Born and raised in Sioux City, KLS Diesel Services was founded on the principles of doing things right, for the right price. Being in the industry for years, Kevin Logsdon was tired of companies over charging his customers that he worked so hard to build relationships with. In 2025 Kevin decided that was going to end. With a drive to make customer partnerships that ensure that you can always stay running, and the expertise to match, KLS Diesel Services is here for you.
