Syncon Mist Oil is a premium quality, synthetic, extreme-pressure (EP) gear oil developed for use in oil mist lubrication systems for enclosed industrial gearboxes operating under extreme-temperature conditions.

Syncon Mist Oil is available in one viscosity grade: ISO 100 (AGMA 3 EP). It is formulated with synthetic polyalphaolefin (PAO) base oils, a misting agent and specially tailored additives that provide extreme-pressure properties and rust and corrosion inhibition. It has outstanding oxidation resistance and thermal stability at high temperatures to help minimize deposit formation, and has high load-carrying capacity for protection against scuffing and wear. The misting agent helps reduce fogging and stray mist.

N/A Syncon Mist Oil is recommended for use in oil mist lubrication systems for:

  • Lightly to moderately loaded enclosed industrial gearboxes with spur, helical, herringbone or bevel gears
  • Chain drives
  • Plain and rolling element bearings in rolling, rod and wire mills
Syncon Mist Oil meets the performance requirements of:
  • AGMA 9005-E02 (formerly 250.04)
  • U.S. Steel 224
Note: Syncon Mist Oil is not recommended for use in worm gear drives with bronze or brass bull gears, since these types of gears require heavier viscosity lubricants with oiliness agents.



  • Outstanding oxidation resistance and thermal stability at high temperatures
  • Excellent low-temperature fluidity
  • High load-carrying capacity
  • Reduces stray mist
  • Low fogging tendency
  • Protects against scuffing and wear
  • Protects against rust and corrosion
