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.
Performs very well and has raised fuel mileage on an average of 8 miles per gallon.
Havent installed yet. Waiting for the truck to reach at least 5k. Hopefully lives up to description.
Switching from a popular name brand, I noticed lower oil temperatures and a noticeably quieter engine, as well as great clutch performance.
Have high hopes for good results in 2 cycle small engines.
Awesome oil, running it in an air cooled motorcycle with dry clutch.
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.
Excellent product transmission is smooth much better than or fluid
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.
