I read the first paragraph and that was enough. Another big oil conspiracy theory. Where's the "100 MPG carburetor" we've been promised since the twenties? Well, GM and the oil companies bought the patent and buried it. We all know that!

I can tell you that acetone is a very powerful organic solvent and will attack nearly all organic materials. I would never, ever even remotely consider adding it to the fuel tanks of any of my cars.

There are a lot of organic materials in KE fuel systems. Check out the price of new pumps, accumulators, regulators, fuel distributors, etc.

You can look in any chemistry reference book and get the heating value of acetone and the cost of a gallon at the hardware store. Then compute the BTUs per dollar and compare it to a gallon of gasoline's 120,000 BTUs for about two bucks.

The bottom line is not miles per gallon, but miles per dollar of fuel cost.
