MFA Oil Co. is a farmer-owned cooperative with more than 40,000 members that was organized in 1929 by Missouri farmers who were seeking assurance of a reliable and quality supply of fairly-priced petroleum products. The company has been serving local consumers' needs since that time, becoming the largest supplier of propane in Missouri and creating the Break Time convenience stores in 1985 through its subsidiary, MFA Petroleum, which also operates the Big O Tire and Jiffy Lube franchises in mid-Missouri. In addition to propane, MFA Oil also sells fuels and lubricants to customers in Missouri, Arkansas, Kansas, Indiana, Kentucky, Oklahoma and Iowa.

The top three categories are lottery, cigarettes, and packaged beverages.
