Default Toluene

Sorry if this has been asked before, but the search engines are down. I've been doing a lot of research on Toluene, but am still a little warry of pouring it into my gas tank. I live in California, so I can only get 91 octane gas without spending a fortune on 100 octane race gas. If I use 2 gallons of Toluene (114 octane) mixed with 12 gallons of 91, I should come out somewhere around 94.5.

Does anyone have any first hand experience with this? Or xylene?

Yes, lots of people are using toluene. I have heard that xylene is harder on rubber than toluene, but have no firsthand experience to support this.

Here's a thread for you:

Default works good

Either xylene or toluene work just fine. Toluene is frequently 20% - 30% of the blending stock in high octane fuels so putting a little more in the tank is basically what happens with the high perfomance fuels anyway. The refiners generally hold xylene content down to much lower levels, probably because it has a much higher boiling point than toluene.

There are quite a few of us who have used anywhere from 1 :4 to 1 : 6 blends of toluene and or xylene in 91 premium to get a little better octane profile.

In some areas of the country toluene is very tough to get, and thats the main reason many of us use xylene. It is just easier to source.

We use Tolulene in our homemeade traction compound for our go-kart tires, and it REALLY softens them up. Xylene doesn't seem to work as well. Of course we also mix it with lacquer thinner and ATF, so that may or may not mean anything.......
