diesel exhaust fluid, heavy-duty motor oil, antifreeze and coolant, fuel and oil additives from brands including Truegard, Shell, BlueDEF, Peak, and other trusted manufacturers.

 


 

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.

Antifreeze & Coolant

The right heavy-duty antifreeze and coolant helps regulate engine temperature while protecting cooling systems against freezing, overheating and corrosion.

Our commercial truck fluid selection includes products such as ShellZone DEX-COOL and other antifreeze products to DEF pumps, storage equipment and related supplies for diesel engines and fleet applications. Always follow the vehicle or engine manufacturer's specifications when selecting or changing coolant.

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.

Frequently asked questions

Find answers to common questions about our products and services

  • Maintenance requirements vary by vehicle, but common commercial truck fluids include diesel engine oil, diesel exhaust fluid (DEF), antifreeze and coolant, transmission fluid, gear oil, grease and other lubricants. Always follow the manufacturer's maintenance schedule and fluid specifications for each vehicle.

  • Diesel exhaust fluid is used by diesel vehicles equipped with SCR emissions systems. DEF is injected into the exhaust system to help reduce nitrogen oxide emissions. It is stored separately from diesel fuel and should never be added to the fuel tank.

  • Yes. Keller-Heartt carries DEF in several sizes, including options designed for commercial fleets and high-volume users. Depending on the product, this can include 55-gallon drums and 275- or 330-gallon totes, along with DEF pumps and dispensing equipment.

  • A good fleet fluid program starts with identifying the specifications and service intervals for each vehicle. Frequently used products such as motor oil, DEF and coolant can then be stocked in appropriate quantities, while less frequently used fluids can be purchased as needed.

  • Yes. Keller-Heartt carries commercial vehicle fluids and maintenance products in multiple sizes, including cases, pails, drums and bulk totes. This allows businesses to purchase based on the size of their fleet and expected fluid usage.
