Q16 REGQ16 Reg is primarily used in intercooled forced induction drag race applications and is often regarded as the best oxygenated leaded fuel VP produces. Highly oxygenated requiring a 4 6% increase in fuel flow which will make 3 5% more power than competitive 116 octane fuels. The added fuel flow also effectively increases the octane of Q16 Reg by 6 8 numbers above its standard ASTM octane rating yielding greater detonation protection. Its also used in
