    No doubt! We’re paying $3.15 average/ gal for “premium”, which at altitude is 91 octane. (Bastards!) E-85 is typically at $2.29.

    This time last year we were paying $1.80 for E85!

    The more alcohol content, the less the price should be. Ethanol is subsidized and should be less per gallon. That's why when the E85 price is close to the E10 price, I pass and get premium gas. Not enough ethanol in that expensive E"85" to be near what I want for ethanol content.

    I think if ethanol weren't subsidized, there'd be no ethanol!

    I think you are correct.

    I have seen various reports that say when it is all said and done, it takes 60-70% more energy to produce a gallon of ethanol than the amount of energy you get from it. It takes something like 130,000 btu’s of energy to produce a gallon of ethanol which only has about 80,000 btu’s of energy.

    Last I recall reading, it cost about $1.70 to make a gallon of ethanol vs about $1.00 to make a gallon of gas. With that math, a gallon of E10 would have cost roughly $1.07 to produce while a gallon of E85 would cost $1.60 to produce.

    Here is one article on the topic.

    The article assigns all the cost of harvesting corn to ethanol it seems. When the corn is processed, so much is used for ethanol, so much is used for this, so much for that, etc. There's also been a revolution in farming; when that article was written, farming methods yielded 328 gallons of ethanol per acre. In 2017 that number had risen to 507 gallons and that was three years ago. Last time we spoke on this subject, it was my understanding that Uncle Sam was no longer directly subsidizing the production of Ethanol but there was a legacy program from the previous administration and congress signed into law that gave grants to gas stations to install blender pumps and carry and sell E85 and other mixtures like E15/Unleaded 88.

    I like the stuff but it should stand or fall on its own merits, not be propped up by Uncle Sam.

    Does anyone know why GM isn't pushing Flex Fuel vehicles anymore? I can't a late model 6.2 anything that runs on corn anymore.

    Yep, the subsidies from Uncle Sam expired. Plus I reckon that lady who is running GM wants to get rid of all engines and go all electric.

    Six hour or so run in the truck today. Broke a world record; for this truck! 19.1 MPG @ 70 MPH over a 120 mile stretch of two roads. It just kept climbing and climbing a tenth every 5 miles. Of course, on the way back it just kept dropping and dropping which is odd as when you head northbound there is an ever so slight grade.

    Now, what's most unusual about this is that it was not on gasoline but a mixture of 8 gallons of E85 and 18 gallons of E15 for an alcohol content of 25%. I checked the alcohol content on the outbound leg but not on the return and we did shut the engine down for about an hour. Right after refueling a few weeks ago, the AC settled down to 26% and then the next time we drove the truck several days later it was 29%. Seems she went into relearn mode after every couple of days or maybe even after each ignition cycle?
