Why Putting Petrol in a Diesel Car Is a Serious Problem


Diesel engines and petrol engines work differently. Diesel fuel lubricates the engine’s fuel system, while petrol acts as a solvent and can damage parts designed for diesel. When petrol enters a diesel tank, it reduces lubrication and can cause:


  • Damage to fuel injectors and fuel pump

  • Engine knocking or misfiring

  • Loss of power and poor engine performance

  • Potential engine failure if the car is driven


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


How to Recognize You’ve Put Petrol in a Diesel Car


Sometimes the error is obvious, but other times it may not be noticed until symptoms appear. Signs include:


  • Engine warning lights turning on

  • Rough idling or stalling

  • Difficulty starting the engine

  • Strange noises such as knocking or pinging

  • Sudden loss of power while driving


If you suspect wrong fuel, stop driving immediately to prevent further damage.


Immediate Steps to Take After Putting Petrol in a Diesel Car


If you realize the mistake before starting the engine:


  1. Do not start the car. Starting circulates the petrol through the system, increasing damage.

  2. Call for professional help. Contact a specialist like Wrong Fuel In Car Rescue Suffolk at 07904 731886 for expert assistance.

  3. Inform the rescue team about the fuel mix. This helps them prepare the right tools and plan the job efficiently.


If you started the engine and then noticed the problem:


  1. Stop driving as soon as it is safe.

  2. Turn off the engine to avoid further damage.

  3. Call a rescue service immediately.


What Professionals Do to Fix the Problem


Wrong Fuel In Car Rescue Suffolk and similar services follow a careful process to fix petrol in a diesel car:


  • Drain the fuel tank completely. Removing all contaminated fuel is essential.

  • Flush the fuel system. This clears petrol residues from fuel lines, injectors, and the pump.

  • Replace fuel filters. Petrol can clog or damage filters designed for diesel.

  • Check for damage. Inspect fuel injectors and the fuel pump for wear or failure.

  • Refill with the correct diesel fuel.

  • Test the engine. Ensure it runs smoothly before releasing the vehicle.


This process requires special equipment and expertise, so DIY attempts are not recommended.


How Much Does It Cost to Fix Petrol in a Diesel Car?


Costs vary depending on the amount of petrol added and whether the engine was started. Typical expenses include:


  • Fuel draining and flushing: £100 to £300

  • Replacement fuel filters: £50 to £150

  • Repairs to fuel pump or injectors if damaged: £300 to £1,000 or more


Getting professional rescue quickly can reduce the risk of costly repairs.


Preventing Petrol Mistakes in the Future


Avoiding this problem is better than fixing it. Here are some tips:


  • Always check the fuel type before filling up.

  • Look for clear labels on the fuel cap.

  • Use petrol pumps with different nozzle sizes to reduce confusion.

  • If you drive multiple vehicles, keep a note of which uses diesel.

  • Ask the station attendant for help if unsure.
