Old gas can indeed ruin a car engine. Over time, gasoline can degrade, leading to varnish and gum deposits that clog fuel injectors, carburetors, and other parts. This could cause poor engine performance, difficulty in starting, or even engine damage. To avoid these issues, use a fuel stabilizer if you plan to store your car for an extended period, and always use fresh gas as much as possible.
