Fuel Doctor is designed to enhance the performance and longevity of your vehicle's fuel system, so the frequency of use can depend on various factors such as driving habits and vehicle type. Generally, many users find that using Fuel Doctor with every fuel fill-up yields the best results, particularly if they drive frequently or in conditions where fuel quality may vary. However, for those who drive less or are using premium fuels, using it every few fill-ups may still be beneficial without being excessive. It is important to consult the specific instructions provided on the product label for the most accurate recommendations tailored to your situation. Additionally, it can be helpful to monitor your vehicle's performance and fuel efficiency over time to adjust the usage frequency as needed.
