Putting the wrong fuel in your car is a surprisingly common mistake, but it can have serious consequences for your vehicle. Acting quickly is essential to prevent lasting damage. If you realise your error before starting the engine, do not turn on the ignition and call for professional help. A mechanic or fuel specialist can drain the tank and flush the system with the correct fuel. If you have used a small amount of the wrong fuel, you may be able to dilute it by filling the rest of the tank with the correct fuel. However, if you have used a significant amount, you may need to replace the entire engine, which can be very expensive.

What You'll Learn
Don't start the ignition
Putting the wrong fuel in your car is a surprisingly common mistake. It's important to act quickly and not to start the ignition if you realise your error before turning on the engine. This is because the wrong fuel cannot be processed by the engine and will cause it to run incorrectly, leading to performance issues such as unusual engine noises, reduced performance, stalling, and excessive smoke.
If you have put petrol in a diesel car, the mixture will act as a solvent, dissolving the lubricant that diesel provides and increasing friction between components. This can cause serious damage to parts such as your fuel lines, fuel injectors, pistons, and fuel pump. If you have put diesel in a petrol car, the diesel will coat spark plugs and the fuel system, causing misfiring and incomplete combustion, which can lead to higher levels of carbon monoxide emissions.
To prevent further damage, you should leave your engine switched off and avoid putting your key in the ignition. If the engine is already running, turn it off immediately if it is safe to do so. If not, pull over to a safe spot. Then, inform the staff at the petrol station of your mistake.
From here, you have a few options. If you have only used a small amount of the wrong fuel, you can fill the rest of the tank with the correct fuel to dilute the contaminated fuel and prevent significant harm. However, if you have used a significant amount of the wrong fuel, it is best to seek professional help. A mechanic or fuel recovery specialist can drain the fuel tank and flush the fuel system with the correct fuel to prevent further damage. This process can take anywhere from a few minutes to a few hours, depending on the amount of wrong fuel in the tank and the tank's accessibility.

Call for help
If you've put the wrong fuel in your car, it's important to act quickly to prevent any damage to your engine. The first thing to do is to not start the engine and to call for help. Depending on where you are, waiting times can vary, but you can expect a recovery specialist to arrive within an hour.
Call a breakdown assistance provider and explain that you've misfuelled your car. If you have breakdown cover, call them and they will be able to send a recovery specialist. If you don't have breakdown cover, you can contact a local mobile mechanic or a specialist company that deals with fuel removal. Companies such as Fuel Fixer provide a 24/7 rapid response wrong fuel drain recovery service and can have someone out to you quickly.
If you have used a small amount of the wrong fuel, filling the rest of the tank with the correct fuel may dilute the contaminated fuel enough to prevent any significant harm. However, if you have used a significant amount of the wrong fuel, it is best to seek professional help. A mechanic or a fuel removal specialist will be able to advise you on the best course of action, which may include draining the fuel tank and flushing the fuel system.
The cost of repairs can be significant, and in some cases, the engine may need to be replaced entirely. It is therefore important to act quickly and seek professional help to minimise the risk of damage to your vehicle.

Drain the tank
If you've put the wrong fuel in your car, it's important to act quickly to prevent damage to your vehicle. The first step is to refrain from starting the engine and avoid turning on the ignition. This is because the wrong fuel can cause internal damage to the engine and other parts of the car, such as the fuel system and the catalytic converter.
If you have only used a small amount of the wrong fuel, one option is to fill the rest of the tank with the correct fuel. This may dilute the contaminated fuel enough to prevent any significant harm. However, if you have used a significant amount of the wrong fuel, it is best to seek professional help.
Draining the tank is a crucial step in rectifying the issue of putting the wrong fuel in your car. Here is a step-by-step guide on how to drain the tank:
- Contact a professional mechanic or a fuel removal specialist. They have the necessary tools and expertise to safely and effectively drain the tank.
- The specialist will locate the fuel tank in your car. The tank's location varies depending on the vehicle's make and model.
- They will then proceed to extract the contaminated fuel from the tank. This process can take anywhere from a few minutes to a few hours, depending on the amount of wrong fuel in the tank and the tank's accessibility.
- After draining the wrong fuel, the mechanic or specialist will flush the fuel system with the correct fuel to ensure that any remaining contaminants are removed.
- They may also inspect the engine and other components for any damage caused by the wrong fuel. This includes checking the fuel lines, fuel pump, spark plugs, and pistons for any signs of increased friction or wear and tear.
- If necessary, the specialist will recommend and perform repairs or replacements to ensure the proper functioning of your vehicle.
Remember, it is important to act promptly and seek professional assistance when dealing with wrong fuel in your car. While it may be tempting to try quick fixes, they can often lead to more severe and costly issues down the line.

Flush the system
If you've put the wrong fuel in your car, it's important to act quickly to prevent lasting damage to your vehicle. The first step is to refrain from starting your engine, as this can circulate the incorrect fuel mixture and increase friction between components, causing damage to parts such as your fuel lines and pump.
If you have only used a small amount of the wrong fuel, you may be able to dilute the contaminated fuel by filling the rest of the tank with the correct fuel type. However, if you have used a significant amount of the wrong fuel, it is best to seek professional help.
A professional mechanic or fuel removal specialist will be able to drain the fuel tank and perform a system flush to prevent further damage. This process involves removing the contaminated fuel and flushing the system with the correct fuel. The cost and time required for this process will depend on the amount of incorrect fuel in the tank and the accessibility of the tank.
After the fuel system has been flushed, it is important to have your car thoroughly inspected for any damage. In some cases, additional repairs or replacements of damaged components, such as fuel pumps or injectors, may be necessary.
To summarise, putting the wrong fuel in your car can be a costly mistake, but taking immediate action and seeking professional help can help minimise the damage and restore your vehicle's functionality.
