AMSOIL Industrial EP Series-MPT Micropitting-Tech Extreme-Pressure Gear Oil is engineered with advanced EP and micropitting technology and superior thermal stability to provide complete gear and bearing protection in gearboxes operating under severe-service, extreme-pressure and shock-loading conditions.

  • Superior film strength for advanced micropitting protection.
  • Excellent extreme-pressure wear protection.
  • Outstanding protection against shock loading.
  • Quick air release to maintain a thick lubricating film.
  • High thermal stability to prevent sludge and deposits.
  • Inhibits corrosion to maximize gear and bearing life.
