STP Emissions Reducer Fuel System Cleaner is a pre-emissions test treatment formulated to lower emissions by removing deposits from the entire fuel system and clean components that affect emissions.
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.
sed as an additive in the fuel of all 2-stroke and 4- stroke gasoline engines, especially for motor vehicle engines. Also can be used in two-wheeled vehicles. For the improvement of vehicle acceleration and smooth operation.
