Ultra1Plus SAE 15W-40 Full Synthetic Heavy-Duty Diesel Engine Oil - API CK-4/SN Certified Motor Oil (5 Gallon Pail) for Trucks, Construction Equipment & Fleet Vehicles - Ideal for Extreme Temperature Performance

Product Description

SAE 15W-40 Full Synthetic 6 Heavy-Duty Motor Oil API CK-4/SN SAE 15W-40 Full Synthetic Heavy-Duty Motor Oil, API CK-4/SN 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 for use in high-speed four-stroke cycle diesel engines designed to 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 Full synthetic motor oil minimizes oil consumption in all types of driving conditions. Enhanced oxidation control.
