Mobil Delvac 1™ Transmission Fluid V30

Supreme performance transmission lubricant

Mobil Delvac 1 Transmission Fluid V30 is a full synthetic, heavy-duty manual transmission lubricant engineered to meet demanding requirements.

Recommended by ExxonMobil 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 1 Transmission Fluid V30 incorporates the latest lubrication technology based on synthetic base stocks and an advanced additive system providing significant advantages over conventional transmission oils. This advanced additive system provides outstanding detergency and dispersancy with optimized 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 1 Transmission Fluid V30 is recommended for manual transmissions and non-hypoid gearbox applications.

Mobil Delvac 1 Transmission Fluid V30 is 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, buses
  • 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
  • Applications requiring MAN 341 Typ E4

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’s manual.

Features and benefits

  • Excellent load-carrying, anti-wear and extreme-pressure performance helps to protect against wear under harsh operating conditions throughout the transmission life
  • Outstanding protection against deposit formation contributes to longer seal life, and extended drain and service intervals
  • High protection from corrosion of copper and its alloys helps to protect and extend the life of synchronizers while delivering smoother shifting performance
  • Optimized 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
