in the S4 forum about putting rocket fuel (Toluene?) in their cars. Anyone know anything or heard anything about this? Interesting..<ul><li><a href="https://www.audiworld.com/forum/m.new/s4/msgs/172633.phtml">https://www.audiworld.com/forum/m.new/s4/msgs/172633.phtml</a</li></ul>

I work in the chemical industry and use toluene often. It's extremely brutal on most rubbers, including natural, neoprene, viton, and Kalrez. Plus it's bad on your liver. Not sure what, if any, parts are composed of rubber in the fuel system.

Buy some rubber gloves and a pint of toluene from the hardware store and see for yourself. You can use the leftovers for paint remover. 'Cept the gloves however. They'll swell up and blister till they fall off your hands. Getting toluene on your skin isn't good either.

Believe it or not, but all the gas that everyone is using is basically the same thing from the same companies. The difference is the amount of toluene is added in(along with all the other mumbo, jumbo, like Textron).

The companies that sell octane boost, is basically toluene. But its a whole lot cheaper.

You can add about 1 to 2 gallons to your engine with/o risking cold start problems. It would boost your octane to about 96.
