Octane booster, which is normally sold in plastic bottle or can form, is simply poured directly into a vehicle's fuel tank. Although octane booster can be added to a vehicle's fuel tank at any time, for best results it is advised that octane booster be added to an empty or near-empty fuel tank and then topped off with a full tank of gas.
Most octane boosters on the market raise gasoline octane between two to eight points. The higher the octane-raising effect of a particular octane booster, the greater the effect on engine combustion and vehicle performance. A typical octane booster will normally contain one of the following ingredients: glycerol, ethano, or methylpropanol. All of these ingredients are octane-enhancing chemicals.
Engine combustion, which is the burning of air and fuel inside an engine, is significantly improved with the addition of octane booster. As fuel containing octane booster enters a vehicle's cylinders, the spark from the spark plugs ignites the air/fuel mixture inside the engine. Due to the higher octane rating of the igniting engine fuel, the resulting explosion, or combustion, inside the engine is much greater; this results in more engine power and more efficient fuel burning.
A by-product of increased engine combustion is a decrease in engine emissions. The use of octane booster raises gasoline octane, which increases engine combustion and temperature; this increased temperature causes more of the fuel entering an engine to be burned in the higher combustion heat, instead of whole, unburned fuel being released through the vehicle exhaust system and exiting the tailpipe.
