SWEPCO 203 Moly-XP GEAR LUBE is a premium high-performance gear oil formulated with Lubium™II to enhance thermal stability, reduce operating temperatures, improve yellow metal compatibility, and maintain proper viscosity at high temperatures with proven performance (contact us for case studies) in a wide range of mobile and industrial gearbox applications. It also contains Moly-XP for added friction and wear reduction.

Recommended for any gearbox running hot, any gear box operating in a heavily loaded application, any gear box making noise, any gearbox which is leaking at the seals, any gear box which requires frequent make-up oil or has to be shut down at intervals to keep it running.


Key Benefits

SWEPCO 203 Moly-XP GEAR LUBE has many key benefits:

  • Long-drain protection for manual transmissions, industrial gearboxes, gear reducers, gear driven final drives, power take-offs and differential.
  • Excellent yellow metal (Brass, Bronze, and Copper) compatibility. Will not corrode transmission synchronizers or worm gear components.
  • Contains a limited slip additive for differentials and transfer cases.
  • Adhesive/cohesive properties eliminates start-up wear and dry starts, the number #1 cause of gear wear.
  • Unsurpassed rapid and complete water separation for easy removal.
  • Extends oil life two or more times with LOA.
  • Reduces energy consumption in stationary gearboxes.
  • Controls foaming and reduces operating temperatures.
  • Superior varnish, sludge, rust, and corrosion control.
  • Exceeds performance requirements of all major gearbox and OEM specifications.
  • NSF H-2 and Canada Health Compliant for non-food contact.
  • Easy to demonstrate against competitor products.
  • Advanced additive chemistry provides extended drain protection, additional protection from wear, foaming, overheating, sludge, varnish, and carbon deposits. Also prevents rust, corrosion, and water contamination.
  • LOA program makes safe, long-drain service possible.
  • Contains Moly-XP for reduced friction and wear. Ideal for gearboxes that are running hot, over loaded, or over speed.
