Why does VP use Motor Octane Numbers?
Motor octane more accurately represents a high performance or racing application. The motor octane machine runs at a higher RPM, hotter temperature, and more timing, thus putting more stress on the fuel. Do not be fooled by high research or average (R+M/2) octane numbers. How much Octane do I need? Only enough to stop preignition and/or detonation. Remember there are other important factors in power output than just octane. Octane is not the measure of the fuel’s power output, it is only a measure of its resistance to preignition and detonation in an octane engine. Is VP Racing Gasoline made the same every time? Yes, absolutely. For many people this is one of the most important qualities of our fuel. If there are any improvements in the fuel, we will inform you of the differences and what to expect from these differences. We realize fuel is one of the things a racer can’t check, so we feel very responsible for quality control. If you ever suspect you have a problem with our fuel we wil
