# LBPH778906

Synthetic Automotive Gear Lubricant

Phillips 66® Triton Synthetic Gear Lube is a synthetic, multipurpose, extreme-pressure, API GL-5 automotive gear lubricant. It is specifically designed for use in passenger car and truck axles with hypoid gear sets operating in extreme temperatures or under severe driving conditions.

Features & Benefits

  • Extended drain, all-season performance
  • Outstanding oxidation resistance and thermal stability to minimize sludge and varnish formation
  • Excellent thermal durability and extreme-pressure properties for extended gear life
  • High load-carrying capacity for protection against scuffing and wear
  • High shear stability
  • Outstanding low-temperature properties
  • Protects against rust and corrosion
  • Good foam resistance
  • Potential fuel savings compared with conventional SAE 85W-140 gear oils


  • Service fill of conventional differentials in passenger cars and trucks
  • Top-off only of limited-slip differentials in passenger cars and light trucks
  • Service fill of differentials, final drives and transfer cases in some off-highway equipment
  • Non-synchronized manual transmissions in trucks, buses and heavy equipment where the manufacturer specifies an API GL-5 or MT-1 gear oil
