Conventional 15W-40 CI-4 Heavy Duty Motor Oil

Our Conventional 15W-40 CI-4 Heavy Duty Motor Oil is specifically formulated to meet the demanding requirements of modern diesel engines operating under high loads and extreme conditions. Blended with high-quality base oils and advanced additives, it delivers exceptional wear protection, oxidation resistance, and deposit control.

The 15W-40 multi-grade viscosity provides excellent cold-start performance while maintaining strong oil film protection at high operating temperatures. This balance makes it ideal for heavy-duty on-highway trucks, off-road equipment, and other severe-service applications.

Certified to API CI-4 standards, this oil is designed for engines equipped with Exhaust Gas Recirculation (EGR) systems and is compatible with engines meeting 2004 emission standards and earlier. It offers outstanding soot control to minimize abrasive wear and maintain cleaner engine operation, even with high soot loading.

Key Benefits:

• Superior wear protection under heavy loads and severe service

• Excellent soot dispersion to reduce abrasive engine wear

• Enhanced thermal stability and oxidation control for long oil life

• Advanced detergency to keep engines clean and reduce sludge

• Compatible with turbocharged and naturally aspirated diesel engines

The trusted choice for fleets, construction, agriculture, and industrial applications requiring 15W-40 CI-4 rated heavy-duty motor oil.
