Advanced full synthetic, high-performance diesel engine oils

Mobil Delvac 1 ESP 0W-40, 5W-30 and 5W-40 are advanced full synthetic, high-performance diesel engine oils that deliver long drain capability and fuel economy potential* while helping to extend engine life for modern diesel engines operating in severe conditions.

Mobil Delvac 1 ESP diesel engine oils are formulated to deliver exceptional performance in newer and older engine designs, including those with emission control systems. Their proprietary formulation meets or exceeds the requirements of original equipment manufacturers (OEMs) with state-of-the-art technology that provides:

  • Outstanding performance at extreme temperatures
  • Our best protection for drivers with extended oil drain intervals
  • Enhanced emissions systems protection in a variety of severe conditions

Mobil Delvac 1 ESP diesel engine oils are recommended by ExxonMobil for use in:

  • Most engine generations up to the latest and most sophisticated high-performance diesel engines with turbocharger, direct-injection and low-emission designs
  • On-highway applications operating in both high-speed/high-load and short-haul pick-up/delivery
  • Off-highway applications operating in severe low-speed/heavy-load conditions
  • High-performance gasoline engines and mixed fleets
  • Heavy-duty diesel engines using low-sulfur diesel fuels and many biodiesel fuel formulations
  • Naturally aspirated and turbocharged, diesel-powered equipment
  • Virtually all diesel-powered equipment from American and European builders
  • Refrigeration units

Features and benefits

  • Formulated with advanced synthetic base stocks to help improve fuel economy*
  • Excellent oxidation performance that helps reduce engine deposits to keep engines running reliably
  • Excellent anti-wear and anti-scuff properties help control wear in heavy-duty operation to help promote long engine life
  • Excellent low-temperature performance allows for increased oil flow to critical bearing surfaces at startup and controls low-temperature sludge formation in stop-and-go service
  • Outstanding protection against oil thickening and degradation contributes to long drain interval capability, helping to reduce the number of oil changes and oil disposal needs

*Compared to an SAE 15W-40 engine oil. Actual savings are dependent on vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity.
