This diesel additive can be used to winterize and improve the quality of high sulfur, low sulfur and ultralow sulfur diesel fuels. It can also be used to winterize soy based biodiesel blends up to 5%. Typical applications include fleets, farms, power generation, and all other heavy-duty diesel applications.

Diesel Guard™ D-Thaw is specially formulated to be the most cost effective product to use in cold weather emergencies to get equipment running after it has been shut down due to iced or gelled fuel filters and lines. D-Thaw can be safely poured directly into the fuel filter to quickly melt ice and wax. The treated fuel filter can then be reconnected and the unit can be started. The balance of the quart should be added to the saddle tank to prevent further icing problems.
Carrying a couple bottles on board trucks will give immediate access to a corrective solutionin an emergency shutdown, eliminating the need to call for towing assistance and being stranded in the cold. It is better to be prepared for emergency situations than helpless on the side of the road. With continuous use, D-Thaw safely removes water and provides additional deicer for small storage tanks or truck saddle tanks. Use Diesel Guard™ Tank-Dri to remove larger amounts of water in fuel storage systems after the tank bottoms have been removed. This will help reduce down time, lower maintenance costs and provide better operation of equipment.
