Remember the old style quart oil cans? Stab with a screws driver or use a triangle punt beer can opener and spill 1/2 over your valve cover before zeroing in on the breath hole.

Then there were the stab in spouts that were a miracle and only leaked a little. Also made the 1/2 empty can top heavy so i'd get knocked over and re-lube your bench. I still have a plastic funnel that snaps over the can top like some of these paint can doohickeys but then the big-lube cabal decided to go with the plastic bottles.

I know someone (Rockler?) makes a pain can "lid" that has a pouring spout and a mixing auger combined. Looks trick, but buy that and the can dimension "standard" would inevitably be revised in spite.
