After a Propane system has been installed, can I still run my car on gasoline?If a LPG system is installed, you can still run the vehicle on gasoline. The driver can decide which type of fuel to use by simply pressing the changeover switch located on the vehicles dashboard. The simplicity of using a gas system is also guaranteed by the fact that, with modern systems, the vehicle always starts on gasoline and automatically switches over to propane after about 30 seconds. This is after optimum operation parameters have been reached. The vehicles fuel distance is practically double when a gas system has been installed as it can count on its dual fuel supply.
