    E15 is OK now

    There's been a lot written about how E15 will slag our bikes, and how any left in the hose will dissolve delicate parts, etc. etc. Well, it appears that BMW has solved two problems with one stroke: E15 and sales growth. Look what it says in the owners' manual for my new R1250 GSA:

    The E5 and E10 in circles are British and mean what you think. How BMW has persuaded themselves that "E5" with 15% ethanol is an actual thing I have no idea but the bottom line is they're saying that what we on this side of the pond call "E15" is OK to use.

    So everybody go out and buy a new bike!

    Sometimes the BMW Riders Manual has some strange conversions or translations.
    Has anyone in the US ever seen 90 AKI gas?

    Around here we get 87, 89, and 91 - sometimes 93 or 94 as well. I always used 89 in my wethead, which is what the owner's manual asked for. At least at sea level. Whatever the middle button is. Out west the AKIs are lower because of the altitude, like 85 instead of 87. Whatever, I'm going to continue to use 89/middle button. E10 most likely, E0 if convenient, but at least now I don't need to worry if all I can find is E15.

    I never worried about using 87/regular either. Some of the more remote places only sell one grade. When the choice is ride or push, I use 87.

    E 15 is not OK for BMW's or any other motorcycles until the EPA gives approval.

    E15 is not OK with me even if the EPA gets bribed to say it is. I suppose I would put a little in a tank to get to the next station with real gasoline but I wouldn't like it. Ethanol in fuel is stupid for both scientific and mechanical reasons.

    The introduction of E15 is a very good reason to plan to fill early when travelling. Then if all you can get is the contaminated stuff you can ride on, or dilute it with the good fuel already in your tank.

    p.s. My 2014 Ford Focus already says it is OK for E0 to E15. My K75 manual says to avoid gasoline adulterated with alcohol.

    You interest me strangely. What is your basis for stating that what's in the owner's manual is not accurate?

    I'm not experienced in the matter for ground-based vehicles, but I presume DOT (and very probably the EPA) have requirements about what goes into the manuals.

    I'm inclined to believe the OEM that:

    1. They've testing or analysis that says E15 is acceptable for the 1250 bikes and that they lack such for the previous bikes.

    2. They will back up that position with warranty coverage for 1250 bikes using E15.

    Personally I'm not a fan of alcohol in street cars and bikes for the several reasons the previous posters enumerate. At the same time I've used E10 in bikes that were approved for it with no adverse effects.

    Ride long and prosper!

    Plenty of ethanol threads around the forum. I spend $11.00/gal for non-ethanol racing fuel for my small engines. The ability of the ethanol to absorb water and create the “white pasty” corrosion is my main problem.

    For your consideration-

    A friend of mine mentioned that he had noticed “black” mold and believed it was actually coming from the “fermentation” from the ethanol. Having enough time to digest his theory, I believe he is correct. Check around the fill-flap, especially on white cars and see what you think.
    I ran across a good example recently-

    I'm confused, we're suppose to use E10 or E15, because its "Better". But it's less efficient than "Pure" gas, providing fewer miles per gallon? So it takes more to do less? And if it's so great, why are aircraft banned from using it?

    Yes, there are high performance engines, used in racing, etc. that use alcohol based fuels and put out a lot of HP. These engines are usually rebuilt after every race, get really bad mpg and have been know to "hand grenade".

    You're referring to methanol. Totally different animal than ethanol. But that's a total thread derail.

    EPA (and the farm lobby) only decide what is in the gas offered for sale, not where it can be used. Approval to use the available gas comes from the engine manufacturers - and BMW has said that the R1250's can use E15 once it becomes available, as it surely will.

    Those who have the option to use E10 or E0 are free to do so, but there are places where there's not another gas station for 50 miles or more. And you don't know what gas it has, if it'll close before you get there, or even if it's still in business. So you fill up when you can with what you can get.

    The BMW manual is describing the fuel that will work in the engine. EPA rules on what fuel is lawful to use in the engine.
