What the best gasoline mix to use?

Good point Meat.

This is a really complicated subject with a ton of views on what does and doesn't work. On the link I provided above "Mix your own booster" it says the first formula (Formula 1) is straight Toulene. It states a 30% mixture will increase octane from 92 to 98.6. Another site I saw indicated something like a 14 to 1 ratio, 14 gallons gas/one gallon Toulene only raises octane by about 1.5 points ie 92 to 93.5. I guess you could do the math to figure it out. Bear in mind the commercial stuff works out to be a REALLY expensive method, not to mention hard to find and add when your on the road. I tell ya, you gotta reduce the darn compression somehow, someway, this additive thing sucks.
