I got this old school oiler from a grandpa type figure in my life. He was an electrical engineer for Square D back in the day (1940s). I've loved using it, but finally ran out of whatever oil is in it.What type of general purpose oil do I use in this?Dutton Lainson Goldenrod Pump Oiler with flex neck (The flex neck is super helpful!)All of my Google searches come up with car oil change stuff, so I'm hoping this sub can help. I use it whenever I have some metal on metal joint that looks like it needs oil. Or for something like my floor jack that I only use once in a blue moon, but I'm too lazy to research exactly what it's supposed to get.I'm tempted to just throw some 5W-30 in it, but would rather learn and know what it was made to carry.Thanks all! via /r/DIY http://bit.ly/2OWAj2n
