Application:

Shell Rotella DD+ 40 is a heavy-duty monograde diesel engine oil formulated specifically for all two-stroke diesel engines manufactured by Detroit Diesel Corporation. This oil meets Detroit Diesel’s rigorous standards for valve seat deposit control and delivers exceptional thermal stability and engine cleanliness in severe operating conditions. It is also suitable for use in certain four-cycle diesel engines in off-highway applications.

Performance Features & Benefits:

  • Low Ash Technology: Helps prevent valve distress and reduces the formation of combustion chamber deposits, ensuring long engine life and emissions compliance.
  • Oxidative Stability: Resists thermal breakdown under high-temperature conditions to maintain oil performance and cleanliness.
  • Superior Wear and Corrosion Protection: Guards engine components against scuffing and accelerated wear.
  • Detergent System: Maintains long-term engine cleanliness and stabilizes Total Base Number (TBN) for consistent performance.
  • Monograde Shear Stability: SAE 40 formulation ensures reliable lubrication and viscosity control in all critical areas of the engine.

Main Application Areas:

  • Detroit Diesel two-stroke engines (including Series 149 used in mine haul trucks)
  • Selected four-stroke diesel engines in off-highway applications (where permitted by OEM)

Usage Instructions:

  • Use only in applications requiring API CF-II or CF specification and low-ash monograde diesel oils.
  • Consult OEM or Shell Technical Helpdesk for guidance on use in 4-cycle diesel engines.
  • Ensure oil change intervals align with engine manufacturer requirements for severe-duty cycles.

Environmental & Safety Information:

  • Use protective gloves when handling used oil. Avoid prolonged skin contact and wash thoroughly after use.
  • Used oil should be returned to an authorized collection point. Do not dispose into drains, soil, or water sources.
