Drip gas is a naturally occurring form of gasoline found near many oil and natural gas wells. It is a light gasoline-like hydrocarbon liquid that sometimes occurs with natural gas and collects in low spots in natural gas pipelines, where it can be drained out. In the 1930s, it was used by rural landowners in their automobiles. However, using drip gas in vehicles is illegal and has been reported to cause damage to engines. Drip gas is also known as oilwell condensate, white gas, casin head, and gas liquids.
