Syncon® EP Plus Gear Oil


Phillips 66® Syncon EP Plus Gear Oil is a premium quality, synthetic, extreme-pressure industrial gear lubricant developed for the lubrication of enclosed gear drives and heavily loaded plain or rolling-element bearings operating at extreme temperatures or in severe service. It is suitable for use over a wider temperature range than conventional mineral oil-based gear oils. It meets the performance requirements of major gear drive manufacturers.

Features & Benefits

  • Outstanding low-temperature properties
  • High viscosity index and low pour point for use over wide temperatures
  • Excellent extreme-pressure properties
  • Protection against scuffing and wear
  • Protects against rust, corrosion, and foaming
  • Non-chlorinated additive system
  • Suitable for year-round use
  • Extended service intervals compared to mineral oil-based gear oils


  • Heavily loaded enclosed gear drives, such as those found in mine hoists and mining machinery
  • Enclosed industrial gear drives operating at very low or very high temperatures, or operating continuously at higher than normal operating temperatures
  • Heavily loaded plain and rolling-element bearings operating at extreme temperatures
  • Applications where the equipment manufacturer recommends a high VI, synthetic, extreme-pressure gear oil
