Anti-Fume Treatment 450ml STP

Petrol Smoke Treatment 450ml STP
This product is ideal for petrol engines to provide a thick cushion of oil that helps fill the spaces created between cylinder walls, piston rings and valve guide gaskets in worn engines and reduce oils resulting from combustion and smoke.
The anti-smoke treatment reduces tailpipe smoke, engine noise and oil consumption and protects the engine against wear. It can also be used on diesel engines if it has been determined that burning oil is the cause of excessive exhaust pipe smoke.
INSTRUCTIONS: Add to engine oil or between oil changes. One 450ml bottle will fit 4 or 5 litres of oil (10% ratio).
