Why Putting Petrol in a Diesel Car Is a Serious Problem


Diesel engines and petrol engines operate differently. Diesel fuel lubricates the engine’s fuel system, while petrol acts as a solvent and can damage diesel engine components. When petrol enters a diesel engine, it can cause:


  • Damage to fuel injectors and fuel pump due to lack of lubrication

  • Engine misfires or failure to start

  • Potential long-term engine damage if the car is driven with the wrong fuel


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



Immediate Steps to Take After Filling Petrol in a Diesel Car


1. Do Not Start the Engine


If you realize the mistake before starting the engine, do not turn the ignition. Starting the engine circulates the petrol through the fuel system, increasing the risk of damage.


2. Inform Everyone Around You


If you’re at a petrol station, alert the staff immediately. They may have protocols or tools to help, such as a fuel extraction pump.


3. Call a Specialist Rescue Service


Contact a professional like Wrong Fuel In Car Rescue Suffolk at 07904 731886. They have the equipment and expertise to safely drain the wrong fuel and prevent damage.


4. Arrange for Fuel Drainage


The wrong fuel needs to be removed from the tank and fuel lines. This usually requires:


  • Draining the fuel tank completely

  • Flushing the fuel system to remove petrol residues

  • Refilling with the correct diesel fuel


Attempting this yourself without proper tools can cause spills or further damage.



What Happens If You Start the Engine?


If you started the engine after filling petrol in a diesel car, the petrol will circulate through the fuel system. This can cause:


  • Immediate engine knocking or stalling

  • Fuel pump damage due to petrol’s lack of lubrication

  • Clogged fuel filters and injectors


In this case, stop driving immediately and call a professional. Continuing to drive can lead to costly repairs or even engine replacement.



How Professionals Fix Wrong Fuel Issues


Specialist rescue services follow a clear process to fix the problem:


  • Vehicle assessment to check how much petrol was added and if the engine was started

  • Fuel extraction using pumps or siphons to remove contaminated fuel

  • System flush to clean fuel lines, filters, and injectors

  • Refill with diesel and test the engine to ensure proper operation


They may also inspect for any damage caused and advise on repairs if needed.



Preventing Wrong Fuel Mistakes in Suffolk


Avoiding this problem is better than fixing it. Here are some tips to prevent filling petrol in a diesel car:


  • Check your car’s fuel type before refueling — look for labels on the fuel cap or inside the fuel door

  • Use fuel stations you trust and are familiar with

  • Pay attention to the pump nozzle size — diesel nozzles are usually larger and won’t fit in petrol cars easily, but petrol nozzles fit diesel cars

  • Ask for help if unsure — station attendants can assist if you’re uncertain which fuel to use



What to Expect in Terms of Cost and Time


The cost of fixing wrong fuel depends on:


  • How much petrol was added

  • Whether the engine was started

  • The extent of damage caused


Fuel drainage and flushing typically cost a few hundred pounds, but repairs for damaged components can increase the price. Time-wise, the process can take a few hours to a day depending on the severity.
