Purpose and Specifications

STP Smoke Treatment is a 450ml oil additive designed for gasoline engines to cut down exhaust smoke and oil burning in worn motors. It creates a thicker oil film that seals gaps in cylinder walls, piston rings, and valve guides caused by wear, helping your engine run cleaner with less blue smoke puffing out the tailpipe.

When to Use / Replace?

Add STP Smoke Treatment when you notice blue exhaust smoke on startup or acceleration, especially in high-mileage cars over 150,000km. Ideal for engines operating in everyday temps from -10°C to 120°C where oil blow-by lets oil slip into the combustion chamber. Use every 5,000-10,000km or at each oil change to maintain benefits; shelf life is 3-5 years unopened in a cool, dry spot.
