Q: Does it matter what grade of petrol I use? A: No, Prolong fuel additives are compatible with all grades of petrol. Q: How often should the fuel additives be used? A: Use the Fuel System Cleaner every 3,000 miles. Use the Injector Cleaner in between if you detect fouling, poor firing or starts, or reduced mileage. Q: What is the advantage of the Prolong Octane Boost? A: The Prolong Octane Boost provides a street-legal increase in octane power, even at the highest pump level. It provides extra power and performance that may not be needed all the time, such as pulling a boat or trailer, especially over steep grades. Q: Why is it important to use the Prolong Fuel System Cleaner or Fuel Injector Cleaner? A: Over time, carbon deposits and sludge build up in the fuel lines, carburetor and injectors, robbing your vehicle of power and causing poor fuel economy. The Prolong Fuel System Cleaner removes and even helps prevent this build-up from occurring. It also adds lubricity to the fuel to help protect gaskets and seals and optimize mileage. The Prolong Fuel Injector Cleaner removes deposits on injector tips and maximizes the fuel spray pattern for peak performance and fuel economy. | ||||||
