Wynns Stop Smoke is a specialized oil treatment designed to reduce excessive exhaust smoke and oil consumption in gasoline and diesel engines. This effective 325ml formula contains advanced polymers and viscosity stabilizers that help seal worn valve guides, piston rings, and cylinder walls, reducing oil burning and the resulting blue-gray exhaust smoke. The multi-action formula also helps maintain proper oil pressure in worn engines while providing enhanced lubrication to critical engine components, extending engine life and improving performance.

Key Features

• Smoke Reduction: Significantly decreases blue-gray exhaust smoke
• Oil Consumption Control: Reduces oil burning through worn engine components
• Viscosity Stabilization: Maintains proper oil viscosity at all temperatures
• Compression Improvement: Helps restore compression in worn cylinders
• Seal Enhancement: Improves sealing of worn valve guides and piston rings
• Oil Pressure Maintenance: Helps maintain proper oil pressure in worn engines
• Engine Quieting: Reduces engine noise caused by wear and poor lubrication
• Wear Protection: Provides enhanced protection to critical engine components
• Compatible with All Oils: Works with conventional, semi-synthetic, and full synthetic oils
• Cost-Effective Solution: Extends engine life without major mechanical repairs

How to Use

Add entire contents to the engine oil when the engine is at normal operating temperature. One 325ml bottle treats 4-6 liters of engine oil. Drive normally, allowing the product to circulate through the oil system. Results may begin to show within 100-200 miles of driving, with maximum effectiveness typically achieved within 300-500 miles. For ongoing treatment of high-mileage engines, use with every oil change. For severe smoke issues, a second treatment may be used at the next oil change if needed.

Stop Smoke is particularly valuable for addressing blue-gray exhaust smoke in high-mileage engines with worn valve guides, valve seals, or piston rings. This product provides a cost-effective solution for extending engine life and reducing embarrassing smoke emissions without requiring expensive engine rebuilding. Not intended to address white smoke (coolant leaks) or black smoke (fuel combustion issues). For comprehensive engine treatment in high-mileage vehicles, consider combining with Wynns Engine Flush before the next oil change for maximum effectiveness.
