Manufacturer's description

Railroad Diesel Engine Oil. Shell Caprinus XR oils are 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). Shell Caprinus XR oils use the latest, low-chlorine additive technology which offers both environmental benefits and improved performance. Shell Caprinus XR oils do 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. The performance of Shell Caprinus XR has been demonstrated in highly rated North American railroad operation subject to the most severe operating conditions.

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 XR 40 may also be suitable for certain engines in power generation, marine and mine-haul applications.
• Shell Caprinus XR Oils are low chlorine formulations meeting the requirements of leading railroad operators in North America.

Performance & benefits

• Excellent detergency and dispersancy propertiesA carefully balanced combination of detergency and dispersancy ensures outstanding engine cleanliness.
• Good oxidation and thermal stabilityGood protection against corrosion by the acidic products of combustion.
• Good anti-wear propertiesMaintains a protective oil film between pistons and their rings and cylinder walls, even under high operating temperatures and pressures. Use of low-chlorine antiwear additives ensures protection of valve trains and other parts.
• High viscosity index base oilsProvides a higher level of protection than lubricants based on naphthenic mineral oils.
• EMD - Approved “Worthy of full scale field test” (WOFT)
• Detroit Diesel - Recommended for DDC Series 149 engines under severe conditions
