Fast Cold-Start Flow

Reliable cold-flow properties support startup protection and quicker lubrication delivery in cooler conditions.

Thermal Stability

Resists viscosity breakdown and oxidation under high operating temperatures for consistent heavy-duty engine protection.

Outstanding Wear Control

Helps protect liners, bearings, cams, and valve-train components from wear under high-load and long-haul operation.

Deposit & Sludge Control

Strong detergent package helps minimize piston deposits and ring sticking to support performance and service life.

High-Load Durability

SAE HD-50 viscosity provides strong oil-film strength for sustained protection in heavy-duty and high-temperature service.
