Why Mobil Delvac?

The reason Mobil Delvac™ is chosen by the world’s leading OEMs and many Owner Operators is quite simple – its proven record and leading edge technology. Our comprehensive range is led by Mobil Delvac 1™ ESP 0W-40, an advanced synthetic supreme performance low-ash diesel engine oil that helps extend both engine and emission system life, while providing long drain intervals and fuel economy potential in modern diesel engines.


Mobil Delvac™ synthetic engine oils are designed to lubricate and protect modern low-emission engine designs. These designs often include low oil consumption rates, use of Exhaust Gas Recirculation, Selective Catalytic Reduction and sometimes Diesel Particulate Filters.

For Commercial Vehicles fitted with Diesel Particulate Filters, we have developed a range of outstanding low-ash synthetic oils.

Exhaust Gas Recirculation (EGR) Engines and their Challenges

As heavy-duty diesel emissions standards for nitrogen oxides (NOx), solid matter, hydrocarbons, and carbon monoxide become stricter, OEMs have found innovative ways to meet those requirements while still meeting customer needs for power and efficiency.

In order to lower the level of NOx in the exhaust, OEMs began incorporating exhaust-gas-recirculation (EGR) systems into their new engine’s designs. Although each manufacturer’s EGR system is different, in outline, EGR works by recirculating exhaust gas, metered and controlled by the electronic management system, back into the intake system. This increases the challenge for the engine oil due to the need for greater soot, heat, deposit and corrosion control.


The reliability, performance and lifetime of your vehicle’s driveline ultimately depends on an extremely thin lubricant film that separates moving parts and reduces friction. By selecting the right Mobil Delvac™ Synthetic engine oil from our range, you will help to protect your engine from the harmful effects of soot and other contaminants. Mobil Delvac™ technology helps maximize the life of heavy-duty equipment, whether it’s used in advanced low-emissions engines or hard-working older engines.
