CountryMark Refinery

The CountryMark refinery was built in Mount Vernon, Indiana, in 1940 by farmers who had a vision of energy security and independence.
The refinery is supplied with crude oil from the Illinois Basin through a system of approximately 500 miles of pipeline, which gathers the crude oil from thousands of oil wells owned by area farmers and landowners.
The refinery operates 24 hours per day, 365 days per year. Refinery capacity averages 26,800 barrels of crude processed per day.
From the refinery, CountryMark refined fuels travel to fuel terminals in Mt. Vernon, Switz City, Jolietville and Peru, Ind. CountryMark strictly controls all proprietary fuels to ensure that the highest quality standards are maintained.
The Illinois Basin – Naturally Sweet Crude
The CountryMark refinery uses 100% American crude oil sourced from the Illinois Basin, a 53,000 square mile depression underneath southern Illinois, southern Indiana and western Kentucky.
Illinois Basin crude oil is of higher quality than crude from the Middle East. It naturally contains less sulfur, which contributes to processing ease and product quality. It also refines better, yields diesel with a higher cetane rating and produces more gasoline and diesel fuel from each barrel.
By sourcing American crude oil, we reduce our reliance on foreign oil while dollars spent for this oil remain here in the Midwest where they support our local economies.
