I’ve had this Royal 880 for about 13 years. What light bulb is anyone using in this? I currently have a 15w in that does not work. Secondly, what oil is anyone putting in the oil port? Lastly, is there anything I can apply to the bag to help preserve it? I’ve decided to dust off my Royal this morning and can figured it could use a bit of extra care. I do run the hepa F&G bags in it.
