Mixing gas and diesel can lead to serious engine damage. Gasoline has a lower ignition point than diesel, so when mixed, it can cause the diesel to ignite prematurely. This might lead to engine knocking, reduced lubrication, and potential engine failure. If you accidentally mix them, do not start the engine. Instead, drain the fuel tank and refill it with the correct fuel. It's also wise to replace the fuel filter and consult with a professional mechanic to avoid costly repairs.
