TRIAX Fleet Supreme 15W-40 Full Synthetic

good oil for older diesels and tractors

Got my order in earlier today of 15w-40 with the new 5 gallon container. THANK YOU Triax. Worlds better than the old 5 gallon buckets. No need to transfer oil to a smaller to help with refilling the engine.
Kudos on this new design.

Wonderful oil for all the 6.0 owners. Have been running this oil in my truck for the last 5 years and will never run anything else as long as it’s available. Just bit the bullet and had the engine completely resealed and new gaskets at 190,000 miles and the engine bearings looked to have minimal wear and very little sludge or coking inside the engine.
Better cold starts, less injector noise and better fuel economy through an oil change cycle. I also use the synergy gear oils in my truck. Thanks for supplying a great product.

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.
