Mobil Delvac™ 1300 Super 10W-30 and 15W-40 are advanced diesel engine oils that help extend engine life, allowing you to run your business with confidence. These oils meet or exceed original equipment manufacturer (OEM) requirements and deliver high performance in both on- and off-highway applications.

Fully backward compatible, Mobil Delvac 1300 Super engine oils deliver exceptional performance in both newer and older heavy-duty engines. Its carefully tailored formulation provides:

  • Extended performance up to 50 percent beyond OEM-recommended oil drain intervals (ODIs)*
  • Excellent wear protection
  • Superior oxidation stability
  • Outstanding TBN retention

Developed in close collaboration with OEMs, Mobil Delvac 1300 Super engine oils are recommended for use in a wide range of heavy-duty applications and operating environments in the trucking, mining, construction, agricultural and marine industries. Accordingly, these oils also meet or exceed the requirements of API CK-4, CJ-4, CI-4 PLUS, CI-4 and CH-4 service categories, as well as key OEM requirements. Mobil Delvac 1300 Super engine oils are universal, meaning they may also be used in gasoline engines requiring the API SN specification.

Mobil Delvac 1300 Super diesel engine oils are recommended by ExxonMobil for use in:

  • The latest heavy-duty diesel engines, including those equipped with aftertreatment systems and EGR
  • Diesel applications using older and naturally aspirated conventional designs
  • On-highway heavy-duty trucking and off-highway applications including trucking, mining, construction, agriculture and marine
  • On-highway applications operating in both high-speed/high-load conditions and short haul pick-up/delivery service
  • Off-highway applications operating in severe low-speed/heavy-load conditions using up to 500 ppm sulfur fuels
  • High-performance gasoline engines requiring API SN and mixed fleet operations
  • Diesel-powered equipment from American, European and Japanese OEMs

Features and benefits

  • Extended performance up to 50 percent beyond OEM-recommended ODIs*
  • Excellent soot and viscosity control enables greater engine efficiency, long engine and oil life†
  • Excellent thermal and oxidation stability helps reduce engine deposits and sludge buildup to keep engines running reliably
  • Enhanced TBN reserves improves corrosion protection and extends drain intervals for both newer and older heavy-duty engines using either low (500ppm) or ultra-low (15ppm) sulfur diesel fuel
  • Stay-in-grade shear stability, excellent low-temperature pumpability along with superb corrosive and abrasive wear resistance provide greater wear protection to help prolong engine life
  • Excellent oil consumption control requires less makeup oil during operation, which helps lower oil costs
  • Meets demanding specifications of key OEMs and latest API gasoline service category, and allows for use of single engine oil for mixed-fleet operations

*Results may vary based on vehicle/engine condition, driving and environmental conditions. Consult OEM or ExxonMobil before implementing extended ODIs.
†Well-formulated oils, like Mobil Delvac™, that meet or exceed industry or OEM specifications, can help protect engines. Consult OEM for optimum fluid selection. Actual results may vary depending on OEM requirements, type of engine and its maintenance, application and service conditions, and prior lubricant used. For more information, go to mobil.com/pds.
