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.
