    Gotta love ethanol free gas

    4 straight tanks in Michigan's UP and 47.3, 48.2, 49.3 and 48.0 mpg. Wish we could get ethanol free in IL

    When I use E-Free racing fuel to put some engines to bed for the winter, I find, the aroma of the "old fuel" like a trip back in time.

    I have ran ethanol free gas in my bike, car and truck to test against gas with ethanol. After running about three tanks through all of my vehicles I came to the conclusion that despite what most claim the gas mileage improvement was so minimal to not be worth the extra cost. They do charge more for ethanol free gas at the station I am able to purchase at. I do purchase and run the ethanol free gas in all my small engines and will fill my bike with it for winter storage but outside of that it's really all hype in my humble opinion and experience. It's not a game changer in MPG and there was no noticeable H.P. difference that I could detect on a normal day of riding.

    I would not use ethanol free out of concern for mileage or performance but because of other technical problems that ethanol brings, i.e.: fuel stability, corrosion and adverse effects on certain materials in the fuel supply system. For this, I gladly pay a little more.

    I know I'm interloping here with you K guys but on my 2011 R1200GS I do see noticeable improvements with mileage. Near my home I can get 87 and 93 octane ethanol free. I run the 93 which is about $3.99 per gal and my mid-grade E10 is about $3.40. Mileage on my instrument panel is 44-46 with E10 and 48 with E0. Gulf is selling 89 octane mid grade in NC for exactly the same price as E0 mid grade and it give me 49-50 mpg. The bike doesn't go any faster, but idle is smoother and transitions out of corners are also smoother. This data comes from multiple tanks and doing the fill amount / miles driven method has always been real close to my instrument panel.

    For years I had no choice but to run the gas with the ethanol and have had absolutely nothing go wrong with any of my vehicles. I do think it could make a difference on older small engines or older verhicles developed long before ethanol came into existence. I will go out of my way to ensure I only use the ethanol free gas in any of my older engines such as a lawnmower or chainsaw engine but for any newer vehicle I seriously doubt it makes any difference at all. Just think of how busy all the auto repair places would be if ethanol were truly that bad for engines and the lawsuits would be unstoppable.

    RECENT MODERN cages may not be much of an issue with ethanol other than those that come from water separated fuel in badly managed filling stations but it sure creates problem is small engines.
    Take some time to talk to your local small engine repair place and ask them how much business has been created for them since this junk replaced pure gas. Almost all of it gummed carbs (in fairness, also possible with pure gas), some of it non-compatible parts damaged by ethanol. My local folks say its half of their business.
    If you add up all the costs associated with ethanol use, its pretty obvious its basically a subsidy to large farm industry and wastes a food crop doing it.
    Our energy security from foreign oil isn't going to come from ethanol in any appreciable way but instead from our own natural gas sources, whatever we can get from renewable stuff, etc.

    I see a good 4-5mpg difference when I'm out of state and can burn pure gas. Track stuff pretty religiously. YMMV (literally. )

    Wow Chuck, you are one lucky son-of-a-gun! Ethanol in my area has been and continues to be an absolute nightmare. It is hard on everything from fuel injectors to fuel tanks. Last fall I went to give my snowblower, that is only two years old, a checkup before winter. I forgot that I had put a small amount of ethanol gasoline in it before putting it away and I did not drain/run it out of the blower before putting it up for the summer. Long story short the inside carburetor looked like some kind of fungus from another planet took it over. I have never seen anything like it in my life. There is a definite difference in almost every vehicle I own when I am forced to use gasoline blended with ethanol. I am glad you are happy with the stuff but it is garbage from first hand experience. I almost never use it in my motorcycles unless I have no choice and then it is just enough to get me to some real gasoline.

    YMMV is so true...

    I've always been somewhat fanatical about tracking gas mileage in all our vehicles. When our local Chevron station started serving up ethanol I noticed the difference quickly with my bike, car, and truck. And of course they NEVER tell you how much ethanol is in the blend, just a small note on the pump that states "this fuel MAY contain up to 10% Ethanol". Sort of a crap shoot, to say the least! So, I buy their gas most of the time, and notice the difference in our '07 Avalon. With EO we average 26+ in mixed use, 31+ in freeway cruise (65-70mph), mpg drops 10% in both driving modes with E10 (E?) in 90K miles of driving experience. I'm a big fan of Techron (198K on our F-150) and will continue using Chevron/Texaco most of the time. We do use E0 from another station now and then, the 10% improvement in mileage is worth the extra 3% in per gallon cost.

    As they say...YMMV!

    Cheers!

    I dare to say that some newer vehicles and associated technology - like fuel pumps and level sender strips in the tanks - have more problems with ethanol than older, simpler designs. The fact that gasoline gums up in small engine carbs is not an engine problem. It is a maintenance problem and can be addressed by adding stabilizer to the gas. I do this on my lawnmowers, snowblower, chainsaw and weedwacker and never had a problem. They all start up and run even after 6 months of sitting in the shed.

    Ethanol in gas

    The small engine repair person that fixes my lawn mower tells me fuel problems associated with ethanol problems is epidemic. Foolishly we modeled our ethanol program after Brazil who makes their ethanol from sugar cane witch produces seven times the production of corn.At the end of the day this policy will go down as one of the least efficient way to make us energy independent.
