What do you fill it with? Is 10% ethanol OK?

    Chrisfix installed a E85 system on his Prius like two months ago and I was surprised of not seeing a discussion about that in this forum, as far as i know the guy uses that as his daily.

    There are a couple of stations in my area which sells ethanol free. What is Toyota's position on that?

    As long as the right octane, it's fine. Just not likely worth the extra cost.
