Application
SIMCOE Lubricants SAE 15W-40 API CK-4 is a heavy-duty diesel engine oil in the grade North American diesel service specifies more than any other. It holds its TBN and controls soot over a long drain, in on-highway trucks as much as in construction and farm equipment, and it is compatible with DPF and EGR after-treatment.
The default fill for mixed and older fleets, construction and agricultural equipment, and any engine whose manual calls for SAE 15W-40 under API CK-4, CJ-4 or an earlier category.
A heavy-duty additive system keeps a durable anti-wear film on liners, cams and bearings through the sustained load and long duty cycles of a turbocharged diesel.
Shear-stable viscosity and low-friction chemistry cut parasitic drag through the valvetrain and bearings, which shows up as fuel saved across a fleet's mileage.
Soot handling, oxidation stability and TBN retention keep the oil in grade between services, so the engine can run the drain interval its manufacturer publishes.
