Why do I need STP® Gas Treatment or STP® Fuel Injector & Carburetor Treatment?
These fuel additives are referred to as “Keep Clean” products. Just as brushing your teeth keeps harmful bacteria from building up on your teeth, STP® Gas Treatment and Fuel Injector & Carburetor Treatment help keep harmful deposits from building up in your engine’s fuel intake system, including fuel injectors and carburetors. It is important to keep your fuel system free of deposits in order to maintain maximum performance. These STP® products do not remove existing deposits. (See STP® Super Concentrated Gas Treatment, STP® Super Concentrated Fuel Injector Cleaner, STP® Octane Booster and STP® Complete Fuel System Cleaner for “Clean Up” products that help remove existing engine deposits, to restore lost performance and efficiency).
