Mobil commercial-vehicle-lube , South Korea

Fully Synthetic

Product Description

Mobil Delvac Modern™ 10W-40 Full Protection is an extra high performance fully synthetic 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 10W-40 Full Protection will also deliver the same exceptional performance in older conventional engines. It meets or exceeds the requirements of the API CK-4, CJ-4 service categories as well as key Original Equipment Manufacturer (OEM) requirements.


Features and Benefits

Mobil Delvac Modern 10W-40 Full Protection is formulated and a mixed detergent system to deliver cutting-edge performance in both new and older engines. In addition to assuring excellent control of oil thickening due to soot build-up and outstanding TBN retention for long drain intervals, Mobil Delvac Modern 10W-40 Full Protection's advanced technology also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.


The key benefits include:
