as im sure you know, the higher the octane, the slower the fuel burns, this prevents knock, and gives you a longer flame for more power

octane booster basically is a flame retardant that will make the combustion less powerful, while increasing the burn time as i understand it.

plus the crap costs $5 and only raises your octane level one point, meaning you would need to use about 10 bottles of it to raise 90 to “100” octane in 15 gallons of fuel
