Mobil Delvac™ Extreme  

Mobil Commercial Vehicle Lube, United States

Premium Synthetic Diesel Engine Oil

Product Description

Mobil Delvac™ Extreme 15W-40 and 10W-30 are premium synthetic, 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.

Fully backward compatible, Mobil Delvac Extreme 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 original equipment manufacturer (OEM) requirements.

Mobil Delvac Extreme is a boosted formulation designed for extended oil drain service and operations in extreme conditions. It delivers unsurpassed high temperature performance under the extreme operating environments found in the trucking, mining, construction, and agricultural industries.

 

Features and Benefits

Mobil Delvac Extreme is formulated with synthetic basestocks and a boosted additive system tailored to deliver extended performance for up to two times beyond OEM recommended oil drain intervals1. The proprietary formulation delivers excellent wear protection, exceptional oxidation stability2, and outstanding TBN retention. Mobil Delvac Extreme FE also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.

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

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

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

3Based on performance in the Volvo T-13 engine test.

 

Applications

•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.
