What to Do If You Put the Wrong Fuel in Your Car

Accidentally filling your car with the wrong type of fuel is a common mistake that can happen to anyone. Whether you're in a rush or simply distracted, it's easy to grab the wrong pump. But don't worry, knowing what steps to take can help minimize any potential damage to your vehicle. In this article, we'll guide you through what to do if you find yourself in this situation.

Understanding Fuel Types

Before diving into the steps to take, it's important to understand the different types of fuel. The most common types are petrol (also known as gasoline) and diesel. Petrol is typically used in cars with spark-ignition engines, while diesel is used in compression-ignition engines. Using the wrong fuel can cause significant damage because these engines operate differently.

Another term you might hear is 'octane rating,' which refers to the fuel's ability to resist knocking or pinging during combustion. Higher octane fuels are often used in high-performance vehicles. Diesel, on the other hand, is measured by its cetane number, which indicates how quickly the fuel ignites under pressure.

Immediate Steps to Take

If you realize you've put the wrong fuel in your car, the first thing to do is not to start the engine. Starting the engine can circulate the incorrect fuel through the system, increasing the risk of damage. Here's what you should do instead:

Stay Calm: Panicking won't help. Take a deep breath and focus on the next steps.
Do Not Start the Car: If you haven't started the car yet, don't. This will prevent the wrong fuel from circulating.
Move to a Safe Location: If you're at a busy fuel station, push the car to a safe spot if possible.
Call for Help: Contact a professional fuel drain service. They have the tools and expertise to safely remove the incorrect fuel.

What Happens If You Start the Engine?

If you've already started the engine, turn it off as soon as possible. The longer the wrong fuel circulates, the more damage it can cause. Petrol in a diesel engine can strip away lubrication, leading to increased wear and tear. Diesel in a petrol engine can cause knocking and damage to the fuel injectors.

In this case, you'll still need to call a professional service to drain the fuel. They may also need to flush the fuel system and replace the fuel filter.

Preventing Future Mistakes

To avoid making the same mistake again, consider these tips:

Label Your Fuel Cap: Use a sticker or label to remind yourself of the correct fuel type.
Double-Check Before Filling: Take a moment to verify the pump and fuel type before you start filling.
Stay Focused: Avoid distractions while at the pump. Focus on the task at hand.

Conclusion

Putting the wrong fuel in your car can be a stressful experience, but knowing the right steps to take can help mitigate the damage. Remember, the key is to stay calm and avoid starting the engine. Contact a professional to handle the situation safely. Think about what features matter most to you. Do you need extra cargo space? Or perhaps fuel efficiency is your top priority? Whatever your needs, being informed will help you make the best decision for your next car purchase.
