Putting diesel fuel in a petrol car is a mistake that can cause serious damage to the vehicle's engine and fuel system. While it may seem like a small mistake, the consequences can be significant and expensive. In this blog post, we will explore what happens if you put diesel in a petrol car and what you should do if it happens to you.
The Effects of Diesel Fuel on a Petrol Engine
Diesel fuel is not meant for petrol engines, and introducing diesel fuel into a petrol engine can have severe consequences. The first effect is that diesel fuel will not burn properly in a petrol engine. Diesel fuel is thicker and heavier than petrol, which means that it does not evaporate as quickly. As a result, diesel fuel can clog the fuel system and prevent the engine from running properly. Additionally, diesel fuel can cause damage to the spark plugs and other components of the engine.
Signs That You Have Put Diesel in a Petrol Car
There are several signs that you have put diesel in a petrol car. The first and most obvious sign is that the engine will not start. Diesel fuel is not as volatile as petrol, so it will not ignite when the spark plugs fire. As a result, the engine will fail to start. If you do manage to start the engine, it will run roughly and emit black smoke from the exhaust.
The engine will struggle to run on diesel fuel, and the emissions will be much higher than usual. The engine may also produce knocking or tapping noises, which is a sign that the fuel is not burning correctly.
Potential Damage to Your Vehicle
Driving a petrol car with diesel fuel in the tank can cause significant damage to the engine and fuel system. Diesel fuel can damage fuel injectors, fuel pumps, and fuel lines. Diesel fuel can also cause damage to the cylinder walls and pistons, which can lead to catastrophic engine failure. If you continue to drive the car with diesel fuel in the tank, you risk causing irreparable damage to your vehicle.
What to Do If You Put Diesel in a Petrol Car
If you have put diesel in a petrol car, the first thing you should do is stop driving the car and turn off the engine. Do not attempt to start the engine again, as this will only make the problem worse. If you have not started the engine, have the car towed to a mechanic to have the fuel system drained and cleaned. If you have started the engine and driven the car, you will need to have the car towed to a mechanic as soon as possible. The fuel system will need to be drained and cleaned, and any damaged components will need to be replaced.
The Cost of Repairing a Petrol Car with Diesel in the Tank
The cost of repairing a petrol car with diesel in the tank can vary depending on the extent of the damage to the engine and fuel system. In some cases, the damage may be minor and only require a fuel system flush. However, in more severe cases, the engine may need to be replaced, which can be a costly repair. To avoid these costs, it is important to be careful when filling up your tank and to take the necessary precautions to prevent putting diesel in a petrol car.
Putting diesel fuel in a petrol car is a mistake that can cause serious damage to the vehicle's engine and fuel system. If you make this mistake, it is essential to stop driving the car and have it towed to a mechanic to have the fuel system drained and cleaned. While it can be an expensive mistake, it is better to be safe than sorry and avoid significant damage to your car.
