There are a number of problems that can arise when you accidentally pump 5 litres of diesel into a petrol car. For example, if you have accidentally put more diesel than petrol into your car, you may be unable to start the engine. In this situation, you should drain the fuel from the car and contact a mechanic. If possible, push the car to a safe location and inform the mechanic to flush the fuel.
This can lead to serious problems for your car. For one, you might end up with a dirty engine, which will cause excessive smoke. Additionally, you might end up with a damaged high pressure injection pump. Another problem can occur if you mix petrol with diesel, as it will damage the seals and the high pressure injection pump. Thankfully, there are a number of easy fixes. If you misfuel your car, the simplest way to repair the problem is to drain the tank, and flush out the fuel system.
Another problem caused by diesel in petrol cars is that it has less combustibility. While the car may smoke a little, the engine will run hotter than it should. This can cause damage to the car’s pistons. This issue is easily remedied by calling a mechanic and ensuring that the vehicle is in limp mode while it is being repaired. It’s best to leave the car in this state until the problem is resolved.
