Mixing diesel and gas is highly inadvisable. These fuels have different ignitions points and are designed for distinct engine types. Using diesel in a gasoline engine can lead to serious damage including clogged fuel injectors and filters, reduced engine performance, or even a complete engine failure. Similarly, gasoline in a diesel engine can cause severe damage due to pre-ignition. If mixed accidentally, do not start the vehicle and seek professional assistance immediately to drain and clean the fuel system.
