Our History

Beginning in 1976, Founders Ted and Marge Hoesli always dreamed of owning their own diesel repair shop and achieved just that along with their sons Dan and David Hoesli. Ted’s area of expertise was in Cummins diesel engines and Dan having just graduated from college with a degree in business got to work. After months of preparation they opened for business on October 4th, 1976 in Vanderburgh County and rightfully named it Ted Hoesli Diesel Service, Inc. located just north of Evansville in the community of Daylight, IN.

In merely ten years, the business had outgrown the first location and moved to a newer and larger facility on Hwy 57N about 2 miles up the road. In 1986, the business was sold to Ted’s eldest son Dan Hoesli which began the 2nd generation of Hoesli Diesel. Now in its 3rd generation, Dan’s son Erric is soon to take the reins of a company that has progressed into the most reputable diesel sales and service facility locally owned. Progressing as Hoesli Diesel Service, their expertise has encompassed not only diesel engines but to complete repair of Class 5 through Class 8 medium and heavy duty trucks, emergency response vehicles, fire trucks, RVs, and busses. Repairs and maintenance range from a basic oil change, to mandated DOT inspections up to complete engine overhauls. Hoesli Diesel also provides servicing for construction equipment both rubber tired and track, power units and fire-pumps. We have (4) four service field trucks for those repairs requiring off premises repairs. Lastly, Hoesli Diesel has become one of the largest generator sales, service and installation facilities in the Tri-State area featuring Generac and Onan brands.

Hoesli Diesel is proud to be a fully factory authorized dealer for engine manufacturers such as; Cummins Engine Co., Deutz Engine Co., Perkins Engines, Hatz Diesel, Detroit Diesel Corp. and Kubota Engines in sales, service and warranty.
