O the messes I made with those things.
No offense meant, but you must be young, like in your 20s.
Those are oil can spouts. In the olden days, like 50 years ago, when I was pumping gas at a Union 76 and Texaco station, oil came in round cardboard cans with a metal top and a metal bottom. You took one of these spouts and punctured the top of the can and quickly turned it upside down when inserting into the oil fill of the car.
The really fun part, if you were brave, was puncturing the top of one of the one gallon cans like it, that oil came in for an oil change. After one or two attempts to hold that 1 gallon can inverted, most idiots decided it was easier to use a funnel.
Cheers to ya,
and happy oil change time,

..Someone will chime in about glass oil jars with long metal spouts.
There's probably someone here who rode their pet stegosaurus down to the tar pits to scoop up oil in coconut shells.

I used to use a church key and funnel.

Good Lord I'm feeling old. I Still have some of my oil spouts.
Checking and buying oil at the gas pump seems like another thing of the past. In fact I can't remember ever getting oil at a gas station, always bought it at a store and added it myself.I was in high school during the "gas crisis" and working at a corporate Mobil (pre Exxon) station. We sold a lot of oil and just about every can got stabbed.
Ya; I have both the flexible spout and rigid type can spouts purchased in the 60'S. I also have a couple cans of GM power steering oil from the 80'S. That oil is getting ancient. Time flies, but I never tried to Myself.
Calling Fred Flintstone......
