Global Product Code: 001A0897



Application:

Shell Caprinus XR 40 is a premium monograde engine oil developed for high-performance railroad diesel engines manufactured by General Electric (GE) and Electro-Motive Division (EMD) of General Motors. It uses low-chlorine, zinc-free additive technology to deliver enhanced protection, extended drain intervals, and compatibility with silver piston-pin bearings—making it ideal for use under the most severe railroad operating conditions in North America.

Performance Features & Benefits:

  • Outstanding Engine Cleanliness: Balanced detergency and dispersancy provide excellent deposit control and keep engines clean.
  • Zinc-Free Additive System: Safe for use in engines with silver piston-pin bearings—essential for EMD compatibility.
  • Excellent Oxidation & Thermal Stability: Protects against sludge formation and viscosity breakdown at high operating temperatures.
  • Superior Anti-Wear Protection: Maintains oil film integrity under high loads and pressures, protecting valve trains and liners.
  • High Viscosity Index Base Oils: Offers better protection and performance compared to naphthenic base oils.
  • Environmentally Friendly: Low chlorine formulation helps reduce environmental impact during disposal.

Main Application Areas:

  • North American railroad diesel engines (GE and EMD)
  • Engines in power generation, marine, and mine-haul operations where zinc-free oil is required
  • Applications requiring long drain intervals and reliable performance in harsh operating environments

Specifications & Approvals:

  • API CF
  • EMD – Approved “Worthy of full scale field test” (WOFT)
  • General Electric – Gen 4 Long Life
  • Detroit Diesel – Recommended for DDC Series 149
  • LMOA – Generation 5

Usage Instructions:

  • Use according to OEM-recommended drain intervals and compatibility guidelines.
  • Not intended for engines requiring multigrade or low-ash oils.
  • For other applications, consult your local Shell representative.

Environmental & Safety Information:

  • Shell Caprinus XR 40 is unlikely to present a significant health or safety hazard when used correctly.
  • Use gloves when handling used oil. Wash skin after contact with soap and water.
  • Do not dispose into drains, soil, or water. Use authorised collection points.
  • Safety Data Sheet (SDS) available via inquiry.
