The History of Mobil Delvac

Mobil 90 years logo

A lot of things have changed since 1925, when Mobil Delvac became one of the world’s first diesel engine oils. Our commitment to the trucking industry, however, has remained very much the same. In its 90-year history, Mobil Delvac has responded to the industry’s ever-evolving needs with continued innovation and performance.
From the pioneering efforts of early owner/operators to today’s large and sophisticated fleets, from the days of dirt roads to our era of super highways, Mobil Delvac has been there to help the industry advance. It’s been a twisting, turning ride full of challenges met and obstacles overcome. As we look back on our history in the timeline below, we also look forward to the road ahead — and to keeping trucks on it.
