Accidentally Put Diesel in Petrol Car in Cambridgeshire

Petrol engines and diesel engines operate differently, so using the wrong fuel disrupts the engine’s function. Petrol engines rely on spark ignition, while diesel engines use compression ignition. Diesel fuel is thicker and less volatile than petrol, so when diesel enters a petrol engine:

• The fuel does not vaporize properly.

• The spark plugs may foul or fail to ignite the fuel.

• The fuel injectors and fuel pump can become clogged or damaged.

• The engine may stall, misfire, or fail to start.

  
  

If you start the car and drive even a short distance, diesel can circulate through the fuel system, increasing the risk of damage.

Immediate Steps to Take After Misfuelling

If you realize you have put diesel in a petrol car, act quickly to minimize damage:

1. Do not start the engine. Starting the car will push diesel through the fuel system and cause more harm.

2. Turn off the ignition if the engine is running.

3. Call a professional. In Cambridgeshire, the Misfuelled Car Fixer service at 0330 122 6640 offers expert help to safely remove diesel from your petrol car.

4. Do not attempt to drive the vehicle to a garage or fuel station.
