Automotive additive aimed at reducing exhaust smoke from oil burning while improving oil viscosity and engine performance. Drivers of older or high‑mileage vehicles should notice quieter running and steadier response. Is Wynn's Stop Smoke the straightforward way to cut visible smoke and recover lost compression?
⚡ At a Glance
- • Smoke Reduction: Targets oil‑burning smoke by stabilising oil consumption and modifying combustion behaviour
- • Best for: Drivers of older or high‑mileage vehicles seeking lower visible smoke and improved performance
- • Not ideal for: Engines that require mechanical overhaul rather than additive treatment
Oil‑soluble engine additive (325ml) that reduces exhaust smoke and improves high‑temperature oil viscosity. Safe for use with catalytic converters, turbochargers and diesel particulate filters.
Reduce Visible Exhaust Smoke – thanks to oil‑soluble smoke‑reduction formula
Oil‑soluble chemistry mixes directly with engine oil and alters oil behaviour under combustion, reducing the tendency for oil to be drawn into the combustion chamber. Stabilised oil consumption leads to less oil present where it can ignite and create visible smoke.
Drivers should see less blue or grey smoke on start‑up and under load, helping emissions control and keeping exhaust systems cleaner.
Restore Compression and Cut Oil Consumption – with high‑performance sealing action
Sealing agents in the formula fill microscopic gaps between pistons, rings and cylinder walls, reducing internal clearances and helping to recover original compression levels. The action occurs without changing the fundamental chemistry of the engine oil.
Improved compression can restore lost power and reduce oil consumption in older or worn engines, making the engine feel more responsive.
Quieter Running and Improved Lubrication – thanks to enhanced viscosity stability at high temperatures
The additive reinforces the oil's viscosity index so the lubricating film remains effective under high thermal stress and heavy loads. Reduced metal‑on‑metal contact lowers friction and mechanical noise.
Engines run smoother with less mechanical noise, particularly during long journeys, summer driving or when towing heavier loads.

❓ Frequently Asked Questions
Q: Is it safe to use with catalytic converters, turbochargers and diesel particulate filters?
A: Yes. The product is specified as safe for use with catalytic converters, turbochargers and diesel particulate filters.
Q: Will it stop oil consumption and permanently repair a worn engine?
A: The additive helps stabilise oil consumption and seals microscopic gaps to restore compression, particularly in older or high‑mileage engines, but it rejuvenates worn areas rather than performing mechanical repairs.
Q: Which engines and oils are compatible?
A: Compatibility extends to all types of engine oils including mineral and synthetic, and suitability is indicated for passenger cars, light commercial vehicles and heavy‑duty machinery.
🏆 Our Verdict
Suitable for owners of older, high‑mileage cars and operators of light commercial or heavy‑duty vehicles who want to reduce oil‑burning smoke and recover lost compression. The oil‑soluble formula both improves high‑temperature viscosity and seals worn components to lower smoke and noise. As a maintenance measure, the additive offers a cost‑effective way to prolong engine life compared with major mechanical repairs.
