Front Door Finish

Got a question, and I suspect someone on this board has some good info. Bought a house a year ago, and it has a front door that appears to be solid mahogany, in a very dark brown finish. It is not varnished, but has a dull finish that might be oiled? The door isn't weathered, but gets evening sun. I have researched finishes and think it might be finished with tung oil, Australian timber oil, or something similar. Don't know enough about this to know, as my previous houses I always did with stain and multiple layers of spar varnish. I would rather not go that route with this door.



A friend of mine is a wood working guy, and he said Ephines (sp?) finish was highly-rated, but only products I could find from them looked to be a clear sealer.



Anyone have any advice? I don't mind having to apply a couple of times per year to maintain. But don't want to get into the position of having to sand it all down, stain, varnish, etc - like I used to go thru with my other houses with west-facing front doors.



Thanks in advance for any advice.
