Certified Oil is one of EG America’s convenience and retail brands with more than 65 store locations across Ohio and West Virginia.

Our History 

In 1939, Carlyle Baker opened the first Certified Gasoline Station in Piqua, Ohio. The station sold gasoline and offered limited automobile repair to the motoring public. The three-generation family business was acquired in the spring of 2019 by EG Group, adding the locations to its portfolio of convenience store brands as part of its US operations.

Our Parent Company 

With more than 1,600 retail locations and 18,000+ team members across the U.S., EG America is one of the fastest-growing convenience store retailers in the country. As the operator of Certified Oil, Cumberland Farms, Fastrac, Kwik Shop, Loaf N’ Jug, Minit Mart, Sprint Food Stores, Tom Thumb, Turkey Hill, and Quik Stop stores, we are committed to becoming America’s preferred ‘one-stop’ destination by focusing on superior guest experience, high-quality grocery and fuel products, and supporting the communities we live and work in.

EG America is owned by EG Group, a UK-based fuel station and convenience store retailer, with locations across the UK, Europe, Australia, and the U.S.
