Yes, gasoline can severely damage a diesel engine. Diesel engines rely on the lubricating properties of diesel fuel; gasoline lacks this lubrication and can cause wear and tear. Additionally, gasoline's higher volatility can cause premature combustion, leading to engine knock and damage to pistons, cylinders, and other components. If gasoline has been added to a diesel tank, do not start the vehicle. Instead, have the fuel system drained and inspected by a professional to prevent extensive damage.
