Super Three Star® Synthetic Gear Lubricant

Full Synthetic Extended-Drain Automotive Gear Lubricant


Kendall® Super Three Star Synthetic Gear Lubricant is a full synthetic, API GL-5 automotive gear lubricant specially designed for long-drain service and extended warranty protection in passenger car and truck axles with hypoid gear sets.

Features & Benefits

  • Extended drain/extended warranty protection
  • 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
  • Excellent water-separating properties
  • Protects against rust and corrosion
  • Good foam resistance
  • Compatible with synthetic and conventional automotive gear oils

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.
