AMSOIL Signature Series Max-Duty 5W-40 Fully Synthetic Diesel Engine Oil (DEO)

AMSOIL Signature Series Max-Duty 5W-40 is a fully synthetic diesel engine oil engineered for severe on-/off-road service. It’s formulated to provide outstanding extreme-pressure protection, maintain proper viscosity (thickness), help minimize oil consumption, keep turbos cleaner, perform in extreme temperatures and support confidently extended drain intervals.
Key Benefits

• Delivers 6X more wear protection
  
• Resists oxidation and the thickening effects of soot contamination
  
• Excels in extreme temperatures for hot operation and cold starts
  
• Helps minimize oil consumption (low volatility)
  
• Helps keep turbos cleaner
  
• Confidently extend drain intervals

Change / Drain Interval (Service Life)

• Heavy-Duty On-/Off-Road: Three times (3X) OEM recommendation, not to exceed 60,000 miles / 600 hours / 1 year, whichever comes first
  
• Turbodiesel Pickup: Two times (2X) OEM recommendation, not to exceed 25,000 miles / 1 year, whichever comes first
  
• Competition Service Life: Provides lasting protection for multiple events; use oil analysis to determine appropriate drain intervals
  
• Gasoline Engine Service Life (where applicable): Two times (2X) OEM recommendation, not to exceed 15,000 miles / 1 year, whichever comes first
  
• Drain intervals may be extended further with oil analysis; refer to the product data bulletin notes for limitations.
  

Note: Always confirm the required viscosity and specifications in your vehicle/equipment owner’s manual before use.
