STP Fuel Injector Cleaner is a product that can be added to your gas tank to unclog dirty fuel injectors and help your car start more smoothly. It is designed to dissolve and remove harmful deposits, such as carbon, gum, and varnish, that can build up in your fuel system over time. These deposits can lead to hard starts, lost acceleration, and rough idling. The frequency of use varies depending on the source, with some recommending it every oil change or 4,000 miles, and others suggesting every 10,000 miles. The amount to be used also depends on the size of the bottle and the capacity of your gas tank, with a 5.25 fl. oz bottle treating up to 15-21 gallons of gasoline, and a 12 fl. oz bottle treating 21-28 gallons. While some users have noticed improvements in their vehicle's performance, others believe it to be an unnecessary expense, as modern gasolines already contain additives that help clean the engine and combustion chamber.
