GUMOUT fuel additive 296 ml

All engines are calibrated to operate on fuel with a specific octane rating. If the octane is too low, the fuel may ignite early, causing knocking and noises. In vehicles with knock sensors, low-octane gas can delay timing, reducing performance and fuel economy. Octane booster from Jumot raises the octane level in the gas to restore proper combustion and performance. Add the entire bottle to an almost empty fuel tank, then fill the tank with up to 15 gallons of gasoline. Use for full filling.
