what happens when you put gasoline in a diesel car and vice versa

1.96K viewsEngineeringOther

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?

Diesel in a gasoline car won’t burn, it’ll sit in the sump and exhaust. Happened to me.
Gasoline in a diesel car might very well incinerate the car. Happened to my sister.
Modern cars adjust ignition timing and fuel/air mix to try to optimise economy/power, and that can help the car run a bit longer but they will fail, and pre-ignition in the diesel running on petrol is fairly likely to be catastrophic and life threatening.
