Category:

Shell Caprinus HPD 40

Heavy-duty monograde engine oil for railroad diesel and stationary engines

  • Designed for EMD and General Electric diesel locomotive engines

  • Zinc-free formulation protects silver piston-pin bearings

  • High thermal and oxidation stability for extended oil life

  • Excellent detergency and dispersancy for cleaner engine operation

  • Strong anti-wear film protects pistons and cylinder liners under pressure

  • High viscosity index mineral base oils offer enhanced protection

  • Also suitable for some marine, mine-haul, and power generation engines

  • Approved or recommended by GE, EMD, Detroit Diesel, and LMOA

Global Product Code: 001A0131



Application:

Shell Caprinus HPD 40 is a high-quality, zinc-free, monograde crankcase oil developed specifically for North American railroad diesel engines, particularly those manufactured by General Electric and General Motors Electro-Motive Division (EMD). Its additive system provides alkalinity, dispersancy, oxidation resistance, and compatibility with silver piston-pin bearings, making it ideal for high sulphur fuel conditions and extended oil drain intervals.

Performance Features & Benefits:

  • Zinc-Free Formulation: Safe for use in EMD engines fitted with silver piston-pin bearings, avoiding corrosion or compatibility issues.
  • Superior Engine Cleanliness: High detergency and dispersancy keep engine components free from harmful deposits.
  • Thermal and Oxidation Stability: Maintains performance even under high load and high temperature operating conditions.
  • Anti-Wear Protection: Retains an effective oil film between moving parts under extreme pressures, preventing wear.
  • High Viscosity Index Base Oils: Provides better film strength and stability compared to naphthenic base oils.

Main Application Areas:

  • North American diesel locomotive engines requiring zinc-free oil
  • EMD and GE engines operating under extended service intervals
  • Stationary engines in power generation, marine, and mine-haul sectors

Specifications & Approvals:

  • API CD
  • Detroit Diesel – Recommended for DDC Series 149 under severe conditions
  • EMD – Worthy of full scale field test (WOFT)
  • General Electric – Gen 4 Long Life (tentative approval)
  • LMOA – Generation 5

Usage Instructions:

  • Use according to OEM recommendations for drain intervals and oil performance category.
  • Not suitable for engines requiring multigrade or low-ash formulations.
  • For other applications, consult your Shell technical advisor.

Environmental & Safety Information:

  • Shell Caprinus HPD 40 poses no significant health risk when used as directed and with standard hygiene practices.
  • Avoid skin contact with used oil. Use gloves and wash thoroughly after handling.
  • Do not discharge used oil into drains, soil, or water. Dispose of it at an authorised collection point.
  • Safety Data Sheet (SDS) available via inquiry.
