MP Gear Lube

Multipurpose Automotive Gear Lubricant, API GL-5/MT-1

Phillips 66®Gear Lube is a multipurpose, API GL-5 automotive gear lubricant specifically designed for use in passenger car and truck axles with hypoid gear sets. It also is recommended for use in some heavy-duty manual transmissions in trucks and buses.

Features & Benefits

  • Excellent oxidation resistance and thermal stability to minimize sludge and varnish formation
  • Excellent thermal durability and extreme-pressure (EP) properties for extended gear life
  • High load-carrying capacity for protection against scuffing and wear
  • Protects against rust and corrosion
  • Good foam resistance

Applications

  • Service fill of conventional differentials in passenger cars and trucks
  • Top-off only of limited-slip differentials in passenger cars and light trucks (1)
  • 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

(1) Note: For complete drain and refill, many limited-slip differentials may require the manufacturer's specified gear lubricant or supplemental additive. Refer to the owner's manual for specific requirements.
