Gasoline car added diesel treatment method: Stop the vehicle and turn off the engine immediately, then contact a repair shop for cleaning. This includes cleaning the engine, fuel tank, and fuel lines, as well as replacing the gasoline filter. Only by doing so can the occurrence of vehicle malfunctions be reduced, avoiding the risk of engine failure. To prevent adding diesel when refueling with gasoline, here are some precautions: 1. Avoid refueling at unofficial gas stations and do not operate the pump yourself. At official gas stations, the attendant will ask what type and grade of fuel you need. 2. Stay calm when refueling and always check the station's instructions. Park your car in the designated area and observe the vehicles ahead. If the vehicle in front is a truck or agricultural vehicle, there's a high chance you're in the wrong place.
I've been in the auto repair industry for over a decade and often encounter cases of misfueling. When diesel is added to a gasoline car and driven, the viscosity and ignition point of diesel are unsuitable for gasoline engines, leading to clogged fuel injectors, poor combustion, and symptoms like engine shaking, loss of power, or even stalling. Realizing the mistake after driving makes it worse, as the fuel has already circulated throughout the system. The first step is to immediately stop the car and turn off the engine—do not attempt to restart it to avoid further damage to internal components. Then, contact a towing service to transport the vehicle to a professional repair shop or dealership. There, specialized equipment will be used to drain the fuel tank, clean the entire fuel system (including the fuel pump and injectors), and possibly replace the fuel filter while assessing the engine's condition—repair costs can range from a couple thousand to over ten thousand yuan, depending on the distance driven and extent of damage. The lesson learned: always double-check the fuel pump label when refueling instead of relying solely on the attendant’s reminder, preventing such unnecessary expenses and hassle.
