Motor Oil

Whether you’re buying for a corporate fleet or for construction equipment, you need the right oil to protect your engines in normal operating conditions, as well as in extreme cold. 

Keller-Heartt offers a wide selection of motor oil, including the bestselling Shell Rotella T4 Triple Protection 15W-40 Heavy Duty Motor Oil and its equivalent alternative—Truegard 15W40 Motor Oil. If you determine that Truegard® can work in your vehicles, you could save yourself somewhere in the neighborhood of 40% on your oil costs.

Propylene Glycol

Propylene glycol is a versatile fluid used for industrial applications like antifreeze. It is also used in the food service industry as a preservative and flavor enhancer, and even for making ice! Keller-Heartt’s Truegard® propylene glycol passes the same stringent analysis as Dow’s DOWFROST™ but is a fraction of the price. It is also available in both the industrial-grade and the food-grade varieties.

Ethylene Glycol

Ethylene glycol can be applied to everything from wing deicers to HVAC systems, house paint, pharmaceuticals, and even cosmetics. With Keller-Heartt, you can purchase Truegard® ethylene glycol in either the uninhibited or inhibited formulation (inhibited has greater corrosion protection), and it compares closely to DOWTHERM™.

Cutting Oil

Cutting oils can be used as coolants for heavy-duty machining and grinding, protecting against corrosion and wear as a lubricant, and as a flushing fluid. We offer multiple affordable options, including our popular Truegard Soluble 100 Oil

Brake Cleaner

Beyond cleaning brakes and metal components like screws and nuts, brake cleaner can remove just about any stain you find in your house or garage—including those from permanent markers, paint, and nail polish. Keller-Heart offers Truegard Non-Chlorinated Brake Cleaner at a price that will beat the national brands.


Whether you’re thinning chemicals, using solvents as a degreaser, or using them for pharmaceutical manufacturing purposes, Truegard Mineral Spirits Safety Solvents—142 Flash Point is a staple of machine shops, garages, and factories nationwide.


Antifreeze does so much more than its name implies. Beyond keeping engine temperatures stable, it protects against corrosion and lubricates moving parts too. Truegard has solutions for many applications:

Anti-Wear Hydraulic Oil

Truegard hydraulic oils help improve the performance of your hydraulic systems and overcome tough operating conditions. Truegard comes in three sizes—5-gallon pails, 55-gallon drums, and 330-gallon totes—and in three weights:
