I had a similar issue recently. I went to the store a while ago and picked up a single quart of cheap synthetic oil, only to be used for gun lube. I wrote GUN OIL all over it. The other day, after having used it for the second time, I was chuckling to myself thinking I wonder if this will last me 100 years, or 150 years? when the bottle slipped out of my hand onto the floor without the lid on.
