What happens if you don't treat gas before you put it in storage?
If you didn’t treat the gas before you put it in storage, then if it is older than a few months, it most likely is undergoing phase separation if the process hasn’t been fully concluded. You’ll have two layers in the tank – a layer of water plus alcohol on the bottom, and a layer of gasoline on top.
What does it mean when gasoline is not phase separated?
For gasoline that has not phase-separated, but which may appear darkened, this means that it has reacted internally to the point where some of its heavier-end components have polymerized and are forming gums and varnishes. If you were to burn this in an engine, it may well run, but these heavier components won’t fully combust. They will leave deposits in combustion areas of the engine, like injectors and carburetors.
Why do we use fuel additives?
All fuel has a limited storage life. Over time, its quality will degrade and break down because of chemical reactions that happen in the fuel. These reactions can happen faster if the fuel is exposed, over time, to things like air, water and catalytic metals.

Can you restore gas that has been phase separated?
If the gas has phase-separated, then it’s highly unlikely you’ll be able to do anything worthwhile with it. There are some bogus fuel additives out there which claim to “restore” phase-separated gasoline. But what they really mean is that they “might” help gas that has barely started the process. This isn't what most people think of when they decide to try something like that. They're hoping it will magically repair fully-separated gasoline.
