Wynns Petrol EGR Cleaner is a specialized aerosol product designed to clean and restore proper function to contaminated Exhaust Gas Recirculation (EGR) systems in gasoline engines. This professional-grade 200ml formula contains powerful solvents that rapidly dissolve carbon, gum, and varnish deposits that accumulate in the EGR valve, intake manifold, and throttle body, causing performance issues and triggering warning lights. The precision spray application allows targeted cleaning without requiring complete disassembly of components.
For best results, ensure the engine is at normal operating temperature then turn it off. Locate the EGR valve, throttle body, or other components to be cleaned. Where possible, disconnect the relevant electrical connectors. Spray liberally onto contaminated surfaces, allowing the product to penetrate deposits. For severely contaminated valves, spray in short bursts and allow the product to work for 2-3 minutes between applications. After cleaning, wipe away loosened deposits with a clean cloth where accessible. Reconnect any disconnected components and start the engine, allowing it to idle for 5-10 minutes before normal operation.
Petrol EGR Cleaner is particularly valuable for addressing common gasoline engine issues including rough idle, hesitation, stalling, and illuminated check engine lights related to EGR or throttle function. This product provides a cost-effective solution before considering expensive component replacement. For preventative maintenance, use every 10,000-15,000 miles, especially in high-mileage vehicles or those used primarily for short trips. For comprehensive intake system cleaning, consider combining with Wynns Xtreme Petrol Cleaner fuel treatment for complete system care.
