I work in large scale manufacturing, the assembly side, and we go through a lot of a cheap version of WD-40 (like a 6oz can a day just at the station I work at). We use it as a temporary lubricant to ease the insertion of 100+ pound “pins” in the joints of the machines. It works well enough but if you spray and come back in 30 minutes it’ll be almost dry to the touch, it’s not a very good long term lubricant (we use a moly grease for that).
