The acetone update!

I didn't drive the entire trip with acetone in the gas tank. I only drove from my mother in law's house to work and back, then to a gas station where I filled the tank again. My original gas mileage was 12.89 MPG. Today I filled it up and the gas mileage is 13.41 MPG. A small improvement but an improvement nonetheless! I am going to add 2 more ounces and will report back on the next fill up.
