CountryMark’s refinery was built in Mount Vernon, Indiana in 1940, shortly after a local gusher well was discovered nearby. The farmer owners who built the 2,000 barrel-per-day refinery had a vision of energy security and independence, and a commitment to manufacture high quality fuels that would deliver value though power, performance and protection.
Today, the CountryMark refinery processes 27,000 barrels of American crude oil per day, operating 24 hours per day, 365 days per year. The CountryMark refinery brings to the market 450 million gallons of finished fuel products per year. CountryMark is proud to be a reliable supplier of market-leading energy products and services for farms, fleets and families in Indiana, Illinois, Michigan, Ohio and Kentucky.
CountryMark is unique in that 100% of the crude oil refined at CountryMark is sourced from the Illinois Basin, which includes southern Illinois, southern Indiana and western Kentucky. Transport trucks and a network of pipelines stretching 400 miles bring local crude oil into the refinery. American crude oil that is locally refined provides a dependable source of domestic energy, which aides in domestic energy independence and security.
