A Legacy of Trust and Authenticity

We opened some of America’s very first service stations in the 1920s, with our beloved DINO front and center, just as it is today. We’re honored to know that DINO remains a steadfast symbol of authenticity and trust across our country.


Sinclair Lubricants has stood the test of time, adapting to changes in engine design, fuel economy and customer needs. Our founder Harry Sinclair wrote the book “The Law of Lubrication” — it’s in our DNA.
