Ethanol vs Non Ethanol Gas While Towing

I am on my 5th full tank of Non Ethanol Gas in My 01 Yukon and have seen a 2-4 Mpg increase in MPG! In town also it seems to start quicker and just over all Run Smoother than on the Popular gas everyone is Buying, I found a Station close to me that sell it on the Main Island at about $.25 more I was skeptical if it was legit at first but I found a way to test it! I use a Mason Jar and put about 3" of water in it then Mark the water level with a sharpie, put enough NE Gas in to double the volume, Cap Tightly and Shake, then let it separate, if the water level stays the same then there is no Ethanol in the Gas If Ethanol is present some water will have been absorbed into the Fuel like what Dry gas does, My Question for everyone about the non ethanol gas? has anyone used it while towing did they see any improvements over using the Ethanol Fuel? I should find out soon If I wind up towing my TT from NJ too SC I will try to use a App to locate NE selling stations on my route,

I guess this wont tell me much till I try the Ethanol fuel later?

    So we switched our corn production to fuel and then import food from Mexico! Go figure!

    Ethanol added to gas reduces the energy content of the fuel, so yes you should see better mileage


    I have seen an increase in MPG using non ethanol, but I am not sure about the energy difference. From what I have heard it has more octane thus allowing the ability for higher compression which in turn can result in more power. I am not talking about everyday use, but energy wise. I don't know if it is true because I read it on the internet.

    First there is no such thing as "more octane".
    Octane in this context is a measurement system and not a distinct thing.

    The lower energy content is a scientific fact. If you really care, look it up with a Google search and ignore postings in places like this in favor of scientific journals and text books.
