Our trucks can be frequently seen cruising along on delivery runs. The business itself has been a entity since 1928, passing through various name changes and expansions. It is still a family owned and operated business.

It began in 1928 as the Pierron Oil Co. Carl Lammers came on board with the crew in 1968. John Meckles of Staunton purchased the company in 1973 and renamed it the Highland Pierron Oil Company. Carl bought the business five years later. Carl and his wife, Helen, worked at the business until they retired in 2007 and 2006, respectively. Their son, Terry, took his place within the family business in 1991 after graduating from Webster University and working for a brief time in St. Louis. The business became incorporated in 1991 and was named Tri-County Petroleum, Inc. In 2006, Terry's wife, Julie, came to work for the company as well.

Currently, Tri-County Petroleum has 3 offices located in Pierron, Vandalia and Wood River with Pierron being the headquarters. The company focuses on four industries: agricultural, trucking, construction/ excavating and industrial. The business area covers 14 counties in Central and Southern Illinois and Metro St. Louis.

Tri-County Petroleum currently runs a fleet of delivery trucks, ranging in size from 2,000 to 4,400 gallons. The company has over 500,000 gallons of gasoline and diesel fuel storage at bulk plants located in Pierron, O'Fallon, Vandalia, Hamel and Greenville and over 50,000 gallons of lubricant storage at the bulk plant in Wood River.
