It also contains better detergent packages to keep the engine clean and disperses heat more efficiently, which is vital for preventing the formation of harmful deposits. Conventional mineral oils break down too quickly under the high stress of turbocharged diesel combustion.
6.7 Cummins Oil Type Heat Management and Thermal Performance
Unlike gasoline engines, modern diesel powerplants operate under extreme pressures and temperatures, requiring lubricants specifically formulated to handle these brutal conditions. This lower-viscosity synthetic blend is designed to improve fuel efficiency while providing the same robust protection as CK-4, making it ideal for highway driving conditions.
Ford and Ram provide strict guidelines that go beyond the API rating you see on the shelf. 7 Cummins oil type offers superior shear stability, meaning it maintains its viscosity under pressure.
