Synthetic Diesel Engine Oil

Product Description

Mobil Delvac Modern 10W-30 Fuel Efficient Plus  is a  synthetic, high performance, diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions. It meets or exceeds the new API FA-4 specification for fuel efficient engines oils as well as key original equipment manufacturer (OEM) requirements.


Mobil Delvac Modern 10W-30 Fuel Efficient Plus  is a boosted formulation designed for extended oil drain service and operations in extreme conditions. Developed in close collaboration with major OEMs, it is recommended for use in the extreme applications and operating environments found in the on-road trucking industry.


Mobil Delvac Modern 10W-30 Fuel Efficient Plus should only be used where an API FA-4 oil is recommended by the OEM. Before using this product in an engine, users should consult recommendations as shown in an owner's manual or other service bulletins.


Features and Benefits

Mobil Delvac Modern 10W-30 Fuel Efficient Plus  is formulated with a blend of synthetic basestocks and a boosted additive system tailored to deliver extended performance for up to 2X beyond OEM recommended oil drain intervals¹. The proprietary formulation delivers excellent wear protection, unsurpassed oxidation stability², and outstanding TBN retention. Also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.


Mobil Delvac Modern 10W-30 Fuel Efficient Plus is engineered to provide greater potential fuel economy benefits than typical SAE 10W-30 oils .
