Frequently Asked Questions

Q: How often should I use this fuel system cleaner?
A: For optimal results, use one 325ml bottle every 3,000 km or at every third fuel refill. This maintains a clean fuel system and prevents deposit buildup. If your vehicle shows signs of rough running or poor fuel economy, you can use it more frequently.

Q: Is this product safe for my car's engine and emissions equipment?
A: Yes. WYNN'S Fuel System Cleaner is specifically formulated to be safe for catalytic converters, oxygen sensors, and turbochargers. It works with all petrol engine types and is compatible with modern gasoline blends including E10 and E15 ethanol fuels.

Q: Will this cleaner fix my rough idle and hesitation problems?
A: In most cases, yes. Rough idle and hesitation are commonly caused by fuel injector deposits and water in the fuel system. This cleaner removes those deposits and emulsifies water, often restoring smooth running within one tank of fuel. However, if problems persist after use, have your vehicle inspected by a mechanic as other issues may be present.
