I think they stick because of galvanic corrosion... in this case, aluminum diff cover, steel plug, and copper washer. Copper and aluminum shouldn't be in contact with each other. Plastic would be much more resistant, but an aluminum washer would be better than copper, I think.

I don't think the oil level has anything to do with it, but maybe?
