Q: What's Dry Gas?

asked by on November 24, 2015

What's dry gas?

Dry gas, or Drygas, is an alcohol based fuel additive. Its purpose is to remove excess water from gasoline by absorbing the water and burning it off in the combustion chamber. It also prevents water in gasoline from freezing by acting as an antifreeze. The presence of water in gasoline is considered a contaminant that can cause corrosion, freezing, and decreased combustive power. This contaminant has the potential to cause considerable damage to the fuel tank, fuel lines, and other engine components. Water contaminated gasoline can cause rust and corrosion in the components of the fuel delivery system. Corrosion is capable of creating holes in the fuel tank and weaken the fuel lines and metal fittings. Gas leaks have been known to happen as a result of corrosion. It is also possible for debris to clog fuel injectors as a result of water in gasoline. Excessive amounts of water in gasoline has the potential to freeze up fuel lines and is most common in areas where temperatures reach freezing levels or below. This may cause an engine hesitation or no start problem if water freezes and gasoline isn’t able to flow through the engine. When the presence of water in gasoline is considerably high, the fuel does not burn well and combustive power is reduced. This may cause a stalling condition if water contaminated gasoline sits in the combustion chamber.
