This is a tip that I got from the pooroldchap YouTube channel [link]. He posts what he terms Workshop Waffles where he talks about things in his workshop.
If you use WD-40 or a similar aerosol propelled lubrication oil this may help you save a few cents. I took an old metal oil can that once contained sewing machine oil. I’m not sure if anything like this can still be purchased or if they’ve all gone over to plastic. A plastic bottle may be usable, but you’ll need a tiny funnel or somesuch to fill it.
The rim of my oil can is raised, so I poked a hole in it with an awl, but not on the very edge. With the can of WD-40 flat on my bench I aimed the plastic tube downwards into a container and sprayed every last bit I could until there was no more propellant. Then I poked a hole in it on the side and poured out any remaining oil into the container that I had sprayed into.
I carefully poured the oil into the top of my re-used oil can letting the oil drain into the hole. Tnen I took a very short sheet metal screw and sealed the hole with it. I got about a half can’s worth of oil to use.
