It cleans engine internals by preventing sludge buildup, enhancing cold start performance, and supporting emission control systems. Compatible with petrol, diesel, LPG, and hybrid engines, it treats 4-6 liters of oil, making it a versatile, high-performance solution trusted by drivers seeking smoother, quieter, and more efficient engine operation. ## 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: 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. Review: Does as it says - Good product, self explanatory use and it does what it says on the tin. Definitely reduces oil consumption ## Features - Causes serious eye damage. - Harmful to aquatic life with long lasting effects. - car parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0074FWTSK | | Best Sellers Rank | 5,219 in Automotive ( See Top 100 in Automotive ) 17 in Engine Oil Additives | | Brand | Wynn's | | Customer Reviews | 4.6 4.6 out of 5 stars (272) | | Date First Available | 21 Aug. 2010 | | Item Weight | 500 g | | Item model number | 77101 | | Manufacturer | Wynn Oil UK | | Manufacturer part number | 77101 | | Model | Formula Gold Engine Treatment | | Product Dimensions | 9.2 x 4.6 x 23.7 cm; 500 g | ## Images ![WYNNS Formula Gold Engine Oil Treatment - Improves Compression - 500ml | Reduces Wear - Enhances Oil Viscosity & Cleans Engine Internally - Image 1](https://m.media-amazon.com/images/I/51gO5UlGT1L.jpg) ![WYNNS Formula Gold Engine Oil Treatment - Improves Compression - 500ml | Reduces Wear - Enhances Oil Viscosity & Cleans Engine Internally - Image 2](https://m.media-amazon.com/images/I/51b5Ct6foWL.jpg) ![WYNNS Formula Gold Engine Oil Treatment - Improves Compression - 500ml | Reduces Wear - Enhances Oil Viscosity & Cleans Engine Internally - Image 3](https://m.media-amazon.com/images/I/71yHgoMAN7L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive stuff, to be fair *by R***R on 16 November 2025* Fair play, this is actually impressive stuff.

Definitely reduces oil consumption ### ⭐⭐⭐⭐⭐ Used in three vehicles with varying results *by H***Y on 13 March 2024* 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. ## Frequently Bought Together - WYNNS Formula Gold Engine Oil Treatment Increase Compression And Reduces Wear Petrol & Diesel - Wynn's Formula Gold High-Performance Petrol System Treatment - Enhances Engine Efficiency - Improves Acceleration & Reduces Noise - Cleans & Protects Fuel Injection System - 500ml - Wynn's Formula Gold High Performance Diesel System Treatment 500ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/49425112-wynns-formula-gold-engine-oil-treatment-improves-compression-500ml-reduces](https://www.desertcart.us/products/49425112-wynns-formula-gold-engine-oil-treatment-improves-compression-500ml-reduces) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-25*
