Light Duty Fleet Experience with LP-Gas


The Automobile Club is conducting an extensive testing program to determine the suitability of LP-Gas as a substitute motor fuel to help reduce emission levels. In addition to the emissions characteristics of converted vehicles the Club is concerned with maintenance, driveability, safety, and costs. The following conclusions were reached: (1) Operations of motor vehicles using LP-Gas is practical in a fleet operation. (2) Emissions levels are significantly lower for vehicles operating on LP-Gas than they are for similar vehicles in similar service operating on gasoline. (3) Maintenance requirements for LP-Gas powered vehicles are lower than those of similar vehicles in similar service. (4) Available horsepower of LP-Gas powered vehicles is reduced slightly, but this does not affect the driveability significantly. (5) The conversion to LP-Gas is cost effective and will pay out well within the life expectancy of the vehicle. It is practical to move conversion kits from vehicles which are being retired to replacement units. (6) The fuel is safe and easy to handle.
