I found, at a health food store near my house, a bottle that you fill up
with your own oil, then pump the top (like the air pump hairspray they
put out a few years ago). The air pressure acts as the propellant. The
only thing in it is the oil you put in and it is reusable. This might
work for you. I try to limit using this type of thing anyway, though,
because it IS still oil.
