Mobil Delvac™ Extreme

Mobil Delvac™ Extreme 15W-40 and 10W-30 are premium synthetic-blend, high performance, diesel engine oils that help extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions. They are recommended for use in a wide range of heavy-duty applications and operating environments found on-and off-highway, including engines operating under heavy loads.

 

 

FeaturesAdvantages and Potential Benefits
Exceptional oxidation stability1Superior performance in extreme conditions and extended ODI service
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
Meets demanding specifications of key diesel OEMsOne engine oil for mixed diesel fleets
Low ash formulation meeting API CK-4 and CJ-4 requirementsLong emissions aftertreatment life (DPF, DOC and SCR)


1Based on performance in the Volvo T-13 engine test

 

  • Recommended for the latest heavy duty diesel engines operating in extreme conditions, 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.
  • Diesel-powered equipment from American, European and Japanese OEMs.
