USERS of internal-combustion engines have long recognized the need for a fuel which possesses high-octane rating, resistance to detonation, and ideal combustion characteristics; a fuel which would minimize engine maintenance costs, and which would be plentiful enough to assure long-range price stability. This paper cites propane, a common liquefied petroleum gas, as possessing all these and many more advantages.
The author points out the safety factors in the sealed fuel system, the lessening of noise resulting from smooth performance, and the elimination of exhaust smoke and odors from a fuel which burns carbon-free and smokeless.
Comparative charts are provided covering fuel costs, storage costs, and fleet operating expenses.
