Keller-Heartt Oil

Keller-Heartt Oil Co. is a Shell Prestige Distributor — placing us in the top 5% of Shell distributors nationwide — and a family-owned supplier of industrial lubricants, oils, and chemicals headquartered in Chicago. In business since 1929, Keller-Heartt has spent nearly a century building the relationships, inventory infrastructure, and technical expertise that businesses depend on to keep their operations running.

We distribute premium products from leading brands including Shell, Pennzoil, BlueDEF, Fuchs, Houghton, Oil Eater, and WD-40, alongside our own Truegard private-label line, engineered to deliver 1:1 equivalent performance to name-brand products at a significantly lower cost. From 55-gallon drums of hydraulic oil and metalworking fluid to bulk diesel exhaust fluid (DEF) and food-grade propylene glycol, our catalog covers the full spectrum of lubrication, chemical, and fluid-management needs.

With over $8 million in inventory across distribution centers in Chicago and Milwaukee, we fulfill bulk orders nationwide with free shipping on every order and no minimum purchase requirement. Our customers include trucking fleets, machine shops, manufacturers, food and beverage processors, automotive service providers, aviation operators, and government agencies at every level.

What sets Keller-Heartt apart is simple: we pair nearly 100 years of industry knowledge with the convenience of modern B2B e-commerce. Our team provides personalized technical guidance, volume pricing, and B2B account programs built to simplify procurement for businesses of every size.
