Steve;

You are correct in using lacquer thinner (tulene) to up the octane. The post you are talking about is probbably mine but not at cobranet.

I used to be with a dirt track race team and we did mix about 8 to 10 ounces per gallon of 93 octane gas to get right at 100 octane.We bought the generic laquer thinner at the local Auto Zone for about 4 bucks a gallon and we used about 8 gallons or less of gas a nite,so a gallon of laquer thinner went a long way and was cheaper than 4 bucks a gallon for racing gas at the track.

There are other additives out there,some are good some are not,try them till you find one that works for your application.
