What to Do After Putting Diesel in a Gasoline Car?
2 Answers
It is necessary to immediately stop the motor vehicle, turn off the engine, drain all the fuel from the fuel tank, clean the vehicle's fuel lines, replace the gasoline filter, clean the fuel pump, flush the fuel tank, and clean the fuel injectors to effectively resolve the issue of using the wrong fuel. Additional information is as follows: 1. Gasoline: Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, mainly composed of C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. 2. Diesel: Diesel is a light petroleum product, a complex mixture of hydrocarbons (with carbon atoms numbering approximately 10 to 22). It serves as fuel for diesel engines. It is primarily produced by blending diesel fractions obtained through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking.
I have personal experience with this. When I first started driving, I accidentally put diesel into a gasoline car. After driving a few dozen meters, the car started shaking abnormally. I quickly stopped and turned off the engine but still tried to start it, resulting in the engine seizing up and costing me thousands in repairs. From that lesson, I learned: if you fill up with the wrong fuel, you must immediately turn off the engine and not touch the key. Contact a towing service to take the car directly to a professional repair shop. They will use equipment to drain the fuel tank, clean the fuel system, and inspect components like fuel injectors and fuel pumps to prevent severe damage. Always check the label when refueling—gasoline cars should only use 92 or 95 octane unleaded gasoline. Don’t rush like I did and make a mistake. Mishandling this could damage the catalytic converter, leading to repair costs in the tens of thousands. Safety first—don’t take risks.
