Easy way to make Cali 91 Octane into 95?

I have heard that the ecu will adjust timing, etc up to 95 octane.

I am living in the wonderful state of California where we have 91 octane. 100 octane isn't readily accessible to where I live.

What is the next best way to raise the cali 91 octane up to 95? Toulene? if so, what ratio should i use w/ 91 octane? any negative side effects?

thx.

like u, im in the bay area. i found toluene but it is too cost prohibitive for the amounts needed. race gas would be the solution but vp in san leandro is hella expensive compared to almaden 76 in sj (which is too far). lol.

If I remember, a gallon is $250.00, a little less, treats 782 gallons of gas.
