Mobil Delvac™ – engine oil for heavy-duty engines
The product of ExxonMobil's 90-plus years' of expertise in developing lubricants for heavy-duty machinery, Mobil Delvac™ oils don't simply meet the requirements of today's commercial vehicle manufacturers and operators; they often surpass them.
With many of the world's leading heavy equipment engine builders selecting Mobil Delvac for factory and service fills, and endorsements for the brand coming from the major manufacturers of heavy commercial equipment, you can be sure that you'll get the best out of your vehicles by putting the best into them.
And no matter how complex the operating conditions, that means Mobil Delvac.
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 lubricants will also extend oil drain intervals, saving you both time and money.
Increased effectiveness at low temperatures
By maintaining low-temperature fluidity, Mobil Delvac 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 protection
Formulated to protect components from the adverse effects of soot and other pollutants, Mobil Delvac™ 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'.
