Lubegard 96430 Coolant Treatment, 32 fl. oz.

Outperforming all other supplemental coolant additives (SCAs) by a significant margin, Lubegard Heavy Duty Coolant Treatment stands in a league of its own. The Penray PenCool 2000, PenCool 3000, Cummins Fleetguard DCA-4, and Lubegard HD coolant treatment were all subjected to ASTM certified tests for corrosion protection performance, including ASTM D4340, ASTM D1384, and ASTM D2570. While all products except for the PenCool 2000 passed these tests, the Lubegard 2-in-1 heavy duty coolant treatment excelled with the most margin, offering aluminum protection with cutting-edge organic technology.

Unlike its competitors, Lubegard contains no phosphate and has received universal OEM acceptance. Its wetting agent ingredients deliver superior engine temperature reduction performance, eliminating the need for additional products like Red Line diesel water wetter, which has been shown to create a harmful layer of slime in radiators due to its polysiloxane content.

By combining complete corrosion protection and wetting agents in one product, Lubegard streamlines the maintenance process and chemically reduces coolant surface tension to enhance heat transfer efficiency. This innovative formula is free of ethylene glycol and offers 2-in-1 corrosion protection and temperature reduction, ensuring long-lasting protection against corrosion, chemical electrolysis, cavitation erosion of wet sleeve cylinder liners, overheating-causing scales, deposits, and slime buildup, as well as extending the lifespan of water pump impellers and seals.

Overall, Lubegard Heavy Duty Coolant Treatment leads the pack in performance, safety, and efficiency, making it the optimal choice for optimal engine protection and performance.
