Keller Heartt has been a full-service oil and lubricant provider in the Midwest, for over 80 years. As a privately owned family company, we have grown into one of the leading distributors of bulk oil solutions in the country. With distribution centers in both Chicago and Milwaukee, we now ship everywhere in the continental United States.

Thanks to our long-standing history, we've grown our distributor partnerships over time, securing some of the lowest wholesale prices online for leading brands like Shell, WD-40, American Lubrication, Houghton, Oil Eater and more.

Keller Heartt is also home to TRUEGARD lubricants, one of the industry's most affordable lubricant brands. Our full line-up features bulk sizes of everything from brake cleaner and hydraulic oil to motor oil and propylene glycol, all only a call away.
