Q: Is Frostline only for diesel fuel?
A: Frostline is designed for use in heating oils and diesel fuels. It is not rated for use in gasoline, kerosene or other fuel types (most of these fuels do not require an anti-gelling additive).

Q: Does frostline get thick when it gets cold?
A: In extreme cold Frostline can get thicken or even appear to freeze, however, with a quick shake it is instantly a liquid again. Once in the fuel Frostline reacts with the diesel fuel and prevents it from gelling or freezing by not allowing the particles to coagulate together.
