Mobil commercial-vehicle-lube , 中国

Full Synthetic Commercial Vehicule Engine Oil

Product Description

Mobil Delvac MX™ ESP 10W-40 is an extra high performance diesel engine oil that helps extend engine life in 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). Mobil Delvac MX™ ESP 10W-40 also delivers the same exceptional performance in older conventional engines.


Mobil Delvac MX™ ESP 10W-40 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 demanding diesel engines.


Features and Benefits

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