Performance like nothing else TM
The TRIAX Fleet Supreme product line is a our flagship heavy duty diesel oil and one of the most sought after diesel oils. Its a full synthetic, friction modified engine oil designed for heavy duty turbo diesel engines requiring an API CK-4 specification, with full backwards compatibility to CJ-4 and CI-4. It also exceeds a wide range of OEM specifications such as VOLVO VDS-4.5, Cummins, Detroit Diesel, Mack, Ford, Chevy and many others in all types applications (heavy duty highway, pick-up and haulers). 

TRIAX Fleet Supreme oils are known for eliminating injector stiction in HEUI oil pressure injectors, quiet engine operation, significantly improved fuel economy and extreme drain intervals.

This product uses a unique combination of nano boron and organic moly friction modifiers for outstanding high temp protection, fuel economy and wear prevention. This is coupled with a state-of-the-art boronated dispersant system that actually helps prevent the formation of carbon deposits (prevents it clumping and sticking to parts) to keep your engine extremely clean. 

TRIAX Fleet Supreme Diesel Oils come in 5W-40, 5W-30, 10W-30 and 15W-40 viscosity grades.

Goodbye Rotella
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.


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


Michael
Great product
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.

Question:
can I use this in my gas 3.3l toyota engine?
posted by S.B. at 2022-09-22 23:00:33
Answer:
If the recommended viscosity grade is 15W-40, yes, but for a Toyota you would most likely need a 5W-30 or 5W-20 engine oil
