What If You Mistakenly Fill Your Car with the Wrong Fuel?

Whether you put petrol in a diesel automobile or the other way around, panicking is never a good idea.

Filling your car with the wrong fuel can be frustrating and costly, but it’s important not to panic. Knowing what to do in this situation can help you reduce the damage and get back on the road quickly. Here are tips on what to do if you mistakenly fill your car with the wrong fuel:

  • Don’t start the engine: The engine can cause serious damage to your car, as the wrong fuel can damage the fuel pump, injectors, and other engine components. If you’ve already started the engine, it’s best to turn it off immediately. 
  • Don’t try to siphon the fuel: Siphoning petrol out of the tank might be risky and ineffective. The fuel can combine with the current fuel, which could further harm your car.
  • Call for help: Contact a professional 24/7 fuel draining as soon as possible to help you. A professional can drain the fuel tank and flush the system with the correct fuel.
  • Take preventive measures: To prevent this situation in the future, always double-check to ensure you’re putting the right fuel in your car. If you’re unsure, you can check the owner’s manual or the label on the fuel pump. 

Filling your car with the wrong fuel can be costly, but if you know what to do, you can reduce the damage and get back on the road quickly. By following these tips, you can ensure your car runs smoothly and safely.

Which Type of Misfuelling Is the Worst?

The most frequent and dangerous misfuelling is using petrol in a diesel vehicle.

Fuel is used as lubrication in diesel engines; however, because petrol is corrosive, it can badly harm your machine and your car’s fuel pump.

If starting your car is difficult, you might have mistakenly poured petrol into a diesel tank. A louder-than-usual engine decreased power, and a smokey exhaust is some more warning signs.

As diesel nozzles are more significant than the filler neck on most petrol cars, it happens far less frequently when diesel is inadvertently put in a petrol vehicle.

Diesel clogs the system; thus, a petrol engine misfuelling is less likely to be catastrophic, but it still needs to be fixed right immediately. 

As you’re driving, exhaust smoke and a misfiring engine that may also have difficulties starting are telltale symptoms of accidentally putting diesel fuel in your petrol vehicle.

Draining and flushing the system (cleaning all polluted components and removing debris) should address the issue without more severe harm.

Nonetheless, given how flammable fuel is, it is advised that professionals handle this kind of activity with the proper safety gear.


Understanding the effects of using the incorrect fuel in your vehicle and what to do in the event of an error is crucial. Calling the wrong fuel service is the wisest action if you find yourself in this predicament. These businesses employ qualified personnel who can safely remove the incorrect fuel from your car and refill it with the correct fuel. The safest and most effective approach to restarting your car is to do it this way. Knowing what to do in the event of a wrong petrol mistake can be crucial to prevent more harm to your car and your finances.
