Railroad diesel engine oil

Shell Caprinus HPD 40 is a premium grade, heavy-duty, crankcase oil, intended mainly for railroad diesel engines of American origin, particularly those manufactured by General Electric and General Motors Electro-Motive Division (EMD).

Although it is fortified by additives providing alkalinity, dispersancy and resistance to oxidation, it does not contain zinc and therefore can be used in EMD engines fitted with silver piston-pin bearings. Shell Caprinus HPD 40, which contains high viscosity index mineral oil, is designed specially for use in highly rated North American railroad engines subjected to the most severe operating conditions, especially where fuel sulphur is high (say around 1%) and where long oil drain intervals are required.

Performance, Features & Benefits

  • Good detergency and dispersancy properties
    A carefully balanced combination of detergency and dispersancy ensures outstanding engine cleanliness.
  • Good oxidation and thermal stability
    Good protection against corrosion by the acidic products of combustion.
  • Good anti-wear properties
    Maintains a protective oil film between pistons and their rings and cylinder walls, even under high operating temperatures and pressures.
  • High viscosity index base oils
    Provides a higher level of protection than lubricants based on naphthenic mineral oils.


Main Applications

  • North American diesel engines subjected to the most arduous duty where 'zinc-free' oils are recommended by the engine manufacturer. Applications are primarily for railroad locomotives, however Caprinus HPD may also be suitable for certain engines in power generation, marine and mine-haul applications.
