It distributes gasoline under the Kwik Fill and Keystone brands. In early 2019, the American Automobile Association noted that Warren had the most expensive gasoline in Western Pennsylvania, despite the presence of the refinery in the town and a gasoline station just outside the refinery, the root cause of which remains undetermined.
