The upper thread keeps breaking and there is oil on the thread that is stitched in the cloth. The machine keeps jamming and the hand wheel won't turn. Very aggrivating!
You need to remove the bobbin from the "race" by following the instructions in the manual. Give it a good clean and remove any bits of fluff and thread. Remove the upper thread also andmake sure that the tension wheel is clear of any broken threads and is on the correct setting. It may have been threaded wrong. The hand wheel not turning sounds like the bobbin area is jammed also.

Difficult to say without really seeing what's happening and which thread is breaking. If the top thread is breaking, check to make sure the thread is not wrapped around the spool pin or a thread guide.
Just some things to try:
Install a brand new needle.
Be sure to clean and remove all the thread pieces, lint, etc from under the needle plate, around the shuttle, etc. Oil as instructed in the owner's manual.
Remove all the thread from the machine. ALWAYS RAISE the presser foot when threading the top and rethread the machine from the beginning. Check that the thread path is correct and the bobbin is loaded and threaded correctly.
Well, before I did all that (which may be necessary), I would take a piece of UNWAXED dental floss or hand embroidery floss and floss between the tension disks. You mentioned that you were suddenly breaking threads; there may be lint or loose threads or both seated between the disks, preventing the thread from seating properly. Then,
I would take the embroidery unit off and try to do some sewing with it, to see what results I got. If you can catch and bring the bobbin thread to the top with the top thread, I am doubtful that your timing is off. Sew a line of both straight stitch and zigzag stitches, and see if the stitches are balanced. If not, you may have a bobbin tension issue, and if so, most bobbin cases can be adjusted.
I think you'll find, though, that things will improve considerably when you have cleaned out the upper thread path and tension disks. Make sure when you do that, that your foot is raised, so that the disks are spread. Oh, a drop of sewing machine oil wouldn't hurt either--generally you should put a drop of oil for every 5 hours of embroidery.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.
* Change your bobbin There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.
* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.
