Query: Popper has started to leak motor oil

This popcorn popper worked fine for a few months. It is not straightforward to clean, but that was OK. Today I noticed that oil/grease from the motor unit that stirs the popcorm has started to leak from the edge of the top of the popper, at the edge of the teflon, where this oil/grease can get into food. This is clearly motor grease/oil, looking and feeling much like motor oil from an automobile, not like organic canola oil I use in popping. Naturally, I won't be using this popper any more, as I do not prefer to eat food contaminated with motor oil.
