Curiosity killed the cat. Hopefully it won’t kill my 10R140, because for some reason (Valvoline was out of stock) I decided to buy enough of the stuff to drain and fill twice with a PPE transmission pan. Will test at 1000 miles and will try to remember to report back. Fingers crossed.

In typical Triax fashion, the product description, specifications and properties vary significantly from one place to the next. On their product page, they list it as an API CI-4 with a TBN of 15. On their PDS, they list it as an API CF-4 with a TBN of 10. The VOA looks fairly standard but as...

VOA for Triax STOU 10w-30. Marketed as an all purpose GL-4 trans-hydraulic, hydraulic and CF-4 engine lubricant. Claims to meet a number of specifications for equipment requiring a higher viscosity than would be found in the majority of universal tractor fluids.

VOA for Triax ULV ATF.

The Rotella 15w-40 had actually sheared down to about 12.5 cst @ 100° (with a small amount of fuel dilution per Blackstone’s calculations). But no, I don’t credit the oil change with the entire 2mpg, it just makes me feel better about paying twice as much for oil. Factors like a new air filter...

I’ve got a ‘22 6.7. In my experience, people with ‘19 and earlier engines will report different findings with different oils (T6 5w-40 solves typewriter noise, doesn’t produce abysmal UOAs, etc) than those of us with ‘20-up engines. @RDY4WAR hit the nail on the head. I’ve done 5000 mile OCIs...

I’ve been searching this forum on an almost-weekly basis for the last five years but I never came across this thread. I’m guessing there are plenty of people in the same boat as OP. I finally created an account to post a few new VOAs but figured I’d keep this thread going with my two cents. My...
