Application

SIMCOE Lubricants Full Synthetic SAE 5W-40 API CK-4 is a premium heavy-duty diesel engine oil, developed to meet the demands of modern turbocharged diesel engines operating under severe duty cycles. Its advanced additive technology delivers outstanding soot control, TBN retention and wear protection, while maintaining engine cleanliness and supporting the durability of DPF and EGR after-treatment systems.

A year-round grade for mixed fleets running modern low-emission diesels: on-highway tractors, vocational trucks, buses and light-duty pickups. Its API SP rating also covers the gasoline vehicles in the same yard, so one drum can serve the whole fleet.

Maximum Engine Protection

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.

Enhanced Fuel Efficiency

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.

Extended Oil Drain Intervals

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.
