Momenta Railroad Engine Oil is a high-quality lubricant that gives ideal protection against sludge build-up due to its smooth flow, thus it also optimizes the fuel economy. It aids in maintaining the cleanliness of the belt area and other parts of the engine. In addition, it works by minimizing the friction arising from metal-to-metal contact and over generates ideal performance by the engine. It is fit to be used in medium speed two-cycle as well as four-cycle diesel engines. It imparts best oxidation and corrosion resistance properties.



  • Helps maintain a clean ring belt area, valve deck, crankcase and piston undercrowns
  • Has excellent retention for acid neutralization and wear control
  • Sludge build-up due to soot and moisture contamination is minimized
  • Its non-zinc formulation protects silver bearings and helps provoide for minimum wear of rings, pistons, and liners
  • Less than 10 ppm Chlorine

PERFORMANCE LEVELS: Meets and Exceeds:

  • API Service Category CF (BN 17)
  • Electromotive Division of General Motors
  • General Electric Generation 4 Long Life Oils
  • Locomotive Maintenance Officer Assoc. LMOA (Generation 5
