TRUEGARD Automotive Low Tox: 100% Concentrate Propylene Glycol - 55 Gallon Drum

This product uses a propylene glycol base instead of the ethylene glycol found in conventional antifreeze. Propylene glycol is significantly less toxic, providing an added margin of safety for pets and wildlife in the event of accidental ingestion - an important consideration in garages, farms, or any environment where animals may be present.

Yes, as a 100% concentrate it must be mixed with water before use and is not ready to use straight from the drum. Refer to the product datasheet for the recommended dilution ratio and the corresponding freeze and boil-over protection ranges.

This formula is intended for automotive engines and light duty truck applications. It is not specified for heavy-duty diesel engines or commercial fleet vehicles, so buyers with those needs should verify compatibility with a product rated for those systems.

The universal designation means the formula is engineered to provide excellent protection across all automotive and light duty truck makes and models, rather than being specific to a single vehicle brand or cooling system type. This makes it practical for shops or fleets servicing a variety of vehicles.

A 55-gallon drum is best suited for high-volume users such as automotive service shops, dealerships, or fleet maintenance operations that perform frequent coolant fills or changes. The listing notes that bulk sizes are available, suggesting smaller package options may also exist for lower-volume needs.
