Synthetic Diesel Engine Oil

Product Description

Mobil Delvac Modern™ 10W-30 Fuel Efficient is a synthetic diesel engine oil that helps extend engine life, allowing you to run your business with confidence. It meets or exceeds the new API FA-4 specification for fuel efficient engine oils as well as key original equipment manufacturer (OEM) requirements.


Mobil Delvac Modern 10W-30 Fuel Efficient is engineered to deliver potential fuel economy benefits1 beyond those typically provided by SAE 10W-30 engine oils. This product is a tailored formulation that delivers excellent wear and engine protection, extended drain capability, outstanding high temperature performance and engine cleanliness. Developed in close collaboration with major OEMs, Mobil Delvac Modern 10W-30 Fuel Efficient is recommended for use in heavy duty applications and operating environments found in the on-road trucking industry.


Mobil Delvac Modern 10W-30 Fuel Efficient 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 is formulated with synthetic oil, containing hydro-processed base stocks and a tailored additive system to deliver extended performance for up to 50% beyond OEM-recommended oil drain intervals¹. The proprietary formulation delivers excellent wear protection, superior oxidation stability, and outstanding TBN retention. Mobil Delvac Modern 10W-30 Fuel Efficient also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.


Mobil Delvac Modern 10W-30 Fuel Efficient is engineered to provide greater potential fuel economy benefits than typical SAE 10W-30 oils².
