The symptoms of putting the wrong fuel in your car are: 1. The car lacks power and the body shakes severely; 2. The car emits black smoke; 3. If the diesel ratio is high, the car will fail to start; 4. A large amount of carbon deposits will form, adhering to the top of the piston. If you discover that you have added the wrong fuel and have not started the car, simply draining the fuel tank completely will suffice, and it will have no impact on the car. If you realize it after driving for a while, you should thoroughly clean the fuel tank. At this point, you need to remove the fuel tank, pour out all the fuel, including the fuel in the fuel pump, then clean the fuel tank, fuel lines, and combustion chamber, replace the fuel filter, and add gasoline to resume normal use.
