I too, support the Acetone theories. I started with 1mL per gallon as my ratio and saw an immeadiate 4mpg improvement. Since then I have retained the ratio, applied other tips and my mileage keeps increasing. I am at a point now where I will stall mods for a couple of tank fulls just to mess with the acetone ratio to see what my vehicle is comfortable with.

I am also going to introduce it into the 4-runner in a couple of tank fulls to see what a baseline difference it makes.

Bottom line I see it working, whether my vehicles optimum ratio is 10mL per gallon or 30mL per gallon I will know for sure in a couple of weeks.

Having shows like Mythbusters support a theory like adding Acetone to gas is also a liability. While it may work, no one can predict any sort of long term damage due to poor maintenance, misuse, or the dumb public. Consider its corrosive properties if you get it on paint or even plastics for extended periods of time. So they most likely had to appease their public by addressing it, but skewed results to avoid larger problems down the line.
