That's really low compression. I would put some oil in the cylinders on top of the pistons and redo the compression test. If it improves, you have bad rings, if it doesn't, you have bad valves. However, with your oil being thinned out with fuel, I am betting you have bad rings.

Found that the head was cracked and causing fuel to get into engine to cause fuel in oil
