Johnny,
I am not calling you a liar, but would you like to see my fuel logs of years ago when I was still recording the amount of Eoh in each fuel purchase the resulting burn of that fill?
In the case of my coach, it was just about mathematical that the non-alcohol part was all that contributed to pulling Chaumière down the road. This came very close to agreeing with what we found a Michigan Automotive Research early in the "Gasohol" days.
I will admit that this does go contrary to what should be as far as stoichiometric flame chemistry, when I went to publish an SAE paper on the subject, I was slapped down and no explanation was forthcoming.
We did find at that time, that one had to mis-tune the test engines to get cleaner exhaust with the "gasohol" as fuel. There was also a corresponding reduction in performance with said mis-tune.
