Gasoline was sold on a first-come, first-served basis, with fill-ups limited to five gallons per car. The fuel shortage began on 17 October 1973, when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC) decided to cease oil exports to nations that had supported Isreal during its conflict with Egypt and Syria, better known as the Yom Kippur War. The embargo caused a fuel shortages in the US, western Europe and Japan that lasted until march of 1974 and changed the car industry forever.
