Yes, even a small amount of diesel can harm a gas engine. Diesel fuel does not evaporate in a gas engine like gasoline does, which can lead to engine misfires, reduced power, and a thick smoke output. Continuing to run a gas engine on diesel can cause serious damage to the fuel system and engine components. The best solution is to drain the fuel tank and refill it with gasoline as soon as possible to minimize damage.
