Total waste of money if your motor is not designed or required to use it (check you owners manual). Detergent is mandated in all gas by the federal government. Some brands may use a tad more in their own formula but it is a negligible difference. It's all marketing folks....don't fall for it.

Use what your car is designed to use, buy it fresh, and keep your motor in good repair. That's the magic.
