Engine Oil
For the 2014 Kenworth W900, engine oil specifications are highly dependent on the specific engine installed. Common engine manufacturers for this model include Cummins and PACCAR. Generally, these heavy-duty diesel engines require oils meeting API CK-4 or FA-4 standards.
- API CK-4: This specification is backward-compatible with previous API categories like CJ-4, CI-4 Plus, and CH-4. It offers improved oxidation stability, shear stability, and aeration control. Most manufacturers recommend SAE 15W-40 for mixed fleet use and varying climates.
- API FA-4: This is a newer category designed for certain 2017 and newer engines for improved fuel economy. It is not backward compatible with older engines and should only be used if explicitly specified by your engine manufacturer. It typically comes in lower viscosity grades like SAE 10W-30.
Capacity: Engine oil capacities for the Kenworth W900 can range significantly, typically between 36 to 44 quarts (9 to 11 gallons), depending on the engine model and oil pan size. Always verify the exact capacity in your engine
