Synthetic Heavy-Duty Diesel Engine Oil for Commercial Vehicles

A complete line of lubricants for all industries, made in Houston, Texas, is offered by our brand. We utilize certified API and SAE formulas, combining base stocks from Valero, ExxonMobil, Motiva, and Calumet refineries, with additives from Afton Chemical, Chevron Oronite, Infineum, and Lubrizol. All our products meet and exceed the latest specifications of the American Petroleum Institute (API), Society of Automotive Engineers (SAE), and the American Chemical Council.

Our U1P-Duty SAE 15W-40 Full Synthetic 6 Heavy-Duty Motor Oil, API CK-4/SN, is formulated with synthetic base oils and a premium additive package. This oil is designed for use in high-speed four-stroke cycle diesel engines that meet 2020 model year on-highway and Tier 4 non-road exhaust emission standards, as well as for previous model year diesel engines. This oil is especially effective at sustaining emission control system durability where particulate filters and other advanced after-treatment systems are used.

U1P-Duty SAE 15W-40 Full Synthetic 6 Heavy-Duty Motor Oil, API CK-4/SN, provides enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration, as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase.

In addition to API CK-4, this oil exceeds the performance criteria of CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4, and can effectively lubricate engines calling for those API Service Categories. When using this product in conjunction with fuel containing higher than 15 ppm of sulfur, consult the engine manufacturer for service interval recommendations.

Full synthetic diesel and gasoline motor oil helps reduce wear and increases engine protection. Strong shear stability provides stay-in-grade performance, and the full synthetic formula minimizes oil consumption in all types of driving conditions, offering enhanced oxidation control.

The product's typical properties include: - Appearance: Amber transparent liquid - Viscosity@40°C, cSt, ASTM D445: 105.85 - Viscosity@100°C, cSt, ASTM D445: 15.1 - Viscosity Index, ASTM D2270: 150 - CCS, cP, ASTM D2270: 5,000@-20°C - CCS, cP, ASTM D5293: 15,000@-25°C - Flash Point, °C, ASTM D92: 220 - Pour Point, °C, ASTM D97: -40 - TBN, mg KOH/g, ASTM D2896: 9
