Our commitment to industry leadership began in 1926 when two ambitious men, Jim Wills and Harold Swann, acquired the La Plata Oil Company and Mechanicsville Oil Company, and merged the companies to form Southern Maryland Oil Company (SMO). The newly formed company distributed products and pledged “courteous and efficient service.” In the early days, Southern Maryland Oil handled only three Texaco products: kerosene, gasoline, and motor oil. But by 1937, with the invention of the gun type burner, fuel oil became a hot commodity and created an ever-increasing market for home heating. SMO began deliveries on an automatic basis – the first such service available to clients in Southern Maryland.
The founders had no idea that SMO would grow into the largest business of its kind in the region – let alone one of the largest family-run businesses in the state. The only dream for SMO was to be recognized for great customer service. And now over 90 years later, the company’s founding principle of customer centricity is a continued hallmark that can be observed in years and decades of continued service and repeat clients.
Throughout our 90 years, we have diversified into other areas of operation along the way, under our parent company, The Wills Group. Our sister companies include Dash In convenience stores, Splash In, and SMO Motor Fuels, which serve gas stations and commercial clients across the region.
We are proud to be a locally operated and family owned business rooted in Southern Maryland. We provide high-quality products with “courteous and efficient service” and we look forward to serving our clients for many years to come.
