STP Ultra 5-in-1 Petrol System Cleaner Gold Edition 400mL (SKU: 5020144852124) is a professional-grade, highly concentrated fuel treatment compound engineered in the USA to deliver a comprehensive maintenance regimen for passenger vehicle fuel architectures. Operating as an advanced 5-in-1 technical formula, this premium gold treatment targets, liquefies, and removes stubborn carbon crusts, accumulated gums, and frozen varnishes embedded within fuel injectors, intake valves, and the combustion chamber cylinder crowns. Fortified with cutting-edge power boosters and STP's signature "Wear Guard" friction modifiers, it minimizes parasitic mechanical resistance and optimizes fuel atomization, successfully restoring factory horsepower, boosting throttle response, and yielding significant improvements in fuel economy metrics.

Key Features & Performance:
-
Ultimate 5-in-1 Action Matrix: Delivers five critical field benefits in one single bottle: saves fuel, restores peak engine performance, cleans deep deposits, reduces internal friction, and inhibits structural corrosion.
-
Deep Injection & Valve De-carbonization: Purges heavy industrial grime, frozen grease tracking, and soot from delicate injector nozzles, ensuring an unhindered fuel spray mist trajectory.
-
Restores OEM Horsepower & Idle Balance: Eliminates critical engine hesitation, dynamic flat spots, and rough idle cycles by maximizing chemical fuel burn and energy translation parameters.
-
Measurable Reductions in Fuel Consumption: Enhancing internal thermal combustion efficiency allows the engine architecture to harvest more power per drop, minimizing fuel waste.
-
Advanced Wear Guard Protection: Deposits a specialized synthetic lubrication layer over moving metallic parts within the fuel system to deter friction wear and premature component degradation.
-
Universal Catalytic Converter Safety: Exclusively safety-certified for seamless implementation across all classic and modern automotive powertrains, fully neutral toward catalytic converters and exhaust sensors.
Usage Instructions:
-
Ensure that the vehicle ignition is turned off and the engine is completely cool before starting the chemical application.
-
Pour the entire contents of the STP Ultra Gold 400mL bottle directly into the vehicle's empty or nearly depleted fuel tank.
-
Immediately refill the tank to maximum capacity with petrol (the 400mL chemical concentration is balanced to treat standard passenger car fuel tanks).
-
Start the vehicle and drive for a short distance on the highway to allow the treated fuel mixture to actively circulate and cleanse the injection paths; recommended for re-application every 4,000 miles (approx. 6,400 km) to preserve pristine operation.
Suitability & Applications:
-
Formulated and laboratory-certified for all grades of regular petrol, premium unleaded fuel configurations, and bio-petrol blends across passenger cars, sports utilities, and light transport trucks.
Note:
This formula is an ultra-concentrated chemical fuel system treatment engineered solely to blend with petrol; never attempt to introduce this fluid into diesel engine architectures, crankcase lubricating oils, or radiator cooling systems. Avoid splashing the fluid onto the exterior bodywork to prevent paint discoloration, and keep the pressurized canister clear of open solar corridors or active workshop ignition sparks.
