Want to make a gallon of some AWSOME octane booster,, here you go... 100 oz of TOULENE ( found at home depot or a paint supply store).. You could use XYLENE or MTBE,, but " tolly" is easily accessible.... 25 ounces of MINERAL SPIRITS ( diesel fuel or kerosene will work just as well) and THREE OUNCES of AUTOMATIC TRANSMISSION FLUID.... Synthetic trans fluid is preferred,, but type "A" will even suffice... It will probably cost you around THREE DOLLARS TO FOUR DOLLARS for all these ingredients,,, BUY,, you can sell 16 ounce cans of this stuff to your buddies for FIVE OR SIX DOLLARS a 16 ounce can.... NO PLASTIC BOTTLES by the way.. STEEL or TIN CANS.... Keep away from ALUMINUM TOO !!!! Somewheres around 114 octane at up to 5%
