Quality Diesel Engine Repair From Professional You Can Trust

Backed by a long history of quality and expertise, Thompson Diesel Inc. was founded by Brothers Raymond and James Thompson in 1970, in Oklahoma City. Shortly after, our Tulsa facility opened in 1973, as business continued to boom. In 1992, Raymond Thompson retired, leaving the business to James Thompson, who recently retired in 2011. The current owners of the business are Al Johnston and Everett and Linda Stacy, who have more than 100 years combined experience in the fuel injection and turbocharger business.
