SOLAR Premium Series Automatic Manual Gear Oils GL-5 API 140

Description

Solar Manual Gear Oil SAE 140 GL-5 is a premium quality, extreme pressure (EP) gear lubricant formulated using high-viscosity mineral base oils and advanced sulfur-phosphorus additive technology. It meets the requirements of API GL-5 and is specifically designed for hypoid gears and other gear systems operating under high-speed, high-torque, and shock-loading conditions. This oil ensures long-lasting protection, reliable gear performance, and extended service life in severe operating environments.

Available API
140
Applications
  • Suitable for hypoid differentials, axles, and final drives in trucks, buses, construction, and agricultural machinery.
  • Manual transmissions requiring high-performance GL-5 gear oil.
  • Off-highway equipment operating under extreme load and temperature conditions.
  • Not recommended for synchronized transmissions where GL-4 oil is specified.
Features & Benefits
  • Extreme Pressure Protection: Provides outstanding EP performance for hypoid and heavily loaded gears.
  • Thermal & Oxidation Stability: Resists degradation at high temperatures, reducing sludge and varnish formation.
  • Long Component Life: Minimizes gear wear, pitting, and scuffing even under severe shock loads.
  • Rust & Corrosion Inhibition: Offers excellent protection against corrosion and rust during service and storage.
  • Anti-Foam Properties: Reduces foaming to maintain consistent oil film and gear lubrication.
  • Seal Compatibility: Safe for use with common seals and gaskets in gear systems.
Performance Standards
  • Hypoid gear differentials and axle systems where API GL-5 SAE 140 is required.
  • Heavy-duty commercial and industrial vehicles operating in demanding conditions.
  • Equipment exposed to high torque and load conditions such as mining and off-road operations.
