It prevents premature wear, reduces friction, and guards against micro-welding. Additionally, it stabilizes fuel during long-term storage to prevent oxidation and residue buildup, keeping fuel systems clean and efficient. Suitable for a wide range of petrol engines including motorcycles, classic cars, lawn mowers, and marine equipment, this additive ensures enhanced engine durability and consistent performance across all applications. ## Description This high-performance fuel additive is formulated to safeguard the valve seats in engines running on unleaded petrol by forming a lubricating and protective film that replicates the cushioning effect of lead, traditionally found in older fuel compositions. This artificial layer prevents direct metal-to-metal contact, reducing friction and thermal stress on engine components and minimising the risk of micro-welding, particularly on soft valve seats commonly found in small and classic engines. Beyond mechanical protection, this product also plays a crucial role in fuel preservation. When petrol is stored for long periods — such as in seasonal equipment, backup generators, or marine engines — oxidation can severely compromise fuel quality. This additive halts oxidation by stabilising the hydrocarbons in the fuel, effectively preventing the formation of gum, varnish, and deposits that clog filters and reduce engine efficiency. Moreover, the formulation ensures that the entire fuel system remains free from corrosion and sediment build-up. Its cleaning action promotes consistent engine starts, even after months of inactivity. Designed for both two-stroke and four-stroke petrol engines, its application spans a wide array of vehicles and equipment including motorbikes, lawn mowers, scooters, and outboard boat engines. Whether used to maintain a daily vehicle or to preserve stored fuel in a seasonal machine, this additive provides reliable, long-lasting protection for both the engine and its fuel. Review: Works really well and easy to dispense. Review: Een issue met de levering werd snel en netjes door de verkoper opgelost ## Features - ✅ VALVE SEAT PROTECTION FOR UNLEADED PETROL ENGINES: Ensures optimal protection for valve seats in engines that run on unleaded petrol. In the absence of lead, which previously served as a natural lubricant, this formulation replicates the same protective effect by forming a resilient lubricating coating on valves and valve seats. This artificial barrier significantly reduces friction and wear, particularly in soft valve seats, preventing the formation of micro-welding caused by high operating temperatures and pressures. As a result, engine longevity is enhanced and performance remains consistent, even under demanding conditions. - ✅ PREVENTS PREMATURE WEAR IN CLASSIC AND MODERN ENGINES: Specifically designed to guard against the premature deterioration of soft valve seats in engines fuelled with unleaded petrol. The formulation creates a durable protective layer that mimics the lubricating properties of lead, reducing metal-to-metal contact and the risk of pitting and micro fusion. This protective action ensures that internal components maintain their integrity longer, helping to prevent performance issues and costly repairs. - ✅ OXIDATION PROTECTION FOR LONG-TERM STORAGE: Provides a vital layer of defence against fuel degradation during periods of inactivity. When engines are not in use for extended durations — such as during winter or seasonal storage — fuel left in the tank is prone to oxidation. This process can produce sticky residues and corrosive by-products that lead to blockages in fuel lines, filters, and injectors. The advanced chemical composition of this product stabilises the fuel, preventing oxidation and extending its usable life. - ✅ KEEPS FUEL SYSTEMS CLEAN AND EFFICIENT: Designed not only to protect but also to maintain the cleanliness of the entire fuel system. By preventing the formation of oxidation residues, this product avoids the build-up of deposits in the tank, filter, and carburettor, which could otherwise compromise fuel flow and combustion quality. Cleaner fuel systems contribute to improved engine efficiency, reduced emissions, and smoother performance. The stabilising agents work continuously to preserve fuel clarity and quality, especially in older or infrequently used machines where contamination risks are higher. Compatible with all petrol-powered two-stroke and four-stroke engines. - ✅ VERSATILE USE FOR MULTIPLE ENGINE TYPES: Suitable for a wide range of petrol engines including those found in motorcycles, classic cars, lawn mowers, scooters, generators, and marine equipment such as yachts and outboard engines. Whether for recreational, domestic, or utility purposes, this additive enhances engine durability and fuel stability across all applications. Its protective formula ensures consistent performance regardless of engine size or usage frequency, making it a reliable choice for both daily drivers and seasonally operated machines. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DZTOZI | | Batteries | Lithium Ion batteries required. | | Best Sellers Rank | #206,313 in Automotive ( See Top 100 in Automotive ) #544 in Automotive Greases & Lubricants | | Brand | Wynn's | | Customer Reviews | 4.7 4.7 out of 5 stars (614) | | Date First Available | 17 August 2012 | | Item Weight | 200 g | | Item model number | 1831023 | | Manufacturer | Wynn Oil UK | | Manufacturer Part Number | WY70612 | | Product Dimensions | 5 x 5 x 19 cm; 200 g | ## Product Details - **Brand:** Wynn's - **Item form:** Liquid - **Item weight:** 0.2 Kilograms - **Package information:** Pot - **Package weight:** 0.23 Kilograms ## Images ![1831023 70612A 250 ml Bleiersatz - Image 1](https://m.media-amazon.com/images/I/61XxhH31GML.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Z***O on 3 December 2025* Works really well and easy to dispense. ### ⭐⭐⭐⭐⭐ Review *by H***B on 21 April 2022* Een issue met de levering werd snel en netjes door de verkoper opgelost ### ⭐⭐⭐⭐⭐ Review *by J***B on 21 November 2025* produit impeccable , fait le travail , marque reconnue ## Frequently Bought Together - Wynn's Lead Substitute, 250 ml, 1831023 - Valvoline VR1 Racing SAE 10W-30 Motor Oil 1 QT, Case of 6 - Chevron Techron Concentrate Plus Fuel System Cleaner, 20 oz., Pack of 1 --- ## 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/358624759-1831023-70612a-250-ml-bleiersatz](https://www.desertcart.us/products/358624759-1831023-70612a-250-ml-bleiersatz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
