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.
