Liquid Octane boost suggestions!

[DAVID GAGNARD]

I have a chart somewhere that shows the mixing rates of different octanes......naturally,I can't find it right now.......
I never ran pure toluene and wouldn't recommend it,I used it to increase the octane of pump gas and if my memory is correct, one gallon to 5 gallons of 93 octane pump gas would give an octane rating of around 96.5.........

BTW: toluene is what the oil refineries use to adjust the octane of a batch of gas when it is made/tested.......

found the chart,here it is.......
this is for mixing one gallon of fuel on the left side of the chart with pump gas.......
