Heavy Duty Diesel Engine Oil

Bel-Ray® Heavy Duty Diesel Engine Oil is a high-performance SAE 15W-40 API CI-4 licensed motor oil for heavy-duty diesel and gasoline engines. Heavy Duty Diesel Engine Oil SAE 15W-40 is formulated to meet or exceed the performance requirements of many of today’s off-highway engines. The anti-wear capabilities reduce wear, extending the life of rings, liners and main bearings. This formulation also provides superior soot handling and acid neutralization capabilities.

• High TBN allows long oil life and will extend drain intervals, even with higher sulfur diesel fuels
• Advanced detergent and dispersant technology reduces deposit formation
• Improved soot control, even with EGR (Exhaust Gas Recirculation) equipped engines
• Exceptional shear stability, maintaining viscosity over extended use
