Schaeffer's Tank Dry is a moisture inhibiting fuel additive.
It is formulated for use in ALL types of diesel fuel, bio-diesel, gasoline and ethanol blends.
It is important to keep Fuel Storage Tanks free from water contamination. Water contamination is a significant problem for diesel fuel storage tanks. When water is allowed to penetrate a storage tank, it can quickly degrade diesel fuel and significantly lessen the performance of the vehicles that use the fuel.
