UPDATE:

This is with conventional gas and 4 oz of Acetone. Obvious improvements but not enough. I would like to see in the 360s or so. But my tank and computer still need seasoning so I think by the 5th tank I will have my best output yet. I am currently on my fourth tank. This 345 is with some of the worse traffic yet calculated in it. It is Derby week around here for those of you that are familiar with the best 2 minutes in sports and this week = horrible traffic. I was in bumper to bumper for over an hour two days this week.

This came from 20.06 gallons of gas. =17.25 quite and improvement over my almost 10 mpg a year ago.
