The more an engine is driven, the more carbon deposits can build up on fuel injectors, intake valves and ports. Gumout High Mileage Fuel Injector Cleaner is specially designed to remove carbon deposits from engines with over 75,000 miles for restored engine performance and fuel economy.
All engines are calibrated to run on fuel with a specific octane rating. If the octane is too low, fuel can ignite early, causing knocks and pings. In vehicles with knock sensors, lower octane gas can retard timing, reducing performance and fuel economy. Gumout Octane Booster raises the octane level in gas to restore proper combustion and performance.
