TRIAX Synergy SRT 5W-30 Full Synthetic
Wade Prunty
Great Full Synthetic Oil for Dexos1 HD Gasser

I'm using this in my 2026 GMC Sierra HD 2500. I also run the Pro Engine Flush during each oil change. I pull the max weight with this truck with a gooseneck and utility tractor, and it does a great job, even on long trips. Because of that I wanted to make sure I was using the best oil I possibly can, though within my means. For this I landed on their Synergy SRT Full Synthetic Engine Oil. There are two other brands that people hold up as the best you can get, and I am one of them, but after using TRIAX across my ag lineup, and all farm vehicles, I've come to believe TRIAX is absolutely at that same high level, and even surpasses them in a lot of areas. One of the bonuses though is that TRIAX continuously runs big sales on their website, and that really makes their products affordable. Another bonus is I'm in East Texas. If I place my order on their website in the morning I usually have it delivered the next afternoon. And with free shipping on orders over $50, you can't beat that at all.

Switching from a popular name brand, I noticed lower oil temperatures and a noticeably quieter engine, as well as great clutch performance.

Awesome oil, running it in an air cooled motorcycle with dry clutch.

R
TRIAX Trans-Zero 20W-50 Full Synthetic
Ryan Bridges (United States)
Great product and great value

The trans zero is a great value as we irsrrtthe 4 flock to run in our zero turn mowers. Our mowers run quieter with the trans zero in the hydro motors and help performance during the long hot summer days of continuous operation. Definitely a recommended product.

Replacing Amsoil in honda. We will get analysis of oil after 5k. See what the results tell us.

TRIAX Agra UTTO Supreme Tractor Fluid - Full Synthetic - (GL-4)
Chris (United States)
Great product

We're able to use this in our farm equipment which consists of several different brands. Transmission/hydro runs cooler. Increased run times over previous fluid. The only reason I didn't give 5 stars is the new 5 gallon "jug" doesn't hold up as well as the bucket (which I can always re-purpose). Attached is a picture of how I received it.

TRIAX Fleet Supreme 5W-40 Full Synthetic
Craig A McCormick (United States)
Satisfied first time user

Ordering and payment went smoothly. Shipped and arrived within days. The 5 gallon jug is well designed and so simple to use, not bulky at all. This is my first time using, I've run Rotella T6 15/40 for years in my 2000 F350 7.3 and wanted to change to 5/40 for the cold winters we get. A friend suggested Triax and after reading all the test results and reviews the choice was simple. Triax stands out as a superior oil in comparison. You can't beat the additive package which means I don't have to supplement with one. I really like the loyalty program and how passionate they are about their products and you simply cannot best the price point, especially when they run a sale. I'm switching all my vehicles over to Triax lubricants.
So how did it do in the 7.3 HUEI diesel? Better starts, less noise, injectors seem to love it. I'm going to run for 5000 miles and pull a test sample. If I can go another 5000 I'll be over the happy and convinced Triax is the best oil on the market.
Thank you Triax for doing everything so well and making a superior product. I'm sure I'll be a longtime customer.

TRIAX Kompressor MV 100 (SAE 30)

Compressor oil that takes the pressure

To be honest this oil I found on the webpage.
It reminded me to change the compressor oil.
This is the good stuff!

TRIAX Synergy SRT 5W-20
Kelly Hammack (United States)
5w-20 synthetic motor oil

Whether it's engine oil, gear oil or transmission fluid, i now use Triax products in everything. Being an old school mechanic, it took me a while to get on board with synthetic lubricants, but it is all I use now, and my lubricant of choice is Triax. It is seemingly an excellent product that I'm now using in all the equipment on my small cattle ranch, to include my hot rod. Give it a try, and soon you'll love it as much as I do.

TRIAX Agra UTTO XL

Great hydraulic oil

I started using this hydraulic oil in my Bobcat CT2025H and then my Kioti NS6010H. I can really tell the difference. The hydraulics are very responsive. Price is good too! Thanks.

TRIAX Synergy SRT 5W-30 Full Synthetic

I don't trust the super thin oilsI

Many of the car manufacturers recommend 0W-20 oils. I suspect this is due to pressure from the EPA and CAFE standards that are putting miles per gallon numbers ahead of engine longevity considerations. So I am selecting Triax 5W-30 oil for my wife's car which, I believe, will be superior in avoiding unnecessary and early engine wear due to excessively thin oil. I think the EPA has gone way too far with excessively stringent emissions and mileage standards and the car owners are and will be paying for it with premature engine wear.

High quality

Very, very smooth running engine after a triax oil change

P
TRIAX Agra UTTO Supreme Tractor Fluid - Full Synthetic - (GL-4)
Patrick Macan (United States)
Less Hyd Whine

This oil has quieted down the whine I got with lesser oils. I am more confident that my equipment is properly protected and will last years.
