If you really have to pour something in perhaps better something like olive oil if you want to lubricate.
If you want to clean out gunge trapped in the dial you might use liquid soap diluted with water and then rinse with clean water. However even this is to be avoided unless absolutely necessary as the lubricant might even be soluble in detergent.
Olive oil? Wow, never head that one before, nor would I ever try it. I have used rubbing alcohol for years and it works fine and does not damage a single thing. it is an ORGANIC solvent.
