Not Ranked
It's not a waste of money if it stops dieseling or run on problems, I can attest to this. Look,- good octane booster like Klotz or a Toluene works, if your car is on the edge. Race gas in a 50/50 mix is far better especially if you are way over the edge like Ron said. 11.5:1 is not on the edge. My 10.75:1 on a hot day is,.. and I have used a quality octane booster and/or Toluene to correct some minor issues.
Ron, what kind of fuel did you buy and where did you get it?
