Why Diesel in Petrol Car Is a Problem

Petrol and diesel engines operate differently, and their fuels have distinct properties. Petrol engines rely on spark plugs to ignite the fuel-air mixture, while diesel engines use compression ignition. Diesel fuel is thicker and less volatile than petrol, which means it does not vaporize easily in a petrol engine.

When diesel enters a petrol engine, it can cause:

• Clogged fuel injectors due to diesel’s thicker consistency

• Poor combustion leading to misfires or engine stalling

• Damage to spark plugs and ignition components

• Potential damage to the fuel pump because diesel does not lubricate the same way petrol does

  
  

The severity of the damage depends on how much diesel was added and whether the engine was started after the mistake.

How to Recognize Diesel in Petrol Car

If you accidentally fill your petrol car with diesel in Cambridgeshire, you might notice some warning signs quickly:

• Difficulty starting the engine or failure to start

• Rough idling or engine misfires

• Smoke from the exhaust, often black or grey

• Loss of power while driving

• Warning lights on the dashboard, such as the check engine light

  
  

If you notice any of these symptoms right after refueling, stop driving immediately to prevent further damage.

Immediate Steps to Take After Realizing the Mistake

Do Not Start the Engine

If you realize the error before starting your car, do not turn the ignition. Starting the engine circulates the diesel through the fuel system, increasing the risk of damage.

Inform the Fuel Station Staff

Let the staff at the Cambridgeshire fuel station know about the mistake. They may be able to assist or advise on local services that can help.

• If you drive multiple vehicles, keep fuel cards or reminders in each car

• Ask the fuel station staff if you are unsure about the correct fuel type

  
  

What If You Started the Engine?

If you started the engine after putting diesel in petrol car, the diesel will have circulated through the fuel system. This can cause more extensive damage, including:
