Description
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. 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.
