Currently, the CJ-4 and CK-4 ratings represent the highest levels of protection for modern on-highway engines, offering enhanced protection against phosphorous sulfate ash, which can clog diesel particulate filters (DPF). The correct oil acts as the lifeblood of the powerplant, managing heat, neutralizing contaminants, and minimizing friction across thousands of precise moving parts.
Cummins Engine Oil CES 20077 Specifications: Understanding the Latest Performance Standards
API FA-4: Designed for lower viscosity and improved fuel economy in specific applications. Viscosity and Temperature Management Viscosity is the measure of an oil's resistance to flow, and choosing the right grade is essential for optimal engine performance.
Modern formulations are designed to handle the thermal stresses of aftercooled exhaust gas recirculation (EGR) and the high torque output of the latest generations. The advent of synthetic technology has blurred these lines, with multi-grade oils like 5W-40 providing the cold-flow benefits of a winter grade while maintaining the high-temperature stability of a summer grade.
Cummins Engine Oil CES 20077 Specifications and Performance Details
The Science Behind Cummins Engine Oil Cummins engines are engineered to operate at higher pressures and temperatures than many competitors, which places unique demands on the oil circulating through the system. These original equipment manufacturer (OEM) certifications ensure that the oil has passed rigorous dynamometer testing specific to Cummins hardware.
