Liquefied Petroleum Gas (LPG)

An alternative fuel that may be used on its own, or in conjunction with petrol in bi-fuel cars. The LPG is housed in a separate tank and the driver can switch between the two sets of injectors (one for LPG, one for gasoline) using a dash-mounted switch. Although LPG does not offer as good a fuel economy as gas or diesel, it is much cheaper and pollutes less.
