Offering substantial power gains at a competitive price, VP113 is oxygenated to street gas levels. Formulated for naturally aspirated engines with CRs up to approximately 14:1. VP113 makes up to 2% more power than competitive 110 octane fuels, with gains of 3-4% in engine applications with poor or marginal fuel vaporization qualities. VP113 burns cooler, ensuring power is maintained throughout the longest races and harshest conditions. May require a tuning change, including increase in jet size for optimum performance.
