Answer
Tim,

Unfortunately, an unlined pond is virtually impossible to clear.  With fish and turtles in it constantly stirring up the mud, and outside water constantly running into it, it won't ever completely clear.

Add a large quantity of floating plants like water hyacinths, water lettuce, or parrot's feather and it will help.

With outside water running into the pond, the oil film could be coming from anywhere.

Hope this helps,

John
