How Does LPG Work?

An LPG Conversion works in exactly the same way as a normal petrol engine, just with a different fuel. Everything about your vehicle remains the same but a separate fuelling system is added with its own tank, piping, ECU and injectors.

Converted vehicles become “dual-fuel” - they can change between running on petrol or gas at the flick of a switch, even whilst driving. As LPG is a much cleaner fuel, there is less wear and tear on the engine and its life will be prolonged. LPG is also 100% lead-free, produces fewer emissions (which is why it attracts a lower duty rate) and causes less oil-contamination. Combustion is cleaner, your engine will be quieter and smoother and much better for the environment.

Earlier LPG systems are renowned for having problems when fitted to modern engines with all of their electronic wizardry. The car would detect that something wasn’t quite right and try and adjust the fuel flow, resulting in backfires, stuttering and occasionally more serious problems.

Thankfully, modern systems are now able to completely interact with most makes of vehicle and you won’t know whether you are running on petrol or gas without looking at the switch.

Also, LPG-converted cars are now starting to rise in residual value as buyers realise that they can run at half the costs of a normal car.
