Triax Fleet Supreme 15W-40 API CK-4 Full Synthetic Diesel Engine Oil (1 Gallon)

The TRIAX Fleet Supreme Diesel Engine Oils are quite possibly the world's best diesel engine oils, providing unparalleled engine protection. These oils deliver tangible performance every minute, every mile, and every time, offering wide-ranging compatibility for peace of mind.

Why choose TRIAX? These oils enable quieter engine operation, lower operating temperatures, a 4-6% improvement in miles per gallon, faster and smoother turbo spooling, and exceptional cold start properties down to -45°F. Outperforming leading brand motor oils by a wide margin, the TRIAX oils are the superior choice.

Featuring a unique friction-modified formula, TRIAX oils are boosted with Nano-Boron and Moly friction modifiers, providing significantly improved wear protection compared to other diesel engine oils. Offering extreme wear protection, these oils can achieve up to 48% lower wear than leading OEM and industry standards, thanks to a much lower friction coefficient (50% lower or better) than the competition.

Ideal for diesel pickup trucks, the TRIAX Fleet Supreme oils are fully compatible with any heavy-duty diesel trucks, including Ford Powerstroke, Chevy Silverado, Dodge RAM, and GMC Sierra, among others. Capable of exceeding 100,000 miles for highway trucks (semi-trucks) and 30,000 miles for Super Duty pickups, these oils deliver the longest drain intervals in the industry.

Boasting improved durability, the TRIAX oils maintain their viscosity better than other diesel oils, protecting your engine in severe service conditions such as towing or hauling, without compromising drain intervals. Moreover, these oils eliminate HEUI injector stiction, preventing injector lockup, engine misfires, and a host of other issues, eliminating the need for additional aftermarket additives. Everything you need is built into the TRIAX formulation, optimized for unmatched performance.

Lastly, the TRIAX Fleet Supreme Diesel Engine Oils are designed to keep your diesel particulate filters clean, prevent clogging, and maintain optimal engine functionality. Fully compatible with all heavy-duty CK-4 or previous diesel engines, including Volvo, Cummins, Detroit Diesel, MAN, Scania, Powerstroke, and Duramax, these oils provide unparalleled protection and performance for your diesel engine.
