Railroad Diesel Engine Oil 20W40 5th Generation

Heavy Duty Engine Oil
Railroad Diesel Engine Oils 20W40 is a premium grade, heavy duty, crankcase oil, designed for use in railroad diesel engines of American origin, particularly those manufactured by General Electric and General Motors Electro-Motive Division (EMD). It does not contain zinc and therefore can be used in engines fitted with silver piston-pin bearings.

TYPICAL APPLICATIONS

Railroad Diesel Engine Oil 20W40 is designed specially for use in highly rated railroad engines subjected to the most severe operating conditions, especially where fuel sulphur is high (approximately 1%) and where long oil drain intervals are required.

Applications are primarily for railroad locomotives; however, Railroad Diesel Engine Oil 20W40 may also be suitable for certain engines in power.

PERFORMANCE

  • 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 bi- products of combustionPERFORMANCE – Cont’
  • High viscosity index base oils – Provides a higher level of protection than lubricants based on naphthenic mineral oils.
  • Seal & Paint Compatibility – Railroad Diesel Engine Oils 20W40 is compatible with all seal materials and paints normally specified for use with mineral oils.
  • Good anti-wear properties – Maintains a protective film between pistons and their rings and cylinder walls, even under high operating temperatures and pressures.

PERFORMANCE SPECIFICATIONS

  • API Service Classification – CF
  • EMD – Worthy of full scale field Test (WOFT)
  • General Electric – Gen 4 –Long life LMOA -Generation 5
