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

1.97K 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?

Unless your sister hydrolocked the engine (which is possible) then a new engine shouldn’t be needed – open up the fuel line to the rail, jump the fuel pump relay, and let the pump take all the gas out of the tank.

Fill up with diesel and run the pump again until diesel comes out.

Change the oil in the engine as it’s possible some gas could mix with the oil and that’s bad for the cylinder walls.

After that, it should run fine. May be tough to get it started.
