I think steel containers are best due to less leakage of vapors. Are not all plastic containers much more porous?

Thanks for the explanation. It helps me understand how the stabilizer works.
The suggestions you provided are interesting. Thanks for the links.
Getting information about "how it works" has almost been futile.
I am hoping that Molakule might be lurking around and have some input...
You're welcome Frank!
If you go to Bell performance's youtube page, they have many one hour or longer videos all about fuel. Storage, ethanol issues, fuel treatments and the like. They aren't very exciting videos but they are very factual and they are NOT an advertisement or product plug type videos at all. You will probably learn something if you take the time to watch them.
If you do enough research you will probably come away with a few points to keep in mind when discussing gas and its storage.
1. Gas is similar to most other volatile solvents. It wants to evaporate in open air and it is hygroscopic whether it has ethanol in it or not. To keep the gas fresh and prevent it from evaporating, Store it in a tightly sealed container located in a steady temperature environment. I like the No-Spill gas cans as they use thicker plastic than most and they seal very tightly. Plus the dispensing button is very easy to use.
2. Most of the better fuel treatments and stabilizers are a combination of pretty nasty solvents. Butyl cellosolve, Xylene, ether, benzene, ect. All of them will help clean the fuel system, remove water, stabilize or even slightly boost the octane and make the gas more volatile and explosive. The fuel treatments that contain kerosene, mineral oil, pale oil or any type of product that says it can be used both in the gas and the oil are not going to do much for keeping the gas fresh, the octane high, removing moisture or cleaning the fuel system, avoid them.
3.The better fuel stabilizers will have a treatment rate of 1 ounce to 10 gallons of gas, or less. Anything with a treatment rate higher than that, say 1 oz to 20 gallons, just isn't realistic and isn't going to keep fuel fresh. For long-term storage, I won't use any product that has a treatment rate of higher than 1 oz to 5 gallons. My preferred storage product right now, K-100MG treats at 1 oz per gallon....
4. No matter which fuel stabilizer you choose, you need a tightly sealed container system, stored in a temperature regulated environment. No product can make up for those 2 factors. A leaking fuel system IE: leaky fuel lines, gas caps, vent valves, are going to cause a problem. A gas can or a vehicle being stored outside when the temperature fluctuates from 50F to 90F in a day will also degrade the gas very quickly. Do the best you can to avoid the temperature changes.
5. Keeping the gas tanks or containers full will allow less airspace for the fuel to evaporate into and less space for condensation to form. It helps so try to keep the tanks topped off.
Following all of the above, using a good fuel stabilizer and storing the fuel in good conditions should make e-10 gasoline last at least a year. After 18 months of storage, avoid using the gasoline in an engine that is carburated. Fuel injected engines are less prone to problems with degraded fuel. A good way to use up stored fuel is to dump it into your car and then top off the tank with fresh gas.
E-10 gasoline with no treatment added, stored in a tightly sealed container that is temperature controlled should last about 5 months. E-10 gas with no treatment, stored in a poorly sealed container with large temperature fluctuations will start to go bad in about 2 weeks and will be completely unusable in about 2 months.
This is just what my research and experience have shown me. Do your own research, come back to us and let's compare notes.
