    New study: 20% ethanol does not harm current vehicles

    Minnesota Study Finds E20 Passes Materials Compatibility and Driving Performance Tests
    5 March 2008
    Increasing the amount of ethanol blended into gasoline from 10% (E10) to 20% (E20) does not present problems for materials used in current vehicles or fuel dispensing equipment and provides similar power and performance, according to a new study released Wednesday by the State of Minnesota.

    This initial scoping study for E20 consists of three main areas of investigation: materials compatibility, drivability, and emissions. The emission testing is still ongoing and the results will be released as soon as the testing is complete.
    ...
    Key findings of the report include:

    The effects of 20% ethanol blended fuels do not present problems for current automotive or fuel dispensing equipment.

    The drivability study showed that E20 provided similar power and performance to E10 ethanol blended fuel throughout the entire calendar year, which included a broad range of ambient weather conditions.

    Based on the materials compatibility and drivability testing results of this scoping report, there are no issues that would prevent moving forward with the comprehensive testing required to certify E20 as a federally approved motor fuel.

    Re: New study: 20% ethanol does not harm current vehicles

    This is great news. I think its more practical to ease into E85, than it is to just dump it onto consumers. Heck if you started with all gasoline being E5, then moving to E10,E15, and E20. I don't think most people would pay enough attention to realize the sticker on the pump indicating the ethanol content.

    Once we reached, or expected to reach, a level of ethanol that could not run in a standard ICE, manufacturers would be expected/required to make all of their new engines compatible with higher percentages of ethanol. This would also allow engine builders to design the engines for ethanol, thus making them more efficient.

    I know I'm not taking into account a ton of different variables, but I like my pipe dreams just the way they are.

    I don't like this for 2 reasons.

    #1 With the exception of 1 study I read, all other evidence points to getting lower fuel economy with the more ethanol that is used in gasoline.

    #2 The study comes from the state of Minnesota...I'm guessing a midwestern state with a lot of corn that has something to gain by pushing ethanol.

    I reminber reading that 20% was too high. However, I reminber reading that 15% could work. One of the big oil co was working on 15%.

    I have an awesome idea.........

    instead of that 35MPG law if I were President I would banish it and instead force all gas to be first E10 then in 2-3 years go to E20.

    I don't think there is a straight decline in mileage as ethanol increases. I am pretty sure that the drop in mileage is pretty minimal going from 10% to 20%.

    I'd rather get lower fuel economy by supporting Minnesota corn growers than hand my money over to the oil companies and the Middle East. Besides, I bet a lot of your "other evidence" comes from less than squeaky clean sources (Big Oil).

    1. My own experience in two vehicles using E10/15 over four or five tanks indicates a consistent 10% drop in MPG. One of them had vastly reduced power, to the point it couldn't pull 60 MPH on some hills.

    2. I'm guessing you're correct. I would suspect this study, like many published reports these days, has its own agenda and that agenda = +$$+.

    I Have a blazer and Have gotten nearly 24 MPG on a trip driving 80 mph on 94, not a problem running E10 when it comes to power and fuel economy. I have never had problems with hill or fuel economy. Maybe you should buy a car with more torque to get up a hill.

    I am excited to use E20 vs. E10. If you think about it you will be saving more octane, but burning more corn which can be grown and replaced.

    What about everything else I use gas in? Boats, ATV's, snowmobiles, lawnmowers, etc... are they going to make sure it doesn't harm them too?

    No need to. Just make sure to buy your fuel for your boat and ATV at a Caliphate Gas Station: 100% gasoline, guaranteed, and explosive performance too!

    Re: New study: 20% ethanol does not harm current vehicles

    I remember reading another study showing that most vehicles could acutally jump to 30%-40% with no harm and acutally not loose fuel economy. I've ran E85 in our work cars. The differance is actually small. If you are loosing power on E10, you have bigger problems than running E10..... I saw about a 2-3 mpg decrease and the cost was about 30cents cheaper per gallon. It was a good wash IMO.

    I'm all for it.

    Exactly. Im not so bad off that 10% worse fuel economy will screw me. Most people could make that up if they changed their air filter, fuel filter and put air in their tires, let alone changed daily driving habits.

    I just hope high octane fuel stays as corn free as possible. I dont think my bike would like a change in its diet, and neither would I.
