Thanks for the insight. I’ve always been fascinated with the use of mo and sb in lubricants, especially high levels found in RLI and HPL formulations, respectively. I chose to use this amount of RLI’s Booster Pak, as opposed to the significantly higher labeled rate, based on the amount of sb...

I have a third run on this blend in this engine as we speak, I’m going to take it out to 150 hours and see how it performs. I have concerns, but the wear protection is phenomenal. From a bit of research on the subject, my theory is that any issues the DPF might have with the Sb and marginally...

For comparison, here is a Blackstone report with two additional used oil analysis of the same machine. The older UOA Rotella T6 5w-40, the newer is Rotella T6 15w-40. There are some issues with Blackstone, the most obvious one in this report is the viscosity of the T6 15w-40, which I believe is...

Attached is a VOA for a 2021 John Deere 333G equipped with an unmodified 100-hp Yanmar 4-cylinder turbodiesel. The homebrew blend used was 11 quarts of Schaeffer’s 700 Durability Advantage 15w-40 with one quart of Schaeffer’s 9001 5w-50 full synthetic race oil and 3 ounces of RLI Bio-SynXtra...

I’ve been daily driving diesels for a good chunk of my adult life and I’ve been fortunate enough to have only gelled up once. That happened following coldest night of the year (I think it was about -5 F at the time) running 100% #2 treated with OptiLube Winter (with the high treat rate of about...

Changed the gear oil in two of my trucks this week. 2022 F350 6.7 4x4, installed PPE covers on both axles and changed the factory fluid at 35k. -Front Dana 60 (limited slip) got 3.25 quarts of Valvoline Advanced 75w-90 with 3 ounces of XL-3. -Rear Dana M275 got 4.5 quarts of Schaeffer’s Extreme...

I’ve been curious about the chemical composition (and potential chemical incompatibilities) of LV and ULV ATFs, along with other fluids I’ve started using more in recent years (like a number of Red Line products and HPL Differential Life). I recently found myself more or less stuck with 8...

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 10w30. 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.

used oil analysis from hydraulics on 2021 Deere 333G high flow (~9 gal capacity). Factory fill Hydrau XR AW46 (I believe a full synthetic). In the first few months I owned it, 3-4 fittings came loose and a few hoses had to be replaced (gotta love Covid-era quality control), ended up having to...

The Rotella 15w40 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 used oil analysis, etc) than those of us with ‘20-up engines. @RDY4WAR hit the nail on the head. I’ve done 5000...

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...
