What to Do If a Diesel Car is Filled with Gasoline?
2 Answers
If you realize that the wrong fuel has been added, the first thing to do is to assess the amount of gasoline added. If only a small amount of gasoline has been added recently, no immediate action may be necessary. Here are the details: 1. Since the ignition point of diesel is much higher than that of gasoline, the diesel car can still be started after adding gasoline because the diesel engine can easily ignite the gasoline under compression. However, over time, abnormal idling and white smoke from the exhaust pipe may occur. 2. If you have been driving for a while before noticing the issue, regardless of whether the car can still run, you should stop immediately. Call a tow truck to move the car to a 4S shop or repair shop, drain all the gasoline from the fuel tank, and then perform necessary cleaning of the fuel tank, engine, and fuel lines, as well as replace any damaged parts.
If you accidentally fill your diesel car with gasoline, never start the engine—this is absolutely crucial! As soon as I noticed, I immediately turned off the power and safely parked the car on the roadside. Call a towing service right away to transport the vehicle to an authorized repair shop. There, technicians will use professional equipment to completely drain the fuel tank and fuel lines, while also checking for any damage to the fuel pump and injectors. The process typically costs a few thousand dollars and takes a day or two to complete. This is because gasoline burns completely differently in a diesel engine, causing instant damage to internal components—ranging from minor part repairs to a full engine replacement. After this incident, I learned to add a fuel cap sticker as a reminder to avoid such mistakes in the future. Safety comes first; don’t treat it as a minor issue. Swift, professional handling is the only solution to prevent further complications down the line.
