Mobil Delvac 1 5W-40

Mobil Delvac 1 utilizes state-of-the-art technology to deliver exceptional performance in modern low emission engines, including refrigerated units, as well as older, well-maintained engines.

Mobil Delvac 1 5W-40 is recommended for use in a wide range of heavy-duty applications and operating environments found in the on-road transport and off-road mining, construction, and agricultural industries. Mobil Delvac 1 also meets the API SL specification for gasoline engines used in mixed fleets.

The unequalled performance of Mobil Delvac 1 5W-40 is the result of extensive cooperative development work with major equipment builders and application of the latest lubrication technology. As a result, this product meets or exceeds the latest API, ACEA, JASO, and Global industry specifications for diesel engine oils, as well as the requirements of virtually all major American, European, and Japanese engine manufacturers.

Features and Benefits

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for supreme performance lubricants. Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives.

Top piston rings are located higher, bringing the oil film closer to the combustion chamber and exposing the lubricant to severe thermal stresses. Mobil Delvac 1 5W-40 maintains outstanding performance at significantly higher temperatures than other high performance diesel engine oils. It is also fully compatible with conventional oils.
