Lange Oil first began in 1982 when Ken and Marlene Lange purchased Holmen Oil. Bulk petroleum was the core of the business which served many local farmers and home-owners. Darren and Tamara joined the business in 1993 when Lange Oil upgraded from a full-service gas station to a self-serve convenience store. In 2003, Lange’s changed from the Texaco brand to Shell and remains that today.
