Mobil Delvac™ 1300 Super

High Performance Diesel Engine Oil
Mobil Delvac™ 1300 Super 15W-40 and 10W-30 are advanced diesel engine oils that help extend engine life, allowing you to run your business with confidence. These products 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 delivers exceptional performance in both newer and older heavy duty engine designs. Accordingly, these oils 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 oils are universal, meaning they may also be used in gasoline engines requiring the API SN specification.

Mobil Delvac 1300 Super is a tailored formulation that delivers excellent wear and engine protection, extended drain capability, outstanding high temperature performance and engine cleanliness. Developed in close collaboration with major OEMs, Mobil Delvac 1300 Super is recommended for use in a wide range of heavy duty applications and operating environments in the trucking, mining, construction, agricultural and marine industries.

Mobil Delvac 1300 Super is formulated with optimized base oil technology, containing severely hydro-processed base stocks and a tailored additive system to deliver extended performance for up to 1.5x beyond OEM-recommended oil drain intervals1. This proprietary formulation delivers excellent wear protection, outstanding oxidation stability, and outstanding TBN retention. Mobil Delvac 1300 Super also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits. 

Mobil Delvac 1300 Super 10W-30 has the potential to improve fuel economy2.

The key benefits include:

FeaturesAdvantages and Potential Benefits
Meets demanding specifications of key OEMs and latest API gasoline service categoryOne engine oil for mixed fleet operations
Outstanding oxidation stabilityExtended ODI capability. Reduced low temperature sludge build-up and high temperature deposits
Excellent soot and viscosity controlGreater engine efficiency, long engine life and long oil life
Excellent oil consumption controlLower oil costs due to less make-up oil during operation
Outstanding TBN reservesCorrosion protection and extended drain intervals for both new and old engines using up to 500 ppm sulfur diesel fuel
Low temperature fluidity and pumpabilityFormulated for smooth starting in cold weather
Resistance to corrosive and abrasive wearLong life of critical wear surfaces
Component compatibilityLong gasket and seal life
Low ash formulation meeting API CK-4 and CJ-4 requirementsLong emissions after treatment life (DPF, DOC and SCR)

1Results may vary based on vehicle/engine condition, driving and environmental conditions Consult OEM or ExxonMobil before implementing extended ODIs.

2Compared to a SAE 15W-40 conventional engine oil. Savings are dependent on vehicle engine type, outside temperature, driving conditions, and your current engine oil viscosity.


  • Recommended for the latest heavy duty diesel engines, including those equipped with aftertreatment systems and EGR.
  • Recommended for 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 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.
