In Nova Scotia, its price is the same as gasoline. The price is set by the industry rather than government agreement, and varies as the distance from Alberta. Although propane has lower BTU energy than gasoline, it has an octane rating of 104 without needing additives like gasoline. The octane rating of Esso regular gasoline is 87, Esso Supreme is 92. The rating of US gasoline is often as low as 82.
Propane is a clean burning fuel, producing water vapour and carbon dioxide as waste products.
It enters the engine as a gas, so it does not have to be vapourized like gasoline in a warm engine. Since there is no water content in the fuel, vapour lock in hot weather and high altitudes is not a problem or is fuel line freezing in winter. Propane even reduces emissions in vehicles without emission control devices. In British Columbia alone there are 1,100 propane refill stations compared to 1,700 gasoline refill stations. Existing refuelling stations are capable of handling three times the current volume of business.
