Every year, thousands of drivers accidentally fill their diesel vehicles with petrol or vice versa, resulting in severe damage and costly repairs. It’s a mistake that can happen to anyone, but knowing the symptoms of wrong fuel in your car can help you take swift action. In this guide, we outline the critical signs that indicate you’ve put the wrong fuel in your vehicle and how to respond effectively.
Understanding the Severity of Misfuelling
Putting the wrong fuel in your car is not just a simple mishap; it can lead to significant engine damage if not addressed immediately. Whether you’re a first-time driver or an experienced motorist, it’s crucial to recognize the symptoms of wrong fuel as soon as they occur. Early detection can save you from costly repairs and even more severe complications down the line.
Immediate Symptoms of Misfuelling
The moment you start your engine after refuelling, the type of fuel in your tank begins interacting with your engine components. If you’ve put the wrong fuel in your car, here’s what you’ll likely notice right away:
- Difficulty Starting the Engine: One of the first signs is trouble starting the car. Petrol in a diesel engine acts as a solvent, reducing lubrication and causing friction between engine components. If you have mistakenly filled up with petrol, your diesel engine might struggle to turn over or may not start at all.
- Unusual Noises: A wrong fuel mix can cause unusual knocking or pinging sounds. These noises result from the engine misfiring due to incorrect combustion. If you hear any abnormal sounds, stop the car immediately.
- Poor Performance: You might notice a significant drop in power, sluggish acceleration, or an inability to reach higher speeds. Your vehicle may also stutter or jerk during operation. This is a clear sign that your engine is not receiving the proper fuel type for efficient combustion.
- Excessive Smoke: Another symptom is excessive or colored smoke from the exhaust. Diesel engines, when running on petrol, produce white or grey smoke, indicating incomplete combustion. This is a serious sign that requires immediate attention.
- Engine Warning Light: The engine management system in modern vehicles is designed to detect when something is wrong. If you’ve misfuelled, the engine warning light might illuminate. Never ignore this warning; instead, seek professional help immediately.
Long-Term Effects of Driving with the Wrong Fuel
If the wrong fuel remains in your tank for too long, the effects can be devastating. While some drivers might notice symptoms right away, others may not realize the mistake until significant damage has occurred. Here are some of the long-term issues caused by misfuelling:
- Engine Damage: Continuous operation with the wrong fuel can cause severe engine damage, particularly in diesel vehicles. Petrol lacks the lubrication properties of diesel, leading to increased wear and tear on components such as fuel injectors and the fuel pump.
- Clogged Fuel System: Misfuelling can lead to clogging within the fuel system, including filters, pumps, and injectors. Over time, this can result in complete system failure, requiring extensive repairs.
- Catalytic Converter Failure: The catalytic converter is essential for reducing harmful emissions. However, using the wrong fuel can damage this component, leading to increased pollution and a costly replacement.
What to Do If You Suspect Wrong Fuel in Your Car
If you suspect that you’ve filled your car with the wrong fuel, time is of the essence. Follow these steps to minimize damage and resolve the issue:
- Do Not Start the Engine: If you realize the mistake before starting the engine, do not attempt to start it. Starting the engine will circulate the wrong fuel throughout the system, leading to more significant damage.
- Call a Professional: Contact a fuel drainage service like Wrong Fuel Doctor. They specialize in removing contaminated fuel from your vehicle and ensuring no further damage occurs. Their swift and efficient service can save you thousands in repairs.
- Don’t Attempt to Fix It Yourself: Misfuelling is not a DIY job. The fuel system in modern cars is complex, and attempting to drain the fuel yourself can lead to further complications. Always rely on professionals for this task.
- Monitor Your Vehicle: After the wrong fuel is removed and the system is flushed, monitor your vehicle for any lingering symptoms. If you notice any, return to the service provider immediately for further inspection.
How to Avoid Misfuelling in the Future
Preventing misfuelling is all about being cautious and aware. Here are some tips to avoid making this costly mistake:
- Double-Check the Pump: Always double-check the fuel pump nozzle before filling up. Make sure it matches your vehicle’s fuel type.
- Label Your Fuel Cap: Consider labeling your fuel cap with the correct fuel type as a visual reminder.
- Stay Focused: Avoid distractions while refuelling. A lapse in concentration is all it takes to make a costly mistake.
