This is due to the improved burn characteristics of this gasoline when compared to conventional street gasoline. 100 Unleaded Racing Gasoline burns more efficiently (and therefore more completely). Another reason for the improvement in power is that the gasoline contains an oxygen compound. This is likely having higher barometric pressure which provides more oxygen. More oxygen means more horsepower. This is what it's all about. MORE POWER!
REDUCED EXHAUST EMISSIONS:
If your vehicle has failed an emissions test, 100 Unleaded Racing Gasoline may help you pass due to the improved combustion efficiency of this product when compared to conventional street gasoline.
If your engine has a knock sensor, acceleration performance will reduced when detonation (ping) is detected. Reducing spark timing reduces the engine's tendency to detonate (ping), but also reduces power. By stepping up to a higher octane gasoline, the acceleration ability can be restored because the spark timing is not compromised. Sometimes higher octane gasoline is necessary for more power.
IMPROVED FUEL ECONOMY:
If your vehicle has a knock sensor, spark timing is reduced when detonation (ping) is detected. Reducing spark timing reduces fuel economy. When switching to a higher octane gasoline in a situation where detonation has occured at part throttle, the engine can then operate with detonation, thereby improving fuel economy.
The hydrocarbons in this gasoline are selected for their ability to vaporize, combust, and efficiently convert chemical energy to horsepower. These characteristics result in an engine that runs smoother than it does on conventional street gasoline.
CONTAINS AN OXYGEN COMPOUND:
The oxygen compound used helps to improve combustion efficiency which leads to all of the above: More power, quicker acceleration, reduced exhaust emissions, and improved fuel economy.
