Caprinus XR oils are a premium grade, heavy-duty, engine oils, intended mainly for railroad diesel engines of North American origin, particularly those manufactured by General Electric and General Motors Electro-Motive Division (EMD). It does not contain zinc and are approved for use by GM-EMD for their engines fitted with silver piston-pin bearings and by GE for their latest locomotives.
Suitable for 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 XR may also be suitable for certain engines in power generation, marine and mine-haul applications.
Caprinus XR oils are low chlorine formulations meeting the requirements of leading railroad operators in North America
