The performance, efficiency and range of a propane-fuelled vehicle is comparable to that of a gas-powered vehicle. Power or speed isn’t affected. When you start a propane-fuelled vehicle, it runs on petrol. When the pressure and temperature of certain components reach a certain level, the engine automatically begins burning propane instead of gas. The driver can switch from one mode to the other at the flick of a switch. Though it is easy to refuel at service stations across Quebec or at a propane gas distributor, managers of large vehicle fleets have opted for their own on-site installations. It should be noted that staff in such on-site installations have undergone training recognized by the appropriate authorities.
