SYNGEAR 75W/90 V EXTRA represents a synthetic oil-based gear lubricant meticulously crafted to adhere to the demanding Volvo 97312 specification, boasting an impressive long-drain performance. This specialized lubricant finds its niche in synchromesh transmissions and commercial vehicle axles, particularly excelling in scenarios necessitating heightened load-bearing capacity and exceptional thermal stability. Furthermore, it is highly recommended for use in various essential gear components, including differentials, final drives, manual transmissions, transfer cases, and more.

One notable distinction of SYNGEAR 75W/90 V EXTRA is its official OEM approval from Volvo, meeting the exacting standards of Volvo Transmission Oil 97312-012.

This superior lubricant delivers a comprehensive set of benefits, including outstanding performance in high-temperature and high-load conditions, impressive low-temperature fluidity and cold flow characteristics, excellent corrosion protection, and superior compatibility with seals. Even in the face of rigorous mechanical shearing encountered in demanding applications such as hypoid gear setups and other severe automotive gear scenarios, SYNGEAR 75W/90 V EXTRA maintains its exceptional viscosity/temperature properties. Its robust qualities make it a dependable choice to ensure the efficiency, longevity, and reliability of critical gear systems in both commercial vehicles and various gear applications.


  • ANTI-WEAR CAPABILITIES. Protects components against wear under normal loads.
  • EXTREME PRESSURE CAPABILITIES. Protects components from failure under shock and high loads.
  • SPALLING PROTECTION. Provides axle gear sets with metal fatigue protection.
  • THERMAL DURABILITY. Prevents gear spalling at high temperatures and loads.
  • SHEAR STABILITY. Shear-stable viscosity modifiers used to ensure this wide span multigrade oil ‘stay in grade’.
  • PREVENTION OF OIL LEAKAGE. Oil seal compatibility helps to keep the oil in the axle and maintain lubrication.
  • OXIDATION AND THERMAL STABILITY. Prevents oil thickening and deposit formation, resulting in better component protection.
  • ANTI-FOAM CHARACTERISTICS. Prevents breakdown of and maintains the protective oil film, enabling constant lubrication of components.
  • RUST AND CORROSION PREVENTION. Protects system parts from water.

SYNGEAR 75W/90 V EXTRA is recommended for the lubrication of manual synchromesh transmissions, axles, differentials, final drives, transfer cases and other gear applications where long drain performance is required, such as in Volvo, DAF, Iveco, Mack, Mercedes Benz, Scania, Renault and MAN vehicles and those using Arvin Meritor and ZF equipment.
