"Got Triax Fleet Supreme 5W-40 from a local diesel shop, said it stops injector issues with the Powerstroke engines without the need for additional additives. They were right. Never used another oil since 2018, have had no more injector issues of any kind since then. "
Angelo | Minnesota (TRIAX FLEET SUPREME 15W-40 CK-4 Full Synthetic)
"Without any doubt the best diesel oils I have used in my 30 years driving my trucks. Quiet engines, no injector issues, turbo spools instantly and after a night out at - 20 my truck starts without hesitation and to top it all off, got an extra 2 mpg on my fuel."

We own a diesel shop in Austin TX and bought Triax Fleet 5W-40 once off Amazon to give a few customers as we had run out of our usual product. We never had so many customers come back and ask for a specific product so many times. Every driver that we gave it to originally, wanted Triax again and we have been carrying their products since. Excellent products.

Probably the best ATF we have used in our cars. All of them have over 200k miles and since we changed no Triax Global ATF transmissions shift smoother, no more slipping and hard shifts. On my truck the transmission is 19 F cooler and I work it pretty hard.
Earl S. | Las Vegas (TRIAX GLOBAL Full Synthetic ATF)
We average 120,000 miles oil changes on our Peterbilt highway fleet, which is absolutely outstanding. This is not just one time, its oil change after oil change. We run 94 trucks. I have been doing this 20 years and have not been able to get this out of any oil. 60k miles was the most we could get from a Rotella or Valvoline. Customers for life.

When your logging equipment hydraulics function at -20 F without any worries and you can go do your thing without warming it up so the oil will flow, equipment responds instantly to commands, smooth, no jerking - what else do you need? I stopped changing fluids 4 times a year, now we do it only once. Huge headache off my back not to mention money.
Sandy | Logging | Colorado (TRIAX AGRA UTTO Supreme Tractor Hydraulic Oil)
I have owned a logging business for 15 years and used a lot of oils. Triax has been the best product we have used by far. We get -30F here in the winter and their hydraulic oils work like normal, engines start without a hitch. During the summer, we work around the clock and have no heat issues, my 20 ton lifters dont take a break, dont overheat and dont lose power. Everything ive used from Triax has been top of the line, through and through. We are customers for life.

Top notch power steering fluids, I use it in all 5 cars. No winter or summer issues. Cheaper and better replacements for stupid expensive OEM fluids.
Ernesto | California (TRIAX POWERFLUID 450 CHF 11 S - Power Steering | Hydraulic)
We use TRIAX fluids in all of our shop, all 12 of them, especially their SRT and Euro engine oils. Customers love them, quality is great and top notch service from Devon our rep.
Daniel | Texas (TRIAX SYNERGY SRT 10W-40 Full Synthetic High Mileage)
Great oils for BMWs. I used it in all 4 of mine for the past 3 years and the engines are very happy. Oil analysis is also good, I regularly sent them out to Blackstone. I made the switch 3 years back when my wife's X5 OEM oil 0W-20 from BMW came back critical across the board after 3k miles. Triax now runs 12k miles and is still good.
Daniel | Texas (TRIAX EURO LX 5W-40 Full Synthetic)
Absolutely great hydraulic oils, been using the Powerflow 46 for 8 few months in 44 Cat units and they work better than with the Cat Hydo 10. Better response and longevity that the OEM CAT fluids, higher zinc too. Great stuff.
Mandy | Ohio (TRIAX POWERFLOW HLP ISO 46)
No more transmission noise and more power on both my tractors. One of the first things I noticed is that the pinions dont whine when I start rolling for 15 minutes like before. Good oils, will keep using them.
Michael | New Mexico (TRIAX AGRA UTTO XL Tractor Hydraulic)
I never thought I would switch the entire farming fleet to one single brand. We got Kubotas, Case, JDs and Deutz equipment here and if you listen to what all them tell you, you get for each their own oem fluid. Never really found a fluid that can cover all the specs and perform. The Kubota fluid makes the JD transmissions whine, the JD engine oil is being burned up by the air cooled Deutz engines likes its drinking it. Finally with TRIAX we have a brand that works on everything without issues. Outstanding quality.
