Putting diesel in a gas engine can lead to significant damage. Diesel fuel doesn't evaporate like gasoline and has a different combustion process. When diesel is mistakenly used in a gas engine, it can clog the fuel injectors and filter, lead to poor engine performance, and potentially cause the engine to stall or not start. To rectify this mistake, the fuel tank should be drained completely and filled with gasoline. In severe cases, it might be necessary to clean or replace the fuel lines, injectors, and filters.
