APEX 15w40 Syn is a synthetic blend heavy-duty diesel engine oil that meets the CJ-4 specification, provides the highest level of protection in severe on- and off-highway to modern, high performance diesel engines with Exhaust Gas Recirculation (EGR), Aftertreatment Systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs).

It exhibits outstanding low temperature fluidity, high temperature viscosity retention, and piston deposit control.

Benefits:

• Oxidation performance superior to most conventional oils.
• Excellent anti-wear and anti-scuff properties.
• Extended drains beyond conventional oils.
• Excellent low-temperature performance allows oil flow to critical bearing surfaces at start-up and controls low-temperature sludge formation in stop-and-go service.
• Stay-in-grade shear stability protects engine parts at high operating temperatures and reduces oil consumption.

APEX 5w-40 Syn meets or exceeds the requirements of:

• API CJ-4/CI-4 PLUS/CI-4/CH-4/SM/SL.
