My experience: I use Col Conk Lime, mentholated, as a preshave.
I apply it directly to my face from a standard shave tube that holds a 2.25 oz puck perfectly. I then make a lather, usually with a boar brush. I wash off the first lather, then re-lather and wash off two more times, without needing to apply more soap.
Checking my shave journal, I have done that 60 times with my first tube of Conk Lime. I still have perhaps 20% left in that tube.
