As you can see the vertices are non planar as they are unevenly distributed in the z axis. Is there anyway to make it into a circle like the edgeloop at the bottom of the mesh?

Yes, for straightening that circle you can do like @Duarte Farrajota Ramos said (selecting that circle and pressing S+Z+0)

But that topology will sooner or later cause issues, so I did a quick gif to show you an example of fixing that topology, it stretched a few lines but nothing too noticeable on the mesh.

What I did:

  1. I straightened that circle with S+Z+0)
  2. Since this object can be perfectly mirrored on all sides I deleted the left and back part to modify it faster.
  3. Then I started to merge some vertices using W>Merge>At Last
  4. I duplicated that part and inverted with S(lock on an Axis)>-1
  5. And then I joined all parts using the Snapping Tool to Merge at the Closest Vertex.
  6. Finaly I Removed Doubles with W>Remove Doubles enter image description here
