AMSOIL Commercial Grade Diesel Engine Oil

AMSOIL Commercial Grade Diesel Engine Oil provides a cost-effective synthetic-blend lubricant option for diesel engines operating in commercial, fleet and equipment applications. It is designed to deliver dependable wear protection, engine cleanliness and lubricant performance where reliable day-to-day service is the priority.

Synthetic-Blend Protection for Working Equipment

Commercial diesel engines can spend long periods operating under load, idling, towing or working in conditions that place significant thermal and mechanical stress on the lubricant. Commercial Grade Diesel Engine Oil combines conventional and synthetic base-oil technology to provide dependable protection for appropriate diesel applications while offering a practical choice for fleets and equipment with regular service schedules.

The correct diesel lubricant should always be selected according to the engine's required viscosity and performance specification. Product tier alone does not determine suitability, particularly where modern emissions systems or manufacturer-specific requirements are involved.

Check the engine or equipment manufacturer's lubricant recommendations before selecting a viscosity grade.
