What Happens When a Gas-Converted Car Switches Back to Petrol?

The ignition system suffers the most damage, with the spark plugs being the most affected. Here are the detailed impacts: Reduced power and ignition capability: Since spark plugs are used for ignition, their deterioration leads to decreased power. The timing of ignition is precise, and missing the optimal ignition time results in reduced power. Incomplete combustion, increased fuel consumption: This affects the car's fuel efficiency. Insufficient ignition energy and incorrect ignition timing cause incomplete combustion, inevitably leading to higher petrol consumption. Carbon buildup, engine damage: Due to inadequate ignition performance causing incomplete combustion, significant carbon deposits accumulate on the piston tops and spark plug electrodes.
As an owner with several experiences of switching back from natural gas to gasoline, I'd like to share my story. My old Bora had an LPG system installed and ran on it for over two years. Later, as many nearby gas stations closed, I decided to switch back to gasoline. I went to a professional repair shop to remove the gas tank and nozzle system, which took half a day. After the conversion, I immediately noticed the engine started faster, especially during cold starts, which were much more stable. The throttle response became more direct, and the power output during acceleration was clearer. However, fuel consumption did increase by about 15%, and now I spend around 200 yuan more on gas each month. A reminder to everyone: after removing the gas system, carefully check the fuel line seals, as old connections might leak and affect the air-fuel mixture. I also took the opportunity to do an engine decarbonization cleaning, since natural gas combustion tends to leave carbon deposits. Overall, the driving experience improved, but my wallet got a bit lighter. I recommend weighing convenience and cost before making a decision. Regular maintenance is key—don't slack off.
