Product Description

Mobil Delvac Synthetic Transmission Oil V30 is a fully synthetic, heavy duty manual transmission lubricant engineered to meet demanding requirements. Recommended for year-round lubrication of manual transmissions in light to severe duty on- and off-highway equipment operating in a wide range of environments. Designed to provide excellent performance, Mobil Delvac Synthetic Transmission Oil V30 incorporates the latest lubrication technology based on synthetic basestocks and an advanced additive system providing significant advantages over conventional transmission oils. This advanced additive system provides outstanding detergency and dispersancy with optimised protection against thermal degradation, oxidation, wear, and corrosion. Because of its high viscosity index and synthetic base oil mixture, it provides stronger film strength at higher temperatures than conventional oils. This technology also ensures effective lubrication at extremely low temperatures without oil channeling. Mobil Delvac Synthetic Transmission Oil V30 is recommended for manual transmissions and non-hypoid gear-box applications.

Features and Benefits

Today’s technology has vastly improved the performance capabilities of heavy duty trucks in terms of load, speed, control, and reliability through innovative drive train designs. These designs have markedly changed and raised the requirements of drive train fluids to deliver higher levels of performance, while extending drain intervals. For heavy duty transmissions; friction control, wear protection, thermal stability, shear stability, rust, and corrosion protection, as well as seal protection are features that must be optimally balanced, to provide extended transmission and synchroniser life, smooth shift control, improved transmission efficiency, and higher load capability over a wide range of applications and operating environments. The key benefits of Mobil Delvac Synthetic Transmission Oil V30 include:

Features Advantages and Potential Benefits *
Excellent load carrying, anti-wear, and extreme pressure (EP) performance Helps to protect against wear under harsh operating conditions throughout the transmission life
Outstanding protection against deposit formation Contributes to long seal life, extended drain, and service intervals
High protection from corrosion of copper and its alloys Helps to protect and extend the life of synchronisers while delivering smoother shifting performance
Optimised thermal and oxidation protection Contributes to extended drain and service intervals for controlled maintenance costs
Exceptional shear stability Helps to maintain effective viscosity and film strength for better wear protection during severe operation
Outstanding low temperature fluidity Contributes to quicker starts, easy shifting and helps to reduce wear during cold temperature start-ups
Extended drain and service interval capability Helps to reduce operating costs and contributes to improved productivity
Optimised and stable friction properties Contributes to smooth and rapid gear shifting

  * Compared to conventional mineral transmission oils


      Recommended by ExxonMobil for use in:

  • Heavy duty manual transmissions, specifically those requiring Volvo 97307 or Volvo 97318 type oils (refer to owner’s manual recommendation)
  • On-highway commercial light and heavy duty trucking, busses
  • Applications in regions where severe winter temperatures are encountered
  • Applications where extended service intervals and warranties are required
  • Association with Mobil Delvac Synthetic Gear Oils in rear axles for maximum drivetrain efficiency and fuel economy improvement
  • NOT suitable for hypoid gear applications in differentials and final drives, either for topping-off or refills, where API service GL-5 or MIL-PRF-2105E lubricants are specified in the owner manual.
