When I changed mine over, I removed the main oil resevior and dumped out as much as I could, the I sucked out as much as I could from the tank under the cowling with a turkey baster. I then refilled them with the oil of my choice and off I went. If you do not want to go through all of this, you most certainly can mix the two unless you have some exotic oil that I havnt heard of. In that case it probably would say "NOT TO MIX" somewhere on the bottle.
