Compatible with multiple fuel types and safe for emission systems, it prevents sludge build-up and supports cleaner, more efficient combustion—perfect for professionals seeking reliable, long-term engine care. ## 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.

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 ### ⭐⭐⭐⭐⭐ good value *by J***H on 7 June 2026* Good product ### ⭐⭐⭐⭐⭐ Useful engine Additive *by F***K on 30 June 2026* Seems good no problems.Engine is a bit quieter.Been in for a few thousand miles now!👍🙂 ### ⭐⭐⭐⭐⭐ Impressive stuff, to be fair *by R***R on 16 November 2025* 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. ## 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.co.uk/products/49425112-wynns-formula-gold-engine-oil-treatment-improves-compression-500ml-reduces](https://www.desertcart.co.uk/products/49425112-wynns-formula-gold-engine-oil-treatment-improves-compression-500ml-reduces) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-24*
