Additive STP Petrol Stop Smoke 450ML

STP® Petrol Stop Smoke was developed to create a thick lubricating layer that helps fill the spaces formed between the cylinder walls, piston rings and valve guides in worn engines. This action reduces oil consumption and exhaust vapour emissions, while protecting the engine from premature wear. Although formulated for petrol engines, it can also be used in diesel engines when oil burning is the cause of excessive smoke.

Main benefits: 

• Reduces exhaust smoke.
• Decreases oil consumption.
• Reduces engine noise.
• Protects against wear.
• Restores performance in worn engines.

How to use

1. Add directly to the engine oil during or between oil changes.
2. Dosage: 1 bottle of 450 ml for 4 to 5 litres of oil (10% ratio).
