What Happens If You Put the Wrong Fuel into a Car?
July 29, 2024
Putting the wrong fuel into your car can be a distressing and costly mistake. Whether it’s accidentally pumping petrol into a diesel vehicle or vice versa, the consequences can range from minor inconveniences to severe engine damage. In this blog post, we will explore the effects of misfuelling, how quickly you can realise the mistake, what happens when you put petrol in a diesel car and drive it, and what steps to take if you find yourself in this predicament.
How quickly would you know if you put the wrong fuel in your car?
Misfuelling can happen in an instant, often due to distractions or confusing fuel pump labelling. The moment you realise your mistake may vary. However, some immediate signs can alert you to the error. These include difficulty starting the engine, rough running, strange noises, or dashboard warning lights. The sooner you recognize the problem, the better chance you have of minimizing the damage.
What happens if you put petrol in a diesel car and drive it?
When petrol is introduced into a diesel car’s fuel system, it can have detrimental effects. Diesel engines rely on compression ignition, while petrol engines use spark ignition. Petrol acts as a solvent, reducing lubrication and causing premature wear and tear on diesel engine components. The fuel pump, injectors, and other critical parts may suffer damage. The misfuelled car may experience power loss, misfires, stalling, and even complete engine failure.
What should I do if I accidentally put diesel in my car?
If you accidentally put diesel into a petrol car, the consequences are generally less severe, but it still requires immediate attention. Here are the steps to take:
1. Do not start the engine: Starting the engine can circulate the diesel fuel further, increasing the chances of damage.
2. Contact a professional: Call a breakdown service or a local mechanic for guidance. They can provide advice tailored to your specific situation and help you avoid potential complications.
3. Have the fuel system drained: To minimize damage, it’s crucial to have the contaminated fuel drained from the system as soon as possible. A professional mechanic will flush the system and replace the fuel with the correct type.
4. Check for additional issues: Depending on the extent of the misfuelling, there may be further damage to address. The mechanic will inspect the fuel system and engine components to ensure everything is functioning properly.
Putting the wrong fuel into a car can have serious consequences, ranging from engine damage to costly repairs. It’s essential to be vigilant and take immediate action if you find yourself in such a situation. Remember, consult a professional mechanic or your car’s manufacturer for expert advice tailored to your specific vehicle.
