## Overview

Wynn's Stop Smoke is a 325ml oil-soluble additive designed to dramatically reduce exhaust smoke caused by oil burning, especially in older or high-mileage engines. It improves oil viscosity at elevated temperatures, seals micro-gaps in worn engine components to restore compression, and reduces engine noise by enhancing lubrication. Compatible with all oil types and modern engine technologies, it supports cleaner emissions, smoother operation, and prolonged engine life without costly repairs.

## Description

This oil-soluble engine additive is specially engineered to tackle smoke emissions resulting from oil burning, offering an efficient solution to one of the most common issues in worn or high-mileage engines. Its multi-functional formula not only reduces visible smoke but also enhances oil viscosity at high temperatures, supporting better engine lubrication during thermal stress. The advanced chemical composition acts directly within the engine to seal micro-gaps between worn components, restoring compression and improving combustion quality. As a result, engines run smoother, with less noise and improved performance, without the need for costly mechanical repairs. Additionally, this oil additive is formulated to work as a protective agent under severe driving conditions. In high-load or high-temperature situations, it provides a reinforced oil film that resists breakdown and prevents metal-to-metal contact, helping maintain engine health over extended periods. It's compatible with all types of oils, including synthetic and mineral, and is safe for modern engine technologies such as catalytic converters and particulate filters, making it a universal choice. Whether addressing existing issues or used as a preventive measure, the additive supports cleaner emissions, longer engine life, and optimised driving performance. Designed to integrate easily into regular maintenance routines, it contributes to efficient engine care and operational stability under all driving conditions.

Review: Works Really Well! - I’m very happy with Wynn’s Stop Smoke. It arrived on time and was easy to use. I noticed a clear difference afterwards, the exhaust smoke reduced significantly, and the engine felt smoother and more responsive. It also seems to improve compression and overall performance. Great product and definitely worth trying if your car is burning a bit of oil!
Review: It actually worked - Gone from a lot of soot in the exhaust and burning oil, to very little. Really pleased with it. Will see how long it lasts but I can live with the odd can of this in comparison to constantly filling up the oil

## Features

- ✅ REDUCES EXHAUST SMOKE CAUSED BY OIL BURNING: Specially formulated to address the issue of excessive exhaust smoke, this oil-soluble additive helps reduce smoke emissions caused by oil burning. It works effectively within the engine to stabilise oil consumption, particularly in older or high-mileage engines, where internal components may be worn or degraded. The additive enhances the oil's behaviour under combustion conditions, allowing it to resist being drawn into the combustion chamber. This results in visibly reduced smoke output, making it ideal for improving emissions control and keeping exhaust systems cleaner for longer periods.
- ✅ IMPROVES OIL VISCOSITY AT HIGH TEMPERATURES: The formula is designed to enhance the thermal stability of engine oil, particularly at elevated temperatures that can thin out the oil and reduce its protective capabilities. By reinforcing the viscosity index, the additive ensures that the oil maintains its thickness and protective film even under demanding engine conditions. This not only prolongs engine life but also ensures optimal lubrication of all moving parts during high-performance or heavy-duty operations. The product is especially valuable in maintaining engine health during summer driving, long-distance travel, or when towing heavy loads.
- ✅ SEALS GAPS BETWEEN WORN ENGINE COMPONENTS: With a high-performance sealing action, the supplement minimises the adverse effects of wear and tear on engine components. By reducing the internal clearances between parts such as pistons, rings, and cylinder walls, it helps restore the original compression levels, boosting both performance and efficiency. This sealing function is crucial in older engines, where wear can lead to power loss, increased emissions, and excessive oil consumption. The product’s formulation supports the rejuvenation of worn areas without altering the engine's internal chemistry.
- ✅ REDUCES ENGINE NOISE AND IMPROVES PERFORMANCE: Engine noise often results from friction between metal components, especially when the oil film fails under pressure or heat. This additive reinforces the oil's lubricating properties, forming a durable film that cushions metal contact and reduces mechanical sound. With smoother movement of engine parts, the overall noise level is significantly reduced, leading to a quieter and more refined engine operation. In addition to noise reduction, the optimised lubrication contributes to better performance by decreasing internal resistance. This helps restore lost power and fuel efficiency in engines affected by wear or oil degradation.
- ✅ SAFE FOR USE WITH ALL OIL TYPES AND ENGINE COMPONENTS: The supplement is universally compatible with all kinds of engine oils, including mineral, synthetic, single-grade, and multigrade variants. Its chemical formulation is engineered to integrate seamlessly without causing side effects or degradation of oil quality. It is safe for use in vehicles equipped with catalytic converters, turbochargers, and diesel particulate filters, making it a reliable choice across a wide range of engine types and configurations. Whether in passenger cars, light commercial vehicles, or heavy-duty machinery, the product maintains its performance without compromising sensitive engine technologies.

## Questions & Answers

**Q: Can this be used in a Toyota diesel 2.2 ,all of a sudden car is smoking white and blue**
A: Hi, you can use it. Has the car been sat around a lot? White smoke is often due to condensation

**Q: can you add it when the oil is already at the max level?**
A: Hi, no do not over fill your oil level. Wait until your oil level drops or drain it then top up with this full can.

**Q: I have a Cherokee jeep that smoke white on start and black when you accelerate is this oil any good**
A: For an older engine that has wear I would highly recommend as it's a cheap fix although not a permanent one. If the wear is bad then mechanical attention is needed. White smoke can be a sign of possible head warp where the gadget has gone hence coolant enters the engine producing white smoke the dark smoke can indicate oil entering the combustion system which could be valve seals. Hope this helps. Try the product and see if it helps and use upon every oil change.

**Q: My car uses 0w20 oil which is quite thin. Will this be suitable? It's a Toyota**
A: It did not work on my Honda
