Cummins CES 20077: An alternative specification offering extended drain intervals. For fleets operating older pre-2010 equipment, CI-4 Plus remains a robust and cost-effective option.
How Cummins Engine Oil Protects Modern On-Highway Engines
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. 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.
Selecting the right lubricant is one of the most critical maintenance decisions for any fleet manager or owner-operator, and the foundation of that decision is the specification of the engine oil. In colder climates, a thinner oil (such as 5W-30 or 10W-30) allows for better circulation during startup, reducing cold-start wear and improving fuel efficiency.
Protecting Modern On-Highway Engines with the Right Cummins Engine Oil
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. The base stock quality determines the longevity of the oil; synthetic bases offer superior molecular uniformity, leading to more consistent protection across extreme temperature ranges.
