TRIAX Fleet Supreme 15W-40 Full Synthetic

The only oil i use on my tractors amd machines

Very good oil. Fast delivery

Everyone has their own preference on oil. I was pennzoil for years in the vehicles after I found out it was closest to cen-pe-co that saved an engine that actually blew the oil filter seal! Seriously, 45yrs old now and only one. Drove it 23miles home and right before I parked it there was lifter tick. Few years ago my brother passed and I took over his car. He built the engine and had oil analysis done. It was recommended to him to run Rotella t6. After other oil analysis' was done it was proven to be best. I then had multiple Polaris's at that time. Thousands of miles and hundreds of hours with t6 everything was clean and ran great. Bought a TYM 474C and up for first service, I dug into certifications and specs. No company had full Synthetic standard certifications for all 3 oils needed. I sent out samples. Bought Triax oil for all three. Full Synthetic in everything. Everything is quieter. Steering, engine, hydo and the hydraulic pump are all smoother and quieter. Engine oil is a dark brown from all the additives and the hydraulic oil is dyed red so it's easy to see in the sight glass. The gear oil pores thin when cold but after being ran and hot when checked drips off the dipstick slow like molasses. Kind of long winded I know but can't say enough good things about their oil and can't wait another 80ish hours for another oil analysis to see what the improvement is over OEM fluids!

I'm looking forward to trying the Triax Fleet Supreme engine oil in my 2024 Duramax. I ordered it directly from trial, but I was disappointed that the 5W40 was out of stock ?, as I live in Mn. where we experience winters with -40° temps at times. The shipping was fast/timely.

Switched from Rotella to Triax a few weeks ago, what a difference. The most noticeable difference is the significantly quieter engine and about 6% better MPG. Going uphill feels a lot less sluggish too.

I have been using this in my utility tractor. After 250 hours it still looks like it is thick and working well. I will be replacing it with the same.

Been using product for about 2 years since it was first recommended by a shop where I get my trucks worked on. Ever since, zero stiction and way better engine operation. No other oil I have used comes close.

I made the switch to full synthetic oil back in the mid-90s after seeing how well it kept gasoline engine temps in check under high RPM conditions. Even with my older vehicles, I only used full synthetic oil, and when I picked out my first pick-up truck after just turning 60, I opted for a diesel since I do all of my own maintenance and have only used full synthetic oil since its first oil change. I have a 24' travel trailer which I tow up to WV from SC once a year on the interstate, so I've recently opted to use TRIAX 15W-40. I'd previously used 5W-40, but reevaluated its benefits in relevant climes and made the switch to 15W-40. I am committed to fulfilling Ford's maintenance requirements for my 2019 F-250's 6.7L PowerStroke, but I also needed to keep in mind that their specifications have to be simplified in order to address owners/operators throughout the range of climates encountered around the world. I therefore settled on 15W-40 since it's properly fitting with the environments and conditions that my truck is subjected to.

I don't submit my oil for technical analysis, since I change it once each year while averaging less than 2,500 miles, but despite the fact that diesel oil is permeated with microscopic carbon-based particles as a result of the high compression involved with these engines, I can attest that it is still slightly transparent when I drain it while the oil is still very warm after having been operated for an extended period of time. My truck's engine exhibits no discernable oil consumption, and I will continue to use TRIAX based on its performance and the fact that it meets Ford's stringent lubrication specifications.

Our old 6.9L Ford IDI loves this stuff. She's a 1986 model, purchased in 1985 as it rolled off the truck. No turbo, and the engine has 375k original miles on it, no rebuilds. She's loud and nasty, but switching to TRIAX a few years ago from a competing brand, she runs a lot smoother.

Excellent quality. Engine sounds great. Going on 18,000 miles on my truck with it. Found my new favorite oil.
