octane booster

[dzorde at aesprodata.com.au]

     We have successfully used Toluene in a mix of 1L for 5L of 96 octane 
     leaded fuel, also gives you beautiful flames out the back and that 
     nice crisp popping sound when you back off.  But to find out if it is 
     an octane problem, get a tank of avgas (100 octane) if this doesn't 
     fix the problem, its not an octane problem.  However, if it does fix 
     it, it is definitely cheaper to buy Toluene and mix your own.

Hi guys. I *think* I am running out of octane in my BMW 530i - I have high 
compression pistons, and the car is choking at high rpms. Have checked most of 
the obvious things like fuel pressure, filter, etc.
     
I read here that xylene or Toluene is the way to get more octane. How much 
should one add to each tank?
     
What is the minimum octane I would need with 9.5:1 pistons?
     
Thanks in advance.
