Johnsens Iso Gas Antifreeze is suggested for use in fuel injected engines.  It combines the fuel system with isopropyl alcohol to form a mix and recuse the risk of the fuel freezing.  This product is used to prevent water in a vehicles fuel system from freezing.  By mixing with water, it lowers the freezing point of the mixture.  If this happens it can block the fuel lines and cause starting problems.  Johnsens Iso Gas Antifreeze should be used in cold weather which each fill up.
