Perry,
I agree 100% that Toluene is the major ingredient that is used to raise the octane in gasoline. I am pretty sure that it is not the sole ingredient added.
If you read the end of the article you would have seen the formula that a popular octane boost products manufacturer uses. Tolune, mineral spirits, & transmission fluid.
I do not understand your statement that i was wrong about the race gas being cheaper?
Toluene is $23 divided by 5 gallon is $4.60
Race Gas is $4.55 per gallon.
The cost of the 93 pump gas has nothing to do with the cost equation, as it is used in both cases.
If you add the other ingredients as is suggested the toluene cost will go even more than the $.05 you started with.
Another home made mixture I have seen used is 1 gal toluene + 1 qt mineral spirits+ 4 oz Marvel Mystery
Oil.
The one plus toluene has over race gas is 114 Vs. 100 or 112.
Last but not least is the "Safety Issue". If you read the Warning Label, it states that when handling toluene that you use a Vapor-particulate respirator (NIOSH approved).
For the record, I am not tring to break your b*lls. I am in the Fire Supression Business and have seen first hand Toluene Fires. It is Dangerious stuff. About the best way to extinguish it is using A FFF Foam in a 3% concentration applied on top of it.
I would just hate to see a flock of our members run out and start playing with toluene, not knowing all the facts. Hell the Race gas is lethal enough!
