The cost of 100-octane fuel varies depending on location and brand. In 2015, a Porsche forum user noted that 100-octane race fuel was available at a gas station in their area for $8.99 per gallon, which was significantly more expensive than regular 87-octane fuel, which typically costs around half of that price. Sunoco 260 GT 100 Octane Race Fuel can be purchased online and shipped to select states, and Torco offers a similar product with local pickup available. The demand for premium gasoline, including high-octane fuel, has increased due to various factors, such as stricter fuel economy standards and the belief that it improves engine performance. However, it is important to note that not all vehicles require or benefit significantly from high-octane fuel, and the refining industry has faced challenges in keeping up with the demand.

Cost: $8.99 per gallon
100 octane fuel is a premium unleaded race fuel ideal for performance vehicles. It is street-legal and provides outstanding performance benefits in classic cars, street cars, muscle cars, street rods, motorcycles, and ATVs. It is also compatible with two-stroke synthetic and mineral-based engine oils.
The cost of 100 octane fuel is $8.99 per gallon. This is significantly more expensive than regular 87 octane fuel, which typically costs around half the price. For example, a gas station in Orlando charges $4.50 per gallon for 100 octane fuel, which is more than double the price of regular gas in Florida.
The high cost of 100 octane fuel is due to several factors, including the demand for premium gas as more car owners "treat themselves" to higher-octane fuel as pump prices drop. Additionally, more stringent fuel-economy standards have put turbocharged engines in many new cars, and these engines often require premium fuel for optimal performance and mileage. The refining industry has struggled to keep up with the demand, contributing to the high cost of 100 octane fuel.
While some drivers may be willing to pay the premium for the potential performance benefits, others may find it cost-prohibitive. It is important to note that not all vehicles require high-octane fuel, and filling up with 100 octane fuel may not provide significant improvements in performance or engine cleanliness for all cars.

Not street legal in California
100-octane fuel typically costs around $8 to $10 per gallon, though the exact price can vary depending on the brand and location. It is important to note that 100-octane fuel is not street legal in all areas, including California.
In California, Sunoco offers a product called SS 100, which is similar to their street-legal 100-octane fuel, Sunoco 260 GT. However, Sunoco 260 GT is not street legal in California due to the state's fuel regulations. California has stricter fuel standards than other states, and fuels must comply with CARB (California Air Resources Board) regulations.
California only offers 91 octane fuel at gas stations, which can be an issue for cars tuned for higher octanes. Some car owners in California choose to blend their pump gas with higher octane fuels, such as aviation fuel or race fuel, to meet the requirements of their vehicles. However, it is important to note that using the wrong type of fuel can damage a car's engine and emissions systems.
While 100-octane fuel may offer benefits for certain high-performance vehicles, it is not necessary or suitable for all cars. Running a vehicle on fuel with too high of an octane rating can lead to reduced performance and other issues. It is important for car owners to refer to their vehicle's specifications and consult with automotive professionals to determine the appropriate type of fuel for their specific car.

Safe for street engines
100 octane fuel is a street-legal fuel that can be used in classic cars, street cars, muscle cars, motorcycles, and ATVs. It is safe for street engines and can be purchased online or at select gas stations. However, it is important to note that it is not street legal in all places, such as California and other areas with CARB regulations.
Sunoco 260 GT 100 Octane Race Fuel is one example of a street-legal 100 octane fuel. It is oxygenated and provides outstanding performance benefits. It can be used in supercharged or turbocharged applications without harming catalytic converters or oxygen sensors. It is also compatible with two-stroke synthetic and mineral-based engine oils.
Some people choose to use 100 octane fuel in their vehicles because they believe it offers improved performance and a smoother engine. One person who used 100 octane fuel in their Miata noted a huge difference in the smoothness of their engine. However, others have questioned whether it is worth the high price, as it may not provide a significant enough benefit over lower octane fuels.
It is important to ensure that 100 octane fuel is safe for your specific vehicle and engine. Some engines may not be tuned to take advantage of the higher octane, and using it may not provide any noticeable benefits. Additionally, high octane fuels can be more susceptible to certain issues, such as the buildup of deposits in older, dirtier systems, which can then clog the fuel filter. Therefore, it is recommended to properly store 100 octane fuel in opaque, tightly sealed containers in areas with stable temperatures.

Improves performance in classic cars
The cost of 100 octane fuel varies depending on location and supplier. In the United States, 100 octane race fuel can be purchased online from Petroleum Service Company, with one user on a Porsche forum noting the price to be $8.99 per gallon. In Europe, 100 RON gasoline is available at almost every fuel station supplied by large companies such as Shell or Aral, which offer 100 RON gasoline under the names Shell V-Power and Aral Ultimate, respectively.
Now, let's discuss how 100 octane fuel can improve performance in classic cars:
Classic cars, especially those without modern engine management systems and knock sensors, can benefit from using higher octane fuel. A higher octane rating allows the fuel to withstand greater compression before detonating, reducing the risk of engine knocking or pinging, which can be detrimental to the engine's health.
Using 100 octane fuel in a classic car can provide several performance advantages. Firstly, it can increase the engine's power output, particularly in higher-compression gasoline engines. This is due to the engine's ability to compress the air-fuel mixture more effectively, resulting in higher power.
Secondly, 100 octane fuel can improve engine responsiveness and drivability. With a higher octane rating, the engine is less likely to experience pre-ignition or knocking, allowing for more precise ignition timing and throttle control. This can lead to smoother acceleration and a more responsive driving experience.
Additionally, 100 octane fuel can enhance fuel efficiency in classic cars. By reducing engine knocking, the fuel enables the engine to operate more efficiently, extracting more energy from each combustion cycle. This can lead to improved fuel economy, especially on the highway or during cruising.
It is important to note that the benefits of 100 octane fuel in classic cars may vary depending on the specific engine design and other factors such as maintenance history and the condition of the ignition system. While 100 octane fuel has the potential to improve performance, it is always recommended to consult a classic car specialist or mechanic before making any fuel changes to ensure compatibility and avoid potential engine issues.
