Ultra1Plus SAE 5W-40 Synthetic Diesel Engine Oil

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

The product description is for the SAE 5W-40 Full Synthetic Heavy-Duty Motor Oil, API CK-4/SN Ultra1Plus. This oil is formulated with synthetic base oil and a premium additive package, designed for use in high-speed four-stroke cycle diesel engines that meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards, as well as for previous model year diesel engines.

The oil is especially effective at sustaining emission control system durability where particulate filters and other advanced after-treatment systems are used. It 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, the engine manufacturer's service interval recommendations should be consulted.

The oil exceeds performance requirements of API CK-4, CJ-4, CI-4 Plus, CI-4, CH-4, SN, SM, SJ, and SF, as well as Daimler MB 228.31, Deutz DQC III-10 LA, ACEA E9-12, Ford WSS-M2C171-F1, Volvo VDS-4.5, Cummins CES 20086, Renault Trucks RLD-4, Mack EOS 4.5, MTU Type 2.1, DDC 93K222, and Caterpillar ECF-3.

The oil provides extended service interval, improved wear protection, and resistance to viscosity loss. Its typical properties include SAE 5W-40 viscosity grade, amber transparent liquid appearance, 86.8 cSt viscosity at 40°C, 14.5 cSt viscosity at 100°C, 5,600 cP CCS at -30°C, 22,000 cP MRV at -35°C, 218°C flash point, and -40°C pour point.

The key benefits of the U1P 5W-40 Full Synthetic Oil are that it fights wear, reduces oil consumption, and offers improved fuel economy for heavy-duty diesel engines. It also safeguards Diesel Particulate Filters (DPF) and other after-treatment systems, promoting cleaner emissions. The full synthetic base oil resists heat breakdown, providing continuous protection and optimal oil pressure throughout extended service intervals. The oil is approved for 2017+ on-highway and Tier 4 off-road diesel engines, while remaining compatible with older models, and offers superior wear protection compared to previous API CJ-4 oils.
