Seiken DIESEL SAE 15W-40 API CI-4 is a heavy-duty diesel engine (HDDE) oil formulated with special technology from Japan, meeting the API CI-4, ACEA E7-16, and DH-1 specifications.

This oil uses high-quality base oil and carefully selected additives, combined with Japan’s Shield Active Technology, to protect the engine from wear, enhance oxidation resistance, and ensure more efficient and optimal performance.

• Stable dual viscosity provides optimal acceleration and engine protection during startup and high-temperature operation.
• Best-in-class superior engine wear protection.
• Excellent control over piston deposits to maintain power and extend oil drain intervals.
• High resistance to oxidation and heat, extending the lifespan of the oil.
• Low evaporation rate, ensuring more efficient and optimal oil consumption.
• Excellent ability to control contaminants and neutralize acids produced during combustion.

Seiken DIESEL SAE 15W-40 API CI-4 is recommended for modern heavy-duty diesel engines (HDDE), especially high-speed engines with Common Rail Direct Injection (CRDi) systems.

It can also be used in diesel-powered vehicles such as distribution trucks, light & medium truck fleets, as well as construction and mining equipment.
