78571 Fuel Injector & Carburetor Treatment, 5.25 Oz.

STP Fuel Injector & Carburetor Treatment is a high-performance fuel system cleaner formulated to maintain clean performance of fuel injectors and carburetors by helping prevent the accumulation of deposits. The product is made with jet fuel as a carrier of active ingredients, delivering powerful cleaning action throughout your fuel system. Without cleaning, deposits can lead to hard starts, lost acceleration, and rough idling—problems that affect both engine performance and your driving experience.

This treatment penetrates deep into fuel passages to dissolve stubborn carbon and varnish residues while reducing internal friction for smoother engine operation. The convenient 5.25-ounce bottle with precision applicator makes it easy to add to your fuel tank for regular maintenance or occasional top-ups, whether you're a DIY enthusiast or managing an auto shop fleet.
