We blend Q16 fuel primarily for intercooled, forced-induction drag race applications. Many regard it as the top oxygenated, leaded fuel produced by VP. It is required to increase fuel flow by 4-6% because it’s highly oxygenated. Q16 make 3-5% more power than competitive 116 octane fuels, and the added fuel flow effectively increases the octane of the fuel by 6-8 numbers above its standard ASTM octane rating, resulting in greater detonation protection.
