The refrigerant is just a portion of the problem.
Many of the older systems have other age related problems that caused
refrigeration loss.
They'll also loose anything else you put into there.

I've taken A/C systems off of five Vanagons - Westy and every one of them
had at least one pinched O ring that could have happened at OEM port of
entry install or with later repairs.
