Product Description
U1P-Duty SAE 5W-30 Full Synthetic Heavy-Duty Motor Oil, API CK-4/SN
Engineered for modern heavy-duty diesel engines, U1P-Duty SAE 5W-30 delivers advanced wear protection, exceptional oxidation resistance, and outstanding engine cleanliness under severe operating conditions.
Formulated with premium synthetic base oils and powered by Ultra1Plus™ Advanced Protection Technology, this full synthetic heavy-duty engine oil is designed to provide superior protection against viscosity breakdown, soot-related thickening, oil aeration, and high-temperature deposits while maintaining maximum engine performance and durability.
Designed for use in high-speed four-stroke diesel engines meeting 2017 on-highway emission standards and Tier 4 non-road requirements, this oil is fully compatible with modern emission control systems, including diesel particulate filters (DPF), exhaust gas recirculation (EGR), and selective catalytic reduction (SCR) systems.
U1P-Duty SAE 5W-30 provides enhanced protection against engine wear, piston deposits, catalyst poisoning, particulate filter blocking, and oxidation-related oil degradation—helping extend engine life and maintain long-term performance in demanding heavy-duty applications.
In addition to meeting the latest API CK-4/SN requirements, this oil exceeds the performance standards of API CJ-4, CI-4 PLUS, CI-4, and CH-4, making it suitable for a wide range of heavy-duty diesel engines and mixed fleet operations.
