Accidentally putting diesel in your petrol car can feel like a nightmare. But don’t worry — it’s a common mistake, and it’s fixable if you act fast. Whether you’ve just filled the wrong fuel or realized it moments later, follow this step-by-step guide to resolve the issue efficiently and avoid potential damage to your car.
Signs You’ve Put Diesel in Your Petrol Car
It’s essential to identify if you’ve mistakenly fueled with diesel. The symptoms of diesel in your petrol car are often immediate:
- Engine misfire or sputtering: One of the first signs that something is wrong.
- Difficult engine start or no start: The car may struggle to turn over due to the incompatible fuel.
- Excessive smoke from the exhaust: Diesel is much thicker than petrol, leading to excess smoke as it burns incorrectly.
- Loss of power: You might experience a drastic reduction in engine power.
What Happens When You Put Diesel in a Petrol Car?
The damage can vary depending on how much diesel you've added and how long the engine has been running with the wrong fuel. Since petrol engines rely on a spark to ignite the fuel, diesel's lower combustibility causes engine inefficiencies.
Diesel can clog petrol engines, leading to expensive repairs. Unlike petrol, diesel does not evaporate easily and can leave oily residues in the fuel injectors and filters. Therefore, it's critical to act swiftly to prevent long-term damage.
Steps to Take Immediately
Turn off the engine: As soon as you realize you’ve put diesel in your petrol car, switch off the engine to prevent it from circulating further into the system.
Don’t try to start the car: Running the engine will only make matters worse by spreading the diesel through the fuel lines, filter, and injectors.
Push your car to a safe spot: If you’re at a gas station, push your car to a parking area to avoid obstructing the pumps.
Contact a fuel removal service: Look for a Wrong Fuel Rescue services provider near me to get expert help as soon as possible. They will drain the contaminated fuel and clean the system.
How Diesel is Removed from Your Petrol Car
Once you've contacted professionals, here’s what typically happens:
- Fuel Draining: Experts will use special tools to safely drain all the diesel from your petrol tank and fuel lines.
- Fuel System Cleaning: After draining, they’ll clean the fuel lines, injectors, and filters to ensure no residual diesel remains.
- Fuel Refill: Once everything is clean, fresh petrol is added to get the car back to normal functioning.
In most cases, this process will get your car running again without any significant damage, as long as the engine was not started or driven extensively with the wrong fuel.
Why You Should Not Attempt DIY Fuel Draining
It might be tempting to fix the issue yourself, but draining the fuel tank without the right tools and expertise can be dangerous. Mishandling fuel, especially if it involves diesel, can lead to spills, fires, or further contamination of your car's internal systems. Leave this task to professionals who are trained and equipped to handle it safely.
Preventive Measures for the Future
To avoid future mishaps, consider the following:
- Label your fuel cap: Placing a label indicating "PETROL ONLY" on your fuel cap is a simple reminder.
- Double-check at the pump: Always double-check the pump nozzle and your vehicle’s fuel type before refueling.
- Use fuel cap locks: Some cars come with fuel cap locks that only open with the correct key, preventing you from filling with the wrong fuel.
Potential Long-term Damage
While addressing diesel in a petrol car quickly often avoids long-term issues, prolonged driving with the wrong fuel can lead to:
- Clogged fuel injectors: Diesel is thicker than petrol, which can block fuel injectors over time.
- Damaged catalytic converter: Diesel does not burn as cleanly as petrol, which can harm the catalytic converter.
- Fuel system damage: Extended exposure to diesel can cause significant damage to your car's fuel lines and filters.
What to Do If You’ve Already Driven the Car
If you’ve already driven after mistakenly putting diesel in your petrol car, the situation becomes more urgent:
- Stop immediately: Pull over as soon as you realize the mistake. Running the engine for even a few kilometers can cause extensive damage.
- Call a professional service: Reach out to a Wrong Fuel Rescue services provider near me or a roadside assistance service to help drain and clean your fuel system.
Cost of Fixing the Issue
The cost of repairing a petrol car that’s been fueled with diesel will depend on the extent of damage and whether or not the car was driven after the mistake. Typically, draining the wrong fuel and cleaning the system can cost anywhere from $200 to $500. However, if the fuel injectors, filters, or catalytic converter are damaged, costs could climb much higher.
Conclusion
Filling your petrol car with diesel can be a stressful experience, but with quick action and the help of professionals, you can fix the issue without long-term damage. Be sure to follow the preventive steps to avoid making the same mistake again.
