Dealing With Diesel in a Petrol Car: Know What To Do

petrol car

Every car owner dreads making that one mistake at the fuel station – putting the wrong fuel type in their vehicle. One commonly experienced mix-up is using diesel in a petrol vehicle. Though petrol in a diesel car is a more frequent scenario owing to the size of the fuel nozzle, the reverse does occur, and this problem is not to be neglected.

A diesel-in-petrol mistake, though rarer, is potentially harmful to your vehicle. Unlike petrol, diesel needs to be compressed before it can ignite, and as petrol engines don’t work on this principle, it can lead to a variety of complications. Diesel is lubricious and heavier than petrol, and it does not evaporate as readily, causing issues in the combustion process of petrol engines and leading to possible engine damage over time.

So, what should you do if you’ve accidentally filled your petrol car with diesel fuel? The first thing to remember is not to ignite the engine. This could circulate the diesel throughout your system and exacerbate the situation. Once you realise your mistake, it’s crucial to contact a professional wrong fuel recovery service like Fuel Fixer. With a network of mobile units across the UK, we can reach your location promptly, usually within 46 minutes, bringing expertise and necessary tools to address your misfuel situation.

In the upcoming sections, we will detail the potential effects of using diesel in a petrol car and the steps professionals take to alleviate the situation. This guide will help you understand the best practices in such circumstances and reassure you that with expert help, a misfuelling mistake can be rectified effectively and efficiently.

The Impact of Diesel in a Petrol Engine

Before discussing the solution, it’s important to be aware of the potential damages that can occur due to using diesel in a petrol engine. While diesel in a petrol engine is not as damaging as petrol in a diesel engine, getting the wrong fuel out as soon as possible is crucial to avoid subsequent problems. It primarily impacts the three stages of the combustion process: ignition, combustion, and emission. Some effects include:

1. Lack of Ignition: Diesel does not vaporise easily and requires higher compression to ignite than petrol. As a result, the spark plugs in a petrol engine may fail to ignite the diesel, preventing the engine from running properly.

2. Incomplete Combustion: Due to its different compression requirements, diesel might not burn completely in a petrol engine. This can result in unburned fuel in the combustion chamber, leaving deposits and causing poor engine performance.

3. Contaminated Catalytic Converter: The unburned diesel can cause soot buildup in the exhaust system, damaging the catalytic converter and negatively affecting emissions.

4. Clogging of Injectors and Fuel Lines: Diesel is thicker and has higher lubricity than petrol. If left in the car’s fuel system for an extended period, it can cause clogging or residue buildup in the injectors and fuel lines, potentially leading to reduced fuel efficiency and engine performance.

Immediate Steps to Minimise Damage

As soon as you realise that you have filled your petrol car with diesel, make sure you follow these immediate steps to minimise potential damage:

1. Turn Off the Engine: Do not start or rev the car once you suspect misfuelling. Running the engine can allow the diesel fuel to circulate throughout the vehicle’s fuel system, worsening the situation.

2. Move Your Vehicle to a Safe Place: If possible, move your car to a safe and secure location without starting the engine. This will ensure you are in no immediate danger and can calmly proceed with the necessary actions.

3. Contact a Professional Wrong Fuel Recovery Service: Call Fuel Fixer for prompt assistance, as attempts to address the problem on your own could result in further damage or expensive repairs.

Rectifying the Error: Wrong Fuel Removal and Flushing

To resolve the issue of diesel in a petrol car, a professional wrong fuel removal process consisting of fuel draining and system flushing is essential. At Fuel Fixer, our expert technicians follow a systematic procedure to ensure your vehicle is back in optimal condition as swiftly as possible:

1. Draining the Tank: Using specialised equipment, our technician will first remove the diesel fuel from your vehicle’s tank. This is critical to remove the majority of the incorrect fuel and prevent it from causing further complications.

2. Flushing the System: After draining the tank, the whole fuel system must be flushed to rid the fuel lines, injectors, and filters of any remaining diesel. Our technician will use a high-quality fuel system cleaner to ensure the process is thorough and effective.

3. Refilling the Tank with Petrol: Following the flush, our technician will refill your car’s fuel tank with the correct petrol fuel to help the engine run smoothly once the problem is resolved.

4. Additional Checks: To confirm the effectiveness of the process and ensure your vehicle’s functionality, our technician will perform a series of tests, including engine diagnostics and assessing the exhaust emissions. This will ensure that your car is safe to drive and operating at its peak performance.

Adopting Preventative Measures

To avoid the risk of diesel-in-petrol misfuelling mistakes in the future, consider adopting the following preventative measures:

1. Label Your Fuel Cap: Many drivers misfuel due to a lack of awareness about their vehicle’s fuel requirements. By clearly labelling your fuel cap with the appropriate fuel type, you can minimise the risk of committing this error.

2. Be Attentive at the Pump: Always double-check the fuel pump handle and the label on the pump before adding fuel to your car. Misfuelling often occurs when drivers are tired, stressed, or distracted.
