When to Use / Replace?
Usage Frequency: Add one 500ml bottle to your fuel tank every 3,000 kilometers or every third tank of fuel for best results. For vehicles with higher mileage or performance issues, use more frequently as needed.
Application: Simply pour the entire 500ml bottle into your diesel fuel tank. No special equipment or engine flushing required. The treatment works during normal driving as fuel circulates through the system.
Suitable For: All diesel engines, whether new or used, including modern common-rail injection systems and vehicles equipped with DPF technology.
Frequently Asked Questions
Q: How long does one bottle last?
A: One 500ml bottle treats up to 60 liters of diesel. Depending on your fuel tank size and driving habits, this typically lasts 2-4 weeks of normal driving. For best results, repeat treatment every 3,000 km or every third refill.
Q: Will this damage my DPF or emission systems?
A: No. Wynn's Formula Gold is specifically formulated to be harmless to all aftertreatment systems including diesel oxidation catalysts, DPF filters, and modern emission control equipment. It actually helps maintain DPF cleanliness by reducing soot buildup.
Q: Can I use this in a new diesel engine?
A: Yes. This treatment is recommended for both new and used diesel engines. New engines benefit from improved combustion efficiency and fuel system protection from the start, while used engines gain from deep cleaning of accumulated deposits.
