What are the issues if a gasoline car is filled with diesel engine oil?
1 Answers
Filling a gasoline car with diesel or diesel engine oil can cause difficulties in starting the vehicle. During driving, the exhaust pipe may emit smoke, and there is a high likelihood of damage to the catalytic converter. Below is an introduction to the related content: Although both gasoline and diesel engines are internal combustion engines, diesel has a lower auto-ignition point, around 220°, whereas gasoline has a much higher ignition point, between 410° and 430°. Therefore, diesel engines use compression ignition and do not require spark plugs for ignition. They rely on compressing air to raise the temperature to the diesel's ignition point, then inject diesel, which auto-ignites. Consequently, if diesel enters a gasoline engine, it will start burning violently on its own before the spark plug ignites, causing abnormal pressure in the combustion chamber, commonly known as knocking. This will also be accompanied by other engine abnormalities. Once it is discovered that the issue is caused by mistakenly adding diesel, it is crucial to stop attempting to start the engine to prevent diesel from entering the fuel system. Then, take the car to a 4S shop or repair shop to drain the diesel completely and refill it with gasoline.
