Trusted by professionals and everyday drivers alike, it ensures long-term engine reliability and efficiency.

## Description

This advanced 500ml chemical oil treatment is engineered to enhance engine performance, protect critical components, and promote long-term reliability. The formulation features a unique double-action mechanism —improving compression and reducing mechanical wear — ensuring smooth engine operation under a variety of conditions. Its impact on oil viscosity and stability helps prevent premature thickening of new oil, maintaining optimal lubrication across a wide temperature range. This results in better cold start performance, reduced mechanical stress, and improved overall oil longevity. The treatment also plays a crucial role in engine cleanliness by preventing the build-up of sludge and deposits, which are known to restrict oil flow and reduce efficiency. By keeping the oil system clean, the product ensures continuous protection of internal parts, which contributes to lower wear and fewer maintenance issues over time. Enhanced combustion efficiency, stemming from better compression, supports reduced oil consumption and fewer harmful emissions, aligning with modern environmental standards. Fully soluble in oil and free from solid particles, the formulation is safe for use with catalytic converters and modern emission control systems. Its broad compatibility with various oil types and engine configurations — including petrol, diesel, LPG, and hybrid — makes it a versatile addition to routine engine care. A single 500ml bottle effectively treats between 4 to 6 litres of oil, making it practical for use in a wide range of vehicles. Designed to meet the demands of both everyday drivers and high-performance engines, this treatment is a reliable solution for maintaining engine health and optimising performance.

Review: Used in three vehicles with varying results - Wynn's Formula Gold Engine Oil Treatment. I first tried this product a few weeks ago on an engine that had just clocked 100,000 miles. I did NOT change the engine oil before adding it, as changing the oil alone can make quite a difference to engine performance, and I wanted to see if I could feel any difference in the engine by using the product with the existing oil. The first engine I tried it on was getting a bit noisy, and starting to feel quite tired. We service our vehicles regularly, and always use the best Castrol oils, so I didn't really expect to see too much of a difference, but I was really surprised at the results. There was quite a bit more punch to the engine after adding it. The change in performance still seems to be there several weeks later. After being impressed with the product with the first trial, about a week ago, I tried it on another car we have that has also just crossed 100,000 miles, and again, the effect was very noticeable. The engine seems much quieter and smoother. Finally, yesterday, I added it to a third car that has just 75,000 miles on the clock to gauge the effect. The engine in this car was still running quite well, and this time the effect wasn't nearly as noticeable. The improvement was slight. So my initial impressions of this product are: A) Much to my surprise, it does actually work B) It seems to work better in some engines than others, with higher mileage cars perhaps benefitting more. C) It seems like quite a good deal if you want to add a bit of perk to a jaded engine. Just to repeat, with all three cars, we did NOT change the oil first.
Review: Impressive stuff, to be fair - Fair play, this is actually impressive stuff. It sure how much difference it would make with fresh oil after a change but with existing, older oil it has made a world of difference: engine runs smoother AND quieter (particularly at lower speeds) and there does seem to be a general increase in power. Careful not to overfill the engine when you pop it in, mind.

## Features

- Causes serious eye damage.
- Harmful to aquatic life with long lasting effects.
- ✅ DOUBLE ACTION FORMULA FOR ENGINE OPTIMIZATION: Formulated as a fully oil-soluble chemical treatment, this product delivers a powerful double action for engine efficiency. First, it improves engine compression, which supports consistent power delivery and enhanced performance. Second, it actively reduces wear on internal engine components, contributing to long-term reliability. By targeting two essential engine functions simultaneously, the treatment not only stabilises mechanical operation but also supports smoother running under varying driving conditions.
- ✅ ENHANCED OIL PERFORMANCE AND VISCOSITY CONTROL: Designed to reinforce the oil's protective properties, this treatment significantly improves the oil’s viscosity index, enabling it to perform better across a wider range of temperatures. It delays the premature thickening that can affect fresh oil, ensuring the lubricant retains its flow characteristics even in extreme conditions. The formulation enhances the oil’s structural integrity, promoting longer service intervals and consistent lubrication performance.
- ✅ SLUDGE CONTROL AND SYSTEM CLEANLINESS: By actively reducing the formation of sludge and harmful deposits, this chemical treatment helps maintain a clean and efficient oil system. Sludge build-up can clog oil passages, impair circulation, and reduce engine efficiency. The advanced formulation dissolves existing contaminants and prevents the accumulation of new residues, safeguarding the engine’s internal components from abrasive particles and sticky deposits. Regular use promotes better oil flow, reduces frictional losses, and ensures that oil filters and galleries remain clean and unblocked.
- ✅ LOWER EMISSIONS AND REDUCED OIL CONSUMPTION: The treatment contributes to reduced oil consumption and minimises the release of harmful exhaust emissions. By enhancing oil stability and improving engine sealing through better compression, less oil is burned during engine operation. This directly leads to fewer particulates and hydrocarbons being emitted into the atmosphere. Lower oil consumption also means fewer top-ups are necessary, resulting in better cost-efficiency and environmental sustainability. The product’s role in keeping internal parts clean and operating at peak efficiency further ensures optimal combustion and reduced emissions.
- ✅ UNIVERSAL COMPATIBILITY AND SAFE FORMULATION: This treatment is free from solid particles, ensuring it will not damage engine components or catalytic converters. Its fully oil-soluble nature allows for seamless blending with all grades of engine oil, including synthetic, semi-synthetic, and mineral-based types. It is suitable for both regular and low SAPS (sulphated ash, phosphorus, and sulphur) applications, making it an ideal choice for a wide variety of engine types. Compatible with petrol, diesel, LPG, and hybrid engines, this product is designed for flexibility and convenience. A single 500ml bottle is effective for oil volumes ranging from 4 to 6 litres.

## Questions & Answers

**Q: Do you just put this in with the oil? Do you still need to keep the oil level at the same level? Or do you just add this in top of the current oil?**
A: Hi, You should take care not to overfill the oil. Add this if the engine has enough room before the Maximum, if you wish to add it now. But if you can, wait till an oil change for the best results. Thanks

**Q: Can you use it in Diesel engines**
A: Taken from description - Wynn's Formula Gold High Performance Engine Treatment is suitable for use with both petrol or diesel engines.

**Q: Will this break down emulsion sludge already built up?**
A: Hi, for that you really want a flush, like the Millers Engine Flush.

**Q: Is this suitable for motorcycles please**
A: I wouldn't if you have a wet clutch, its possible it could make clutch slip.
