Commercial Truck Supplies

Keeping commercial trucks on the road requires the right fluids, lubricants, and maintenance supplies. Keller-Heartt carries commercial truck supplies for fleet operators, repair shops, owner-operators, and heavy-duty vehicle maintenance teams, with products available in everything from cases and pails to 55-gallon drums and bulk totes.

Shop diesel exhaust fluid (DEF), heavy-duty motor oil, antifreeze and coolant, fuel and oil additives, hydraulic fluids, lubricants, cleaners, and fluid-handling equipment from brands including Truegard, Shell, BlueDEF, Peak, and other trusted manufacturers.

Diesel Exhaust Fluid for Commercial Trucks

Diesel exhaust fluid (DEF) is essential for diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. Maintaining a reliable supply of DEF helps keep emissions systems operating properly and commercial trucks on the road.

Keller-Heartt offers BlueDEF and other diesel exhaust fluid options in multiple quantities, including smaller containers, 55-gallon drums and 275- and 330-gallon totes for larger fleet operations. DEF pumps and dispensing equipment are also available for shops and facilities managing fluid in bulk.

Heavy-Duty Diesel Engine Oil

Commercial diesel engines operate under demanding conditions, making the right heavy-duty motor oil an important part of preventive fleet maintenance.

Keller-Heartt carries diesel engine oils and lubricants for commercial trucks and heavy-duty equipment, including Truegard and Shell products in multiple viscosity grades and container sizes. Fleet managers can purchase smaller quantities or stock maintenance facilities with pails, drums and bulk options based on usage.

Fuel & Oil Additives

Diesel fuel additives and oil additives can support specific maintenance needs, including cold-weather operation, fuel system performance and lubrication.

Keller-Heartt carries fuel treatments and additives for commercial diesel vehicles from brands including Power Service and other manufacturers. Product selection should be based on the fuel system, operating conditions and manufacturer's recommendations.

Fleet Lubricants & Maintenance Fluids

Commercial fleet maintenance extends beyond engine oil and DEF. Depending on the truck and equipment, maintenance programs may also require hydraulic oil, transmission fluid, gear oil, grease, brake cleaner and other specialty lubricants and fluids.

Keeping the appropriate products on hand can help maintenance teams perform scheduled service efficiently and reduce delays caused by waiting for frequently used fluids and supplies.

Buying Commercial Truck Fluids in Bulk

For fleets and commercial repair facilities, purchasing frequently used fluids in larger quantities can simplify inventory management and reduce the need for repeated small orders.

Keller-Heartt offers many commercial truck fluids in cases, pails, 55-gallon drums, 275-gallon totes and 330-gallon totes, depending on the product. Bulk options are especially useful for DEF, motor oil, coolant and other fluids used regularly across multiple vehicles.

Not sure how much product your operation needs? Keller-Heartt can help determine an appropriate product and container size based on your fleet and maintenance requirements.
