Gulf Syngear TDL 75W-140

Fully Synthetic Total Driveline Lubricant

Gulf Syngear TDL 75W-140 is thermally stable fully synthetic total driveline gear lubricant designed to meet the severe requirements of drivelines of light and heavy duty commercial vehicles. It is blended from fully synthetic base stocks and advanced performance additives to provide improved fuel economy, excellent protection to driveline components, improved gear shifting. It provides reliable protection against thermal and oxidation degradation, rust & corrosion and has excellent low temperature fluidity. It is approved against Scania STO 1:0 for both Gearbox and Axel Gears and also meets the requirements of API GL-5/MT-1, MIL-PRF-2105E, SAE J 2360 and MAN M 342 Type M2.

Features & Benefits

  • Excellent load-carrying capability to protect gear components against wear in different operating conditions enhances equipment durability and reduces maintenance costs.
  • Blended with fully synthetic base stock and advanced additive technology provides improved fuel economy benefits.
  • It provides outstanding thermo-oxidative stability that helps in extending the life of the driveline components and the oil.
  • The advanced additive technology allows the use of a single lubricant in rear axle and manual transmissions and therefore helps in rationalisation of products.
  • Effective rust and corrosion protection, especially to copper and its alloys, reduces wear and extends life of gear components.
  • Exceptional low temperature fluidity reduces wear and provides easy gear shifting.
  • Good anti-foam properties ensure film strength for effective lubrication.
  • Superior seal compatibility minimises leakage and reduces chance of contamination


  • Gearboxes and Axle gears of Scania Trucks, Buses & coaches requiring oils approved against Scania STO 1:0
