(2 pack) Gumout Octane Boost, 10 oz- 510022W

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. Keep your engine clean with the Gumout Octane Boost, 10 oz. Your engine needs good, quality gasoline to maintain the best fuel economy and good combustion. Fill your tank with gas and then add this product to maximize the performance of your vehicle every time you fill up. It will help prevent knocks, pings and power losses in your vehicle. This gasoline octane booster should be used with every fill-up for best results.
