Interesting to hear this about the 104 Octane booster. The article I
referenced
with regard to boosting the octane says that these additive cans only raise
the
octane 0.2 to 0.3 of an octane point. The mixture of Toluene that is
suggested
raises the number about 2.4 points.

Haven't seen anyone chime in on the mixture. Has nobody every used Toluene
or Xylene as a booster?
