, I was getting ready to make a comment but you beat me to it. I wonder if we should confuse them now with specific weight gravity of fuels and how that effect the total flow numbers and flame propagation?

OP, don't waste the money on the race gas unless you know you have knock. Spend the money on a good gauge or scan tool to measure knock.
