It looks like it comes in 15 ounce cans, so do you mind sharing what procedure you used? 4.25 ounces into each cylinder, manually rotate it x number of times every 6/12/24 hours, then repeat for as long as desired? Then suck out any remainder on top of the pistons before draining the oil? I see some people take it out for a drive before draining the oil, but I think I would rather not have that stuff flowing throughout the engine/seals/etc.
Edit: For everyone, I suppose, I have also seen comments about how the B12 can drastically reduce compression afterwards since it strips away all of the oil from the cylinder walls and compression rings. Is there a preventative solution for this?
