So in the instruction manual and on the fuel hatch door it says that you can use the E10 Ethanol blend fuel.

Now let me just say first that I've only owned my CL9 for 3 months and I've never put anything less than Unleaded-95 in it and I don't intend to use the Ethanol blend. 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?

Cheers
