    Was a bit below half a tank on the 2011 Prius two hb. Trying out no ethanol gas that I found nearby. Paid a bit more at $3.99 a gallon for 90 octane. What can I expect for those who have tried it with no ethanol?

    I found a no ethanol gas station nearby and since my first tank I will not use anything but no ethanol gas for now on. If its not top tear gas (shell, Exxon, BP, ...) then I would suggest a fuel system cleaner every 3000 miles (I've been using techron which typically costs $8 a bottle but I bought a bunch for 2 for $8 on special at autozone recently). My best tank on No ethanol gas was 60.1 mpg and my best tank on regular e10 was 51.8 mpg. My worst tank on e10 was 44 mpg and my worst tank on no ethanol gas was 52.5 mpg. I am averaging a little better than 10% . I would highly recommend using it only. It costs more but ethanol attracts water which can corrode your fuel system and cause costly repairs down the road.

    i do not know, most here are running e10 without issue. if you pay 10% more, it's a wash.

    Interesting I would love to see 60 mpg. I do a 90 mile commute daily. I do notice car running smoother already or is it me?

    Also was it easier for you put it in the 40 mph with no engine on trick?

    No that didnt seem to change much. The only changes I really noticd was that it was a little bit more powerful and smoother and that I can easily go over 500 miles before mile gas light starts to blink.

    Should be interesting this week even with only a bit more of half a tank of ethanol free.

    For those who are interested in a great additive for ethanol consider Star-Tron. Its especially effective if you live in a high humidity area and may not use gas at a normal rate. The boating community swears by it.

    If it's really typical that gas cut 10% with ethanol has a 10% reduction in mpg, and gas without ethanol costs at least 10% more, the government really needs to rethink this.

    (Addendum: fixed an incomplete thought above, added red text.)

    Ethanol is actually a little cheaper. But you are really saving 20 to 30 cents. And in the long run it costs less.

    Wal-Mart has Techron on sale for $5.00 until sometime in November.

    Same at AutoZone. And it is also on sale for 2 for $8 as well. But those sales end Oct 25.

    Thanks for the info. I'll stop by AutoZone. I have been using Techron for many years. I just put a container in my new Avalon Hybrid that I have had for 5 months.

    14 years of E10 use here, where the entire state has had it mandated... and no evidence whatsoever of those supposed problems. Don't believe the greenwashing.

    Think about it. With the entire state (Minnesota) using nothing but E10, there would be mass revolts if any type of problem actual came from that. Instead, not a peep on the media, from friends, coworkers, or family.

    You obviously havent rebuilt engines or seen the inside of a gas tank. Ethanol attracts water wich in turn causes corrosion to everything in the fuel system. Ive rebuilt several 22rs and sbc 350 and have seen the affects first hand. It is also hell on carburetors. Ethanol has a lesser affect on newer cars built in the late 90s and on. Ford has been making flex fuel vehicles since the 90s (which is not common knowledge). And i dont belive the green washing, last I checked it was the green movemnet and the EPA backed ethanol fuels.

    There's a big difference between ordinary aging and costly repairs. Using E10 is clearly not an issue.

    My cars could not care less if it is E10 or E0. That's the beauty of electric fuel injection. My gripe with E10 is more with smaller carberated lawn engines, as E10 does not stay fresh as long even with Stabil added. Even with fresh E10 lawn equipment are hard starting and stall more often. I fixed the problem by switching to a set of rechargable electric lawn equipment made by EGO. Zero emission too.
    Finding E0 is a losing battle I do not intend to fight.:(

    Fuel tanks dont typically rust out from the inside, fuel pumps rust and gunk up and parts in carburater rust at, a faster rate. Ethanol also has a lower lubricity than gasoline and breaks down the microfilm of oil ond cylinder walls which increases the friction causing more cylinder wear. It also does the same to any other moving parts it contacts in your fuel system like the fuel pump. Ethanol causes accelerated wear which causes people to need to spend more money on their cars to keep thwm on the road. This also takes alot of classic cars off the road too. There are ways to counteract the effects of ethanol fuels like using an upper cylinder lubricant like lucas or gumout, adding stabil to the fuel when the vechicle sits for a while, adding water removers to it, and putting a cylinder fogger in the cylinders before storing the vehicle. All of these still add to the cost along with less fuel economy. Using ethanol fuels is all around more expensive.
