The history of Mobil Delvac™
In its 90-year history, Mobil Delvac™, one of the world’s first diesel engine oils, has responded to the trucking industry’s ever-evolving needs with continued innovation and performance. For the pioneering efforts of early owner/operators and today’s large and sophisticated fleets, Mobil Delvac has been there. It’s been a twisting, turning ride full of challenges met and obstacles overcome. As we look back on our history, we also look forward to the road ahead — and to keeping trucks on it.
1892 - Invention of the diesel engine
German engineer Rudolf Diesel files for patent on a revolutionary compression-ignition engine that will be named after him.
1925 - Delvac™ is born
To help address the high pressure and heat generated in diesel engines, scientists at Vacuum Oil, a predecessor firm of ExxonMobil, devised a special oil formulation. Vacuum Oil registered the product in 1925 as Diesel Engine Lubricant by Vacuum Oil, or DELVAC. The Mobil Delvac brand was officially born.
1930s - The first trucking boom
The increase of roads, along with growing use of pneumatic tires and diesel engines in commercial vehicles, creates the first boom in the trucking industry.
1940s - Diesel dominates the road
The diesel engine’s performance during World War II popularizes its use in commercial vehicles in the post-war years. As one of the first oils designed specifically for diesel engines, Mobil Delvac is used by many truckers.
1956 - Highways connect the world
The U.S. government approves the Federal Highway Act, funding construction of 41,000 miles of highway. Three years later, the United Nations initiates the Asian Highway Project to help create roads linking Asian countries to each other and to Europe. These massive highway projects spark dramatic growth in the trucking industry.

The Mobil Delvac brand is officially registered in Russia. The first staffed ExxonMobil office in Russia, however, will not open for another 20 years, in 1994.
