SOLVENTS.
From Wiki:
A
solvent (from the
Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute (a chemically distinct liquid, solid or gas), resulting in a
solution. A solvent is usually a liquid but can also be a solid, a gas, or a
supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with
temperature.

Acetone is a good solvent for many plastics and some synthetic fibers. It is used for thinning
polyester resin, cleaning tools used with it, and dissolving two-part
epoxies and
superglue before they harden. It is used as one of the volatile components of some
paints and
varnishes. As a heavy-duty degreaser, it is useful in the preparation of metal prior to painting. It is also useful for high reliability
soldering applications to remove
rosin flux after soldering is complete; this helps to prevent the
rusty bolt effect.
Acetone is used as a solvent by the
pharmaceutical industry and as a
denaturantin
denatured alcohol.
[34] Acetone is also present as an
excipient in some
pharmaceutical drugs.

Although itself
flammable, acetone is used extensively as a solvent for the safe transportation and storage of
acetylene, which cannot be safely
pressurized as a pure compound. Vessels containing a porous material are first filled with acetone followed by acetylene, which dissolves into the acetone. One liter of acetone can dissolve around 250 liters of acetylene at a pressure of 10 bar.

Gas stabilizers work by
disolving the "varnish" as it forms. Varnish is a solid.
X amount of solvent can only disolve the varnish from Y gallons of fuel
After X amount of solvent is used up, you add more to continue disolving the varnish as it keeps forming.
A can of Acetone does the exact same thing...
Nothing is magic.
BTW, Mystery Oil is oil thinned with Acetone with some mint oil added for its unique aroma. I didn't learn this because I just Googled it. I learned this stuff when I was using a sliderule in College studying Aeronautical Engineering.
