Mobil Delvac 1™ – high-performance engine oils for heavy-duty engines

Mobil Delvac 1™ is a fully synthetic engine oil that helps extend the life of heavy- duty diesel engines, increase service intervals and reduce fuel consumption. The product of innovation, expertise and technological advances, Mobil Delvac 1 is formulated to ensure modern low-emission engines operate at maximum efficiency.Mobil Delvac heavy-duty products are recommended for equipment operating in the harsh environments and severe conditions typical of transport, mining, construction and agricultural industries.
Better Fuel Economy

Better fuel economy

Fuel bills represent a significant part of commercial vehicle running costs. But compared to mineral oils, using Mobil Delvac 1 synthetic lubricants, used in combination with synthetic gear oils and greases, provides a substantial saving.

Improved High Temperature

Improved high-temperature performance

Our synthetic lubricants exhibit exceptional stability at high temperatures. It means that they are more resistant to thermal degradation, which can cause the formation of sludge and deposits, as well as changes in viscosity that adversely affects engine efficiency. Using synthetic Mobil Delvac 1 lubricants will also extend oil drain intervals, saving you both time and money.

Increase Effectiveness

Increased effectiveness at low temperatures

By maintaining low-temperature fluidity, Mobil Delvac 1 synthetic lubricants have the power to reduce internal friction and maintain performance. Keeping engine components lubricated – especially after a cold start, which is one of the main causes of engine wear – will also help prolong engine life.

Outstanding Engine

Outstanding engine protection

Formulated to protect components from the adverse effects of soot and other pollutants, Mobil Delvac 1™ lubricants will help maximize the life of the engines driving all commercial vehicles and heavy-duty equipment – from modern low emission designs to the older 'workhorse'.

Greater Environmental Protection

Greater environmental protection

In terms of environmental impact, the modern low emission engines Mobil Delvac 1 synthetic products are designed to lubricate and protect, are often as oil efficient as fuel-efficient. In most cases, they are equipped with exhaust gas recirculation (EGR), selective catalytic reduction systems (SCR) and Diesel Particulate Filters (DPF). For commercial vehicles equipped with DPF-filters, we offer a low-ash synthetic oil with excellent performance.
