CountryMark produces a complete line of quality fuels, including Premium Diesel-R road diesel, Super Dieselex-4 off-road diesel and PLUS high-performance gasoline. CountryMark fuel products are unique.

CountryMark's all-American fuels begin with American crude oil, which contributes to America's energy independence, a stronger domestic economy and greater domestic energy security. As an added bonus, the crude is some of the highest quality crude oil in the world. CountryMark uses Illinois Basin crude, which is a light sweet crude oil. This type of oil results in higher value products that can be recovered with greater efficiences than heavy sour crude.
CountryMark also offers a full line of quality lubricants and energy equipment.
