Product Description & Specifications

Product Description

SAMIC SYN SYNCHRO HD 80W140 GL-5  is a high performance heavy duty gear oil, formulated from high quality Synthetic Blend of base oils and an advanced additive system. These lubricants are designed for automotive heavy-duty transmissions, axles and final drives. Moreover these oils are specially engineered for heavy-duty axles and final drives where extreme pressures and shock loadings are expected.

Features & Benefits

  • Exceptional thermal & oxidation stability protects against deposit formation and oil thickening, thus maintains the life and performance of lubricant and transmission.
  • Outstanding anti-wear properties and excellent film strength provides exceptional equipment protection, that not only results in fewer breakdowns but also helps improve transmission efficiency.
  • Excellent rust and corrosion protection for longer component life.
  • Compatibility with seals and gaskets, leads to minimize oil leakage and reduced contamination.


SAMIC SYN SYNCHRO HD 80W140 GL-5 is suitable for use in all Passenger cars, On-highway light and heavy duty trucks, and commercial vehicles.

  • Suitable for Heavy duty manual transmissions, axles and final drives requiring API GL-5 level performance.
  • Applications like Off-highway industries including: construction, mining, quarrying, and agriculture.
  • Other heavy-duty industrial and automotive applications, involving hypoid gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque exists.
