This is for a case of 24 16oz bottles of D-Gel emergency fuel additive. D-GEL is an emergency diesel fuel additive treatment that reliquefies iced and gelled diesel fuel and heating oil. Diesel fuel can become frozen when water in the fuel freezes or gelled when wax crystals thicken and coagulate. In either case, fuel flow is reduced or eliminated entirely resulting in reduced engine power or total engine shutdown. D-GEL will reliquefy diesel fuel in either of these two conditions. D-GEL is completely safe for treating emergency diesel fuel and heating oil problems encountered in severe winter weather.
