Mpg 2013 jk

The first month I got almost 20 MPG. Now I am at 17. I have a new 2013 JK 6 speed and I am not a crazy driver. Maybe it's the gas I am using? I just noticed thus

It could be. It should be about the time of the year where they start switching from the summer blend to winter blend. But I am not a mechanic but that would be a guess.

I've noticed the same problem on my 2012 jku. A few weeks ago I was averaging the best mpg I've had so far with the jeep. 21 mpg ave. last weekend I hit an all time low of 14.9 mpg. I don't think I've ever gone below 16.9 before. If it's not the gas it could be something else. I'm keeping an eye on it then I'll check with the dealer to see if it's something more serious.

I noticed the gas I am getting is 10% ethanol, is that bad?
