Oil Drain bolt loosened on its own?

Off-topic a bit--my prior owner said his last oil change was at something like a Jiffy Lube. There was an orange rough-surface Fram filter and a wad of blue sealing wax spanning filter and motor. Is this common?
Also, oil draining struck me as having a slightly purple tint.

Fram oil filters are the worst to use generally. There synthetic ones are better, but Id stay away from them especially the ultra guard filters. Oil could've been royal purple or had a little UV dye in it for oil leaks. As for sealant, never seen anyone use it around a filter.

Wax is for telling Jiffy Lube if anyone has loosened the plug or filter, some people do that to ruin their worn out engine and get them to foot the bill for a new one.
