I guess I am different. I have been casting bullets for 35years. I have never even lubed the sprue plate on an aluminum mould. I smoke my moulds when I flux my melt and that is only once before I start casting. I own 20 various Lee moulds.
When I used steel moulds, I lubed them after I finished a casting session with a light oil and only to prevent rust. I sold all of my cast iron moulds and now use aluminum exclusively. Aluminum mould are lighter, they heat/cool fast, and do not rust.
