I'd almost rather just drive the extra 20 miles to get 100 octane at the pump than worry about handling toluene (and paying the extra cost). I did the math and it comes out to be about even if I have to pay $9.50/gal for toluene (20% discount) and add 2 gallons per tank of gas to get 94 octane versus filling up with 5 gallons of 100 octane (rest 91) and driving the extra 20 miles each way (~ 20mpg commute). Each would give me about 93.7 octane (which we all know really isn't "93.7" because craptane isn't really 91...but that's a different story).

I realize craptane sucks, but if it's all that's available?

I will not let my car be a slave higher, typically unavailable fuels.

IMO of course.

When visiting San Jose I'd like to know where to get my octane fix. I also use toluene but only 1 gallon per tank.

xylene is up to 15.xx at homedepot and lowes

I hit the 76 station on Woodside Rd. in Redwood City. I haven't been in a while. Last was $4.99/gal.

with higher octane I can have timing at 0 and let the ECU adapt...and potentially run higher boost too. True, I could keep the boost down but that's no fun.

I'm sure adding that to the tank will yield better results! But the race gas station is 10mi away.

If it's still $4.99/gallon of 100 octane I'd almost be tempted to fill up with that exclusively. Super unleaded where I'm at is $3.49/gallon.

Yeah, not to mention avoiding the health risks associated with handling the aromatics.

If 32 oz of torco raises octane so much (see al's post above), why can't you use half a can of it? That would be $10..
