10% toluene mix with 91 octane

i've recently tried an experiment with 10% toluene and 90% 91 octane... the 380se runs MUCH smoother at idle, and doesn't vibrate until i hit the mid 4k's.
it used to vibrate when i reached over 3.5k rpm. (the mix creates about a 94-95 octane)

at the moment, it's costing me $15 for 1 gallon of toluene... does anyone know where i can get it for less?? i've looked at ace hardware, osh, lowes, home depot... only sherman-williams has it.

i love the better performance, but i think i won't be able to afford $50 for 1/2 tank for long!

For my SEL/SEC Euro cars under high-compression, I just use octane booster from Torco (www.torco.com). It's good stuff, not the crap in the auto parts stores, and much safer.

Enjoy!
Bruce:
Do you mix the torco with regular or premium? Seems if you added it to premium you would go beyond the 94 octane.
