Product Highlights
  • It has the same viscosity as most SAE 50 engine oils and SAE 90 gear lubricants at the high end of the temperature-viscosity scale, and because of its inherently high viscosity index, it provides stronger film strength at higher temperatures than conventional oils.
  • Mobil Delvac 1 Transmission Fluid 50 also ensures effective lubrication at below freezing temperatures without channelling.
  • Excellent load carrying, anti-wear, and EP performance
  • Outstanding protection against deposit formation
  • Maximum protection from corrosion of copper and its alloys
  • Optimized thermal and oxidation protection
  • Exceptional shear stability
  • Outstanding low-temperature fluidity
  • Extended drain and service interval capability
Product Highlights
  • Extends transmission life and reduces cost of operation
  • Longer seal life, extended drain and service intervals
  • Protects and extends the life of synchronizers
  • Extends component life and improves efficiency
  • Minimizes wear during severe operation
  • Reduces wear during cold temperatures and improves shifting with quicker starts
  • Provides lower operating costs and higher productivity
