Synthetic Technology

Product Description

Mobil Delvac Modern 15W-40 Complete Protection is an extra high performance synthetic technology diesel engine oil that helps extend engine life in the most severe on and off-highway applications while delivering outstanding performance in modern, high-output, low-emission engines including those with Exhaust Gas Recirculation (EGR) and Aftertreatment Systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). Fully backwards compatible, Mobil Delvac Modern 15W-40 Complete Protection will also deliver the same exceptional performance in older conventional engines. As a result, it meets or exceeds the requirements of API CK-4, API CJ-4, API CI-4 PLUS, API CI-4 and API CH-4 service categories as well as key Original Equipment Manufacturer (OEM) requirements.


Mobil Delvac Modern 15W-40 Complete Protection is the result of extensive cooperative development work with major OEMs and is recommended by ExxonMobil for use in a wide range of heavy-duty applications and operating environments found in the trucking, mining, construction, quarrying, and agricultural industries. This product provides outstanding protection in the most demanding diesel engines of Caterpillar, Cummins, Detroit, Mack, Renault, Volvo.
