Our History

In 1955, Ralph Trejo bought the Shell Oil Bulk Plant in Casa Grande, Arizona where he and his family remained for many years. During this time he founded Trejo Oil Company which is still operated by his two sons, Jon and Jerry.

Since that time the company has grown to provide over fifty million gallons of fuel products a year to customers in three states, as well as operating twenty retail fuel locations, & a fleet of fuel transportation trucks servicing four states.

The company has since relocated to Mesa, Arizona, to better serve it's fuel wholesale, retail, and transportation customers.
