressful than mailing.

At shear-thickening of 10ish %, 10k metal wear rates is great with residual TBN of 2.3.
'High' TAN of 6.2 is of least concern.

Nice low wear; Fe still trending down slowly.
Contamination in control.
Crossover cautionary, but not causing an issue yet.

These are great wearing engines.


The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money

I'm a bit surprised that the oil thickened but as you noted, it's not a lot. At least it's not grossly out of grade. I don't have a VOA of this oil to get an accurate comparison, though. I have a VOA for the new oil that just went in so I can compare next time.

I'm not concerned about the TAN at all. I'm aware of the concerns about TBN/TAN inverting and indicating that the oil is spent, but I haven't seen a problem in my sample results when it happens.
