What Happens if You Put Petrol Into a Diesel Car
Putting petrol into a diesel car can have serious consequences for both your vehicle and your wallet. In the United Kingdom, where diesel cars are quite popular, it is not uncommon for people to mistakenly fill up with the wrong fuel. So, what exactly happens if you put petrol into a diesel car?
When petrol is introduced into a diesel engine, several issues arise. Petrol acts as a solvent, reducing lubrication in the fuel system. This can result in damage to the fuel pump and the injectors, which are vital components of a diesel engine. Additionally, petrol has a lower flashpoint than diesel, which means it ignites at a lower temperature. This can cause knocking and pinging in the engine, leading to damage to the cylinder walls and piston rings.
Moreover, diesel acts as a lubricant for the fuel system, and when petrol is added, it reduces this lubrication. This can lead to increased friction between metal parts, resulting in excessive wear and tear. The fuel system may also become clogged due to the different properties of petrol, which can cause a drop in engine performance and efficiency.
If you realize you have mistakenly filled your diesel car with petrol, it is crucial to avoid starting the engine. Starting the engine will circulate the petrol throughout the fuel system, making the damage worse. Instead, call for professional help or a breakdown service to drain and flush the fuel system.
