Is it definitely oily? Or is it just foamy brown shite?
Foamy brown shite is classic engine rusting from the inside out, dishwasher tablet and a few flushes ought to fix that and then just keep on top of coolant changes.
Black and oily - i.e. globs floating on the surface - probably your oil/water heat exchanger shafted, reasonably easy to replace.
Ignore what 99% of people say about oil/water mixing with XUD head gaskets, I've seen maybe one actually mix their oil and water when the head gasket has gone - they don't fail around the oil/water jackets, they always blow either between cylinders or into a waterway and pressurize the coolant severely - if the head gasket is going, every time you take off the rad cap you'll get a massive HISS for a long time and gurgling and when it's really going, the heaters will go cold when you put your foot down and the coolant temperature gauge will just go past 90*c.
