My sister put gasoline in her diesel car and now she might have to get a new car. I don’t even have a driver’s license and have a rudimentary understanding of how simple combustion engines work. Why is the car maybe dead, can it be fixed?
In: Engineering
Diesel is oily, gasoline is not.
Diesel engines are generally designed with this in mind. The fuel lubricates some very precise and expensive parts of the fuelm system, such as the high pressure fuel pump and fuel injectors.
Without this lubrication (ie, if you use gasoline instead of diesel) these parts can be damaged. The cost of replacing them can be enough to total the vehicle.
**If you misfuel your vehicle, do not attempt to start the engine**. It is relatively easy to have the fuel tank drained. It is less easy to have the whole fuel system drained and flushed. It is complex to have the whole fuel system replaced if you ran the car and damaged those parts.
