For those who like these type cans, but have never seen them in "action". They will easily fill a 1qt oil measuring fill cup. And as long as one has over a couple of gallons in the can the spout is tall enough to fill a 2qt cup also.......
Here is a short photo demonstration how the can actually works. The can I am using is one that I use still here at home and it is on the floor of my garage.... I use the piece of wood to elevate it from the wet garage floor in winter......

As all can see there is more than enough "room" to fill the containers while the rocker is resting on the garage floor.......
