- Product Highlights
- 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.
- 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 15W-40 has the potential to improve fuel economy².
- Exceptional oxidation stability³
- Excellent soot and viscosity control
- Excellent oil consumption control
- Outstanding TBN reserves
- Low temperature fluidity and pumpability
- Resistance to corrosive and abrasive wear
- Component compatibility
- Meets demanding specifications of key diesel OEMs
- Low ash formulation meeting API CK-4 and CJ-4 requirements
Note:
- ¹Results may vary based on vehicle/engine condition, driving and environmental conditions Consult OEM or ExxonMobil before implementing extended ODIs.
- ² Compared 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.
- Product Highlights
- Superior performance in extreme conditions and extended ODI service
- Greater engine efficiency, long engine life and long oil life
