What Happens When You Put the Wrong Fuel in Your Vehicle


Before diving into costs, it’s important to understand what happens when the wrong fuel enters your vehicle’s system. Petrol and diesel engines operate differently, and their fuel systems are designed for specific fuel types.


  • Petrol in a diesel engine: Diesel engines rely on fuel to lubricate the fuel pump and injectors. Petrol lacks this lubricating property and can cause damage to these components. It may also cause the engine to misfire or fail to start.

  • Diesel in a petrol engine: Diesel is thicker and harder to ignite in a petrol engine. This can clog spark plugs and fuel injectors, leading to poor engine performance or failure to start.


The severity of damage depends on how much wrong fuel was added and whether the engine was started after fueling.


Immediate Steps to Take After Realizing the Mistake


Taking quick action can reduce repair costs significantly. Here’s what to do:


  • Do not start the engine. Starting the engine circulates the wrong fuel through the system, increasing damage.

  • Call us now (07900 379492). We can drain the fuel tank safely.


Breakdown of Costs to Fix Wrong Fuel Issues


The total cost to fix wrong fuel problems varies widely depending on the vehicle type, amount of wrong fuel, and damage extent. Below is a detailed breakdown of typical expenses.


1. Fuel Drain and Tank Cleaning


The first step is to drain the contaminated fuel and clean the fuel tank.


  • Cost range: £150 to £500

  • Details: This includes labor to drain the tank, dispose of the wrong fuel safely, and flush the fuel system. Some vehicles may require fuel filter replacement during this process.


2. Diagnostic Fees


Our technicians can perform diagnostics to assess damage.


  • Cost range: £50 to £100

  • Details: This fee is often included in repair costs but can be separate depending on the vehicle.


Factors Influencing Repair Costs


Several factors affect how much you will pay to fix wrong fuel problems:


  • Vehicle type: Luxury or diesel vehicles tend to have higher repair costs.

  • Amount of wrong fuel: A small amount may only require draining and filter replacement.

  • Whether the engine was started: Starting the engine spreads the wrong fuel and increases damage and cost.

  • Location and labor rates: Repair costs vary by region.


Examples of Repair Costs in Real Situations


  • A petrol car with a few liters of diesel mistakenly added, caught before starting, may only cost around £150 to drain.

  • A luxury petrol car that started with diesel may cost around £400 to drain.


Preventing Wrong Fuel Mistakes


Avoiding the problem is the best way to save money. Here are some tips:


  • Double-check fuel type before filling. Look for labels on the pump and your vehicle.

  • Use fuel caps with clear markings. Some vehicles have different caps for petrol and diesel.

  • Ask for help if unsure. Station attendants can assist if you’re uncertain.

  • Keep calm and don’t rush. Mistakes often happen when in a hurry.


What to Expect During the Repair Process


  • We will drain the fuel tank completely.

  • The fuel system will be flushed and cleaned.

  • The mechanic will test the engine to ensure proper function.


Final Thoughts on Fixing Wrong Fuel Issues


Fixing wrong fuel problems can be expensive, especially if the engine was started. Acting quickly by not starting the car and calling our professionals can save hundreds or thousands of pounds. Knowing the potential costs helps you prepare and make informed decisions if this mistake happens.


If you ever find yourself in this situation, focus on safety, avoid driving the vehicle, and seek professional help immediately. Prevention is key, so always double-check your fuel type before filling up.
