Don't hate me because i'm beautiful
My Dad had a sand & gravel business while I was growing up and I poured literally hundreds of cans of oil with the push in spouts during services and top ups of the equipment.
In the '60s to mid '70s the cans were solid steel and later they introduced the cardboard ones with the metal tops and they were a PITA if they got wet or dropped to put the spout into.
