Mobil Delvac 1™ Transmission Fluid V50

Mobil Commercial-Vehicle-Lube , United States

Mobil Delvac™ 1 Transmission Fluid V50 is a fully synthetic, heavy duty manual transmission lubricant engineered to meet demanding requirements. Recommended by ExxonMobil for year-round lubrication of manual transmissions requiring Volvo 97315 or Volvo 97319 type oils (refer to owner's manual recommendation) for on-highway commercial medium and heavy duty trucking, including vocational applications, heavy load hauling, and frequent PTO usage. Designed to provide excellent performance, Mobil Delvac 1 Transmission Fluid V50 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 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 V50 is recommended for manual transmissions and non-hypoid gear-box applications.
