Extra Duty Gear Oil

Premium Extreme-Pressure Industrial Gear Oil; Formulated with "Clean Gear" Additive Technology

Phillips 66®Extra Duty Gear Oil is a premium quality, heavy-duty, extreme pressure (EP) industrial gear oil developed for the lubrication of heavily loaded enclosed gear drives operating under moderate to severe service conditions. It is specially formulated with “clean gear” additive technology to minimize deposit formation and provide excellent gearbox cleanliness. It is recommended for use in all applications where the equipment manufacturer specifies an AGMA EP gear oil.

Features & Benefits

  • High load-carrying capacity for protection against scuffing and wear
  • Excellent oxidation resistance and thermal stability
  • Excellent deposit control for gearbox cleanliness
  • Protects against rust and corrosion
  • Fast water separation
  • Quick foam release
  • Effective mist suppression (“M” grades)

Applications

• Enclosed industrial gear drives operating under heavy loads, high peak loads or intermittent shock loads

• Enclosed spur, bevel, helical, herringbone and planetary gear drives where the equipment manufacturer specifies an AGMA EP gear oil

• Heavily loaded plain and rolling-element bearings
