STP Smoke Treatment Engine Oil Additive 450mL (SKU: 5018704345117) is a professional-grade, high-viscosity chemical fluid engineered in the USA to mitigate and control excessive exhaust emissions in passenger vehicles. Specially formulated for petrol-driven architectures, this advanced treatment blends into the existing engine oil to build a thick, protective anti-wear fluid cushion. This fortified layer seals the mechanical tolerances between worn piston rings and cylinder walls, preventing lubricating oil from escaping into the combustion chambers. By optimizing thermal chemical burn cycles, it dramatically lowers the presence of unburnt fuel and reduces black exhaust smoke, resulting in significantly lower oil consumption parameters and a quieter, smoother engine idle.

Key Features & Performance:
-
Instant Black Smoke Suppression: Actively cuts down visual smoke emissions from the tailpipe, helping vehicle owners maintain compliance with environmental baselines.
-
Reduces Oil Consumption Rates: Effectively minimizes internal oil blow-by and oil loss past the valves, preventing costly and recurrent oil top-offs.
-
Deploys a Thick Protective Oil Cushion: Cushions moving metallic parts against severe dry friction, heavy load stress, and premature mechanical wear.
-
Restores Performance & Burn Efficiency: Promotes high-quality fuel atomization and complete burning, optimizing power delivery and maximizing fuel usage profiles.
-
Inhibits Sludge & Carbon Structuring: Prevents hard carbon varnishes and combustion soot from layering over interior engine walls, prolonging structural engine life.
-
Zero Mechanical Modifications Required: Easily blends into the fresh or current engine oil matrix during routine service intervals without demanding workshop tear-downs.
Usage Instructions:
-
Ideally applied directly during a fresh engine oil and filter replacement service, or introduced between intervals when exhaust smoke issues arise.
-
Ensure the vehicle is parked on flat ground and the ignition is turned off completely.
-
Remove the engine oil filler cap from the valve cover and pour the entire contents of the 450mL STP Smoke Treatment bottle into the crankcase.
-
One 450mL bottle is chemically measured to treat standard passenger car oil capacities ranging from 4 to 5 liters of engine oil (approx. 10% treat rate).
-
Replace the oil cap securely, start the engine, and drive the vehicle for a short trip to enable the additive to thoroughly cross-link and circulate with the oil.
Suitability & Applications:
-
Formulated and safety-certified exclusively for all varieties of petrol passenger cars, SUVs, and light trucks, seamlessly blending with all mineral, semi-synthetic, and fully synthetic engine oil classes.
Note:
This formulation is a dedicated oil additive engineered solely to blend with engine lubricating oil; never attempt to pour this thick liquid into the fuel tank, radiator expansion tank, or brake fluid reservoir, and do not utilize it in diesel engine systems. Adhere strictly to the recommended application volumes to avoid forcing oil pressures past nominal operational safety parameters.
