Continued use in my diesel engines whether my Superduty pickups or my Kubota tractors etc. Lab analysis consistently indicates superior performance results, and life of the engines.

The oil is of very high quality compared to other oils of the same grade. Our truck runs smoother and quieter. Most importantly we have the fuel mileage return to new truck mileage. Our truck brand new averaged 1150 - 1200 miles per fill up. Overtime we saw mileage go down to 980 - 1000 using Semisynthetic oil. I am very satisfied with products from TRIAX and I highly recommend them.

Delivered easy, fast, and leak free. For 5 gallons, they used to use buckets, which I guess might have issues with leaks during delivery, but they are also easier to reuse/recycle for other uses (something I preferred). These new containers are leak proof and easy pour, but hard to recycle/reuse. Not a dealbreaker. The oil is high quality makes the machines purr.

Started using Triax for all trucks last year. Been happy with performance and results.

I put it in my 2018 F250 6.7 powerstoke, engine does seem to be quieter haven't driven much since oil change milage appears to be better will update after some longer trips.

My 2018 GMC Duramax likes it

quiets them down

Works perfect for my 14KW Kubota generator. Also use it on a 4 cylinder turbo Duetz diesel engine & they both run super smooth & quite!

After trying multiple brands of Synthetic oil I ran across Triax. I used both 5w 40 and 10W 30. Both ran great but the engine noise was lowered with 10w 30. I run it all year long as I live in Florida. The oil is compliant to ford specs for the powerstroke, cost effective, and truck runs smooth.
