What Sets TRIAX Apart
API Licensed & Certified License No. 3593
Unmatched Performance
TRIAX engineers high-performance lubricants for applications where failure is not an option. Every formula is built with advanced friction management technology to deliver measurable wear reduction, extended drain intervals, and consistent performance under extreme conditions.
Advanced Friction Management
TRIAX Nano Boron Technology™ uses nano-scale friction modifiers to form a protective tribofilm across high-contact metal surfaces. This microscopic lattice helps reduce the friction coefficient below 0.04, creating a near-frictionless barrier between moving parts.
By bonding to critical wear surfaces, the Nano Boron layer helps reduce metal-to-metal contact, lower operating temperatures, minimize wear, and protect against deposits caused by heat, pressure, and oxidation. The result is smoother operation, stronger film strength, quieter performance, and longer-lasting protection under severe operating conditions.

Improved Viscosity Stability
TRIAX lubricants are engineered to hold their viscosity grade under intense shear, heat, pressure, and extended service intervals. Advanced synthetic base oils and shear-stable additive chemistry help the oil resist thinning, thickening, and viscosity breakdown, so the lubricant maintains the right protective film thickness across cold starts, operating temperature, and high-load conditions.
This helps critical components stay protected with consistent oil pressure, reliable flow, and stable film strength, even in engines, transmissions, compressors, gear assemblies, and hydraulic systems exposed to severe duty cycles. TRIAX also highlights superior viscosity and shear stability across demanding product lines, including heavy-duty and agricultural formulas built for long service life.
Excellent Heat Management
TRIAX heat management starts by reducing the heat created at the source: friction. Its friction management system, including Nano-Boron and Moly technology in many formulas, helps lower metal-to-metal contact and reduce friction-generated heat across critical wear surfaces. TRIAX also notes that its core oil formulations have improved native thermal handling capabilities, helping equipment run at lower operating temperatures across transmissions, engines, compressors, gear assemblies, and hydraulic systems.
By controlling heat more effectively, TRIAX helps slow oxidation, reduce deposit formation, protect against thermal breakdown, and preserve oil integrity under continuous high-stress operation. The result is cooler-running equipment, cleaner components, and more reliable performance under heavy load, high RPM, towing, hauling, or severe operating conditions.
Extended Service Life
TRIAX lubricants are engineered for extended drain intervals and long-mile protection, with select formulas rated for up to 15,000 miles of service life. Built with high oxidation resistance, strong shear stability, and advanced anti-wear chemistry, TRIAX helps oil maintain its protective properties longer under heat, pressure, and severe operating conditions.
By reducing friction, heat, deposits, and viscosity breakdown, TRIAX supports cleaner components, less wear, and fewer service interruptions over time. In demanding engine applications, TRIAX technology helps deliver up to 84% less engine wear and up to 70% fewer turbocharger deposits compared with OEM specifications and API CK-4 qualification requirements.

Real Results. Proven Performance.
My brother and I did awesome transmission service on my ranger get oil it's much cheaper to buy it from them compare if you go to the dealer and get individual quartz and it's the same it probably the same oil so it's good stuff as long as it's ultra low-viscosity for anything that's 10 speed for Ford
TRIAX ULV ATF Full Synthetic
Cheaper than Amsoil
Cheaper and better than Amsoil. 3 motorcycles and 4 vehicles use it.

Triax CVT oil
Replaced OEM Honda CVT oil with this. Its as if there is no transmission at all its so smooth.
TRIAX CVT ATF Full Synthetic
Thank you Triax. My wife has a BMW X1 that requires specific oil. Although I didn’t know this. When taken to local quick lube they refused to service because they didn’t carry the spec oil. Only place I could find it was Triax! I purchased and returned to the quick lube who then serviced the car. I refused to take it the dealer because of previous issues.
TRIAX Euro LV 0W-20 Full Synthetic
Proved Reliability
I have used this oil in our vacuum pumps, the result is impresive, the equipment reached more vacuum, the o-rings are well preserved and the equipment run smooth. It´s great balance price/quality
TRIAX Kompressor MV 100 (SAE 30)
Great Performing Oil
I have used Triax 5/40 and 10/30 in all of my Ford PSD's from 2016 on. The engines run noticeably quieter and smoother. All OA's that I have had performed have come back exceptional and I have absolutely no reservations about using this oil. In fact, I prefer it over any other.
