Racing fuel ranges from 100 to 120 octane
Racing fuel is a type of gasoline designed specifically for high-performance engines in racing vehicles. It contains more additives than regular fuel, such as ethanol, methanol, and lead, which boost its octane level and improve performance and fuel stability. The octane level of racing fuel typically ranges from 100 to 120, significantly higher than the gasoline at a typical gas station, which usually ranges from 87 to 93 octane.
The higher octane rating of racing fuel makes it more resistant to detonation and prevents pre-ignition, also known as "knocking." This is particularly important for racing engines, which operate with higher compression ratios and require higher-octane fuel to function properly. The use of racing fuel in street vehicles is not recommended as it may result in a loss of efficiency and potential damage to catalytic converters and oxygen sensors.
Several companies specialize in providing racing fuel, including VP Racing Fuels, ETS Racing Fuels, and BOOSTane. VP Racing Fuels offers over 70 proprietary blends of leaded and unleaded race fuel, and has powered numerous racing champions worldwide. ETS Racing Fuels are known for their consistency and performance, with fuels designed for both vintage vehicles and turbocharged engines. BOOSTane's 110+ octane leaded race fuel is a versatile option suitable for various racing applications, burning cooler and cleaner than other 110 racing fuels.
The price of racing fuel can vary depending on the brand, octane level, and quantity purchased. For example, Sunoco Race Fuels offer 118 Octane Leaded Race Fuel, which is priced between $118.49 and $805.95, depending on the amount bought. Race Gas Ultra, when mixed with pump gasoline, can create racing fuel with an octane level between 108 and 112, providing a cost-effective alternative for high-compression engines.

High octane fuel requires a hotter spark to ignite
The octane rating of a fuel is a measure of its ability to resist autoignition. The higher the octane rating, the more resistant the fuel is to autoignition. This means that higher-octane fuels require a stronger ignition source, i.e. a hotter spark, to ignite.
Higher-octane fuels are used in high-compression engines. These engines are designed to compress the air/fuel mixture to a greater degree, which requires a higher-octane fuel that can withstand the higher pressure without autoigniting. The higher compression ratio results in higher cylinder pressures, which in turn deliver greater power.
However, using a higher-octane fuel than is recommended for an engine does not improve performance. Engines are designed to burn fuel in a controlled manner, with the spark plug creating a flame front that spreads evenly across the cylinder. If the octane rating is too low for the engine, the fuel may ignite spontaneously due to the higher temperatures and pressures, causing an uncontrolled secondary combustion known as "knocking". This uncontrolled combustion can cause damage and place high pressure on the engine components.
On the other hand, using a higher-octane fuel than is necessary can also lead to incomplete combustion and carbon buildup. This is because the higher-octane fuel requires a hotter spark and higher pressure to fully combust, which may not be provided by the engine. As a result, there may be unburnt fuel in each charge, which can smolder and burn less cleanly.
In summary, high-octane fuels require a hotter spark to ignite due to their increased resistance to autoignition. This property makes them suitable for use in high-compression engines, where the fuel must be able to withstand higher pressures without spontaneously combusting. However, using the correct octane fuel for the specific engine design is crucial to ensure optimal performance and prevent engine damage.

Racing fuel may damage catalytic converters and oxygen sensors in street vehicles
Racing fuel is not the same as the fuel used in street vehicles. The main difference is in the octane level—street vehicles typically use fuel ranging from 87 to 93 octane, while racing fuel ranges from 100 to 120 octane. The higher octane level in racing fuel makes it more resistant to detonation and prevents pre-ignition, also known as knocking. However, using racing fuel in a street vehicle may result in a loss of efficiency because it requires a hotter spark to ignite.
Additionally, racing fuel may contain extra additives such as ethanol, methanol, and lead. Leaded gasoline was phased out for street vehicles between 1986 and 1996 due to the Clean Air Act but is still used in limited capacities in racing fuels, aircraft fuels, farm vehicles, and marine vessels. The lead in leaded racing fuel can coat the sensors and catalyst metals in the catalytic converter, reducing its efficiency over time. This can affect engine fueling as the engine controller will adjust fueling to provide more oxygen for the converters to absorb.
The use of leaded racing fuel has been associated with the failure of catalytic converters and oxygen sensors. The lead in the fuel can attach itself to the catalytic metals, reducing their ability to process exhaust gas. This can lead to increased fuel consumption and engine performance problems such as sputtering and surging.
Furthermore, a malfunctioning oxygen sensor can also damage the catalytic converter. When the oxygen sensor malfunctions, it sends incorrect data to the vehicle's main computer chip, which increases the amount of fuel in the combustion chamber. The extra hydrocarbons from the excess fuel can clog and damage the catalytic converter, resulting in black exhaust smoke and a failure to pass emissions tests.

Octane boosters increase octane but not chemical energy
Octane boosters are fuel additives that blend directly into a vehicle's gas tank to increase the octane rating of the fuel. They are designed to blend with pump fuel to raise the effective octane of the fuel above what is possible to purchase from a gas station. BOOSTane, for example, can boost pump petrol by between 2 and 3 octane numbers.
Octane boosters are often used by car enthusiasts to improve the performance of their engines. They are particularly useful for engines that require more octane than what is available at the pump or if race fuel is unavailable or too expensive.
It is important to note, however, that octane boosters do not increase the chemical energy of the fuel. Octane boosters contain hydrocarbons that are harder to ignite than gasoline. Aromatic compounds, which are commonly found in octane boosters, are lower-energy fuels that do not burn as readily. The goal of an octane booster is to moderate combustion, not make it easier.
While octane boosters can improve engine performance and add horsepower, they do not increase the amount of energy in the fuel. This is a common misconception. In fact, using racing fuel, which has a higher octane rating, in a street vehicle may result in a loss of efficiency because it requires a hotter spark to ignite. Therefore, while octane boosters can increase octane ratings, they do not increase chemical energy.
