Sorry I got some peoples panties in a tangle.

But I was wondering if anyone has? Any difference in fuel economy and power? (I presume there would be less)... Would it be worse for the engine?

I was assuming the OP was talking about standard 91 octane E10. I don't know where you guys are getting 'E10 has 95 octane.' Shell makes a guarantee that their E10 has a minimum of 94 octane, and United guarantees 95, however the rest guarantee 91+.

Sure, E10 has a higher octane value than normal 91 unleaded, however maybe it's just me but I rather my car get the 95+ like the manufacturer recommends, over a non guaranteed 93-94 (94 for Shell anyway).

If they made 95 + E10, I would be more than happy to run it but to my knowledge this is not widely available (at least on all the roads I drive on), hence the assumption the OP is talking about 91 E10.

I would not be happy running 91 E10. Your cars though guys so do with it what you will. Just don't critisize me for a simple misunderstanding. You guys are the ones providing false guarantees that 91 E10 = 95+ octane. If the suppliers/manufacturers don't claim over 95 octane, I don't know how you guys can :S
