For years, the amount of horsepower produced with "pump gas" has been a measuring stick for determining the overall badness of a street car. We've explained the inferiority of California's and Arizona's 91-octane fuel to the 93 octane of other states, and celebrated occasions where 93-octane power is achieved with the lesser fuel. VP Racing Fuel now offers its VP100 fuel at pumps throughout the country. VP100 (formerly known as StreetBlaze 100) is a 100-octane unleaded gasoline specifically engineered for high-performance street vehicles. As we saw on the dyno, the VP100 produced nearly 10 percent more horsepower than the 91-octane unleaded gas made. Since the VP fuel is oxygenated with ethanol, it's totally CARB legal and can be used anywhere. We feed our project Mustangs from a 55-gallon barrel of VP100, but you can look on the company's website to locate a gas station where you can fill up at the pump.
