Is ethanol gasoline good for the environment or causing you to fill up more often?

Ethanol is consider a biofuel alternative to gasoline.  It is produced from the fermentation of sugar from foods such as corn, sugar cane, etc. and it also can be produced by the hydration of ethylene from petroleum production too.  Many gas stations advertise ethanol additives in their gasolines and that by purchasing their ethanol gasolines you are helping reduce pollution in the environment, that your car will run better, etc.  Is this true and what are the things you may want to know…

Not all vehicles do well with ethanol based fuel.  Your gas mileage could be reduced and unknowingly you could be filling up more often. People who have reported reduced gas mileage with ethanol based gasoline are some hybrid owners and people with older cars. 

Of course for you to know whether ethanol based gasoline is affecting your gas mileage or not, you will have to test your own vehicle for results.

    A group of our friends tested this out with all our vehicles.

    Cars built after 2005 didn’t seem to have any gas mileage problems with ethanol based gasoline, but cars that were from the 90’s or older restored classic cars the gas mileage dropped considerably.

    Have you tried this? What were the results?

    You don’t know how to make your car run on ethanol PROPERLY. Let’s fix that: preheat the ethanol. Advance the timing. The comments about 90s cars are amateurish. My 1989 Ford with a 2.9 V-6 gets 90% of the mileage of gasoline,and I pay less at the pump. And my engine is going to last three times longer. And I change my oil half as often. And my emissions are so close to zero, the smog tech can’t believe his smog machine. And my ethanol adds ZERO CO2 to the air, unlike these dumb-ass electric cars. And we aren’t spending three trillion dollars to kill 1.2 million people for their ethanol. And the money I spend on ethanol fuel goes to farmers, not oil companies. And that money stays in North America instead of going to the middle east, where some of it winds up in the hands of a billion people who hate us and want to kill us because we just murdered 1.2 million of them for their OIL!
    You know, maybe there’s more to life than our own selfishness.
    The book that will show you how to succeed instead of fail is called:
    “Alcohol Can Be A Gas!” I succeeded with this book. You lot have failed without it.

    Perhaps your generalizing me and a group of friends that tested our cars for gas mileage with and without ethanol gasoline.

    Out of 10 cars tested only two noticed the difference in gas mileage. Not sure how that makes our whole group or myself amateurish or selfish. Not everyone is mechanically inclined or knows what effects their gas mileage or how to improve their gas mileage. That is why we have blogs.

    You seem to be a nice guy,and are at least honorable enough to not censor my criticism. Good on ‘Ya!
    However, the term “amateurish” is fair, because you did not convert your engines like an ethanol professional…and you just said you’re not professional mechanics. When you’re not a professional, you’re the quintessence of an amateur. Did you do the three things I told you to do?

    Whoops…two things,not three. The third thing is to change your fuel filter after a few tanksful of ethanol.

    Thank you for the info. I never considered that my old 1980 beater could be getting lousy mileage due to ethanol fuel.

    Eco-boy must of thought you were a guy and knew everything about cars and how to fix them. I doubt he would talk to his own mother, sister, aunt, etc. like that.

    btw my husband doesn’t know much about cars, goes on car repair blogs and doesn’t have anyone go off on him for what he does and doesn’t know.

    I’m not a nice guy, because I’m a she.

    Final comments, I have to get back to real life.

    Cheryl has misread Coco’s original posting and needs to re-read it.

    The Nice Guy Club has always welcomed nice guys of both sexes (unfortunately, so has the Bad Guy Club.)
    I am troubled to see any person, of any opinion, trying to become good at anything by using blogs.
    Instead, find out who is smart and successful at a particular form of endeavor, and get a deep understanding about doing that thing from that person.

    That means reading books written by those experts, not blogging with other people who are not experts.

    I bothered to tell you which book to read in order to succeed with ethanol fuel because oil addiction has brought us to the brink of Armageddon. I think you should read it. You will get much better miles per gallon, your engine will run a lot better in a Canadian winter, and you will be the only kid on your block who is not destroying what little remains of the whole miserable world. Believe it or not, I wish you well.

    Hello in there, Eco-Boy.

    You obviously have far more free time than the rest of us. Perhaps a job would help.

    Moving out of your mother’s basement could do wonders as well. Maybe meet some girls, things like that.
