STP Complete Fuel System Cleaner, Fuel Cleaner Deep Cleans Entire Fuel System,

STP Complete Fuel System Cleaner is a dedicated liquid fuel treatment formulated to deep clean an entire automotive fuel system. Designed for drivers seeking to maintain engine performance and fuel efficiency, it provides a straightforward maintenance solution added directly to the fuel supply.

The formula combines PEA and PIBA detergents to break down and clear away accumulated deposits within the system. It contains twice the cleaning agents found in leading premium gasoline, working to restore lost engine performance and inhibit internal corrosion across versatile car applications.

Because it comes in a compact 5.25 fluid ounce bottle, each purchase covers a single treatment. Routine maintenance requires planning ahead, as the recommended application schedule is once every oil change or every 4,000 miles, and the listing does not detail multi-vehicle batch sizes.
