In fact, you must regularly use it to keep the petrol system in tip-top shape for when you need it.
Most modern dual-fuel systems actually use petrol when the engine is started. Some use a small amount of petrol to assist rapid and smooth starting.
Others start on petrol before automatically switching over to LPG after a set time, while others start on petrol and switch over the LPG once a number of set parameters, such as engine temperature, are met.
For that reason it's important that you don't to forget put some petrol in the petrol tank so you don't inadvertently run out and find yourself stranded with a car that won't start.
In other instances, such as with a high performance car, systems will automatically switch from LPG to petrol to ensure the fuel flow is sufficient for the engine's needs at high engines speeds when the LPG system can't keep up.
Because the engine still runs some of the time on petrol it is important to keep the fuel as fresh as possible to ensure smooth and troublefree starting and running.
It is also important to regularly run the engine on petrol to keep the fuel system components primed and in good working condition. Our LPG experts say you should run at least 20 litres of petrol through the system every month.
In same cases the petrol fuel pump, which is located in the petrol tank, runs even when the engine is running on LPG. To prevent the petrol pump from being damaged it is recommended that the petrol tank be at least a quarter full at all times.
