AMSOIL 15W-40 Diesel Max-Duty Fully Synthetic Engine Oil (DME)

AMSOIL 15W-40 Diesel Max-Duty is a fully synthetic diesel engine oil built for severe on-road and off-road service. It’s engineered to deliver outstanding extreme-pressure protection, help keep turbos cleaner, maintain proper viscosity under soot and heat, and support extended drain intervals in hard-working diesel engines.

Key Benefits

• Outstanding extreme-pressure protection for severe-duty diesel service

• Helps keep turbochargers cleaner and withstand high-heat operation

• Maintains viscosity and resists soot-related thickening for continued protection

• Helps minimize oil consumption

• Excellent performance in extreme hot/cold conditions
