What is Gear Oil?

Gear oil is a high-performance lubricant specially designed for gear systems and transmissions. It creates a protective film between moving metal surfaces and prevents direct contact between gears.

Compared to engine oil, gear box oil is thicker and contains special additives that help it handle heavy loads, extreme pressure, and high temperatures.

Industries and vehicles use gear lubricant to:

  • Reduce friction
  • Prevent overheating
  • Improve gearbox efficiency
  • Protect against rust and corrosion
  • Extend machinery life
