No link at source. Question:
Regarding long term storage of gasoline are there any stabilizer alternatives other than Stabil?
What was used prior to Stabil?
Does non-ethanol Gasoline keep longer than the ethanol type?
Google has a mess of stuff that mostly circled back to Stabil.
Thank-you for helping.
Does anyone here use a generic type alternative fuel stabilizer?
Sea foam works for me
Ethanol attracts water and will separate over time. This has ruined many a lawnmower allowed to sit over the winter. You want ethanol-free if you plan on storing it.
Can’t offer any advice on alternate stabilizers.
I have used Stabil, Star-Tron, and Sea Foam to preserve E10 gasoline over winter. I have had no problems with any of them.
I’ve only used the Stabil Marine (blue). It prevents against ethanol-related damage. I rotate every six months from my 5 USGI Scepter fuel cans.
I have access to non-ethanol and store that. Does it keep longer without fuel stabilizer than does the E-gass?
Snow blower has had gas in it two years and not started. What do I do?

I've used that and the oil friction modifier with success.
Couple of questions
How much fuel are we talking about ?
for how long are you planning on keeping it?
under what conditions do you plan to store it?
If you are talking a significant quantity I would buy a 55 gallon drum, add the Stabil and make sure the bungs are good and tight.
Avoid ethanol if possible and get the 91 octane ethanol free if you can.
Keep the drum as stable in temperature as you can, but short hydrocarbons don’t like to say abround very long before going “sour”. Gasoline is a short shelf life item.
Put Sea Foam in it and start it.
It may take running it a few times to get it corrected.
Ethanol gas wont keep over the summer.
Some of the problems of storing gasoline for longer periods of time.
First, ethanol with up to 10% ethanol. Ethanol is soluble in water and what can happen if there is any water around the fuel, including humidity in air, is the you can get a phase separation - a lower octane fuel floating on an ethanol water layer which is corrosive.
A problem with storing both E10 and non-ethanol gasoline, is that the lighter end of the fuel, butane in particular, will vaporize out of the fuel. The octane of butane is about 92, so losing butane lowers the octane of the remaining fuel and makes the fuel less volatile. Being less volatile means the fuel will cause an engine to have a much harder time starting and burning the fuel.
Avoid any ethanol content at all if possible.
Fuel’s enemies are exposure to moisture and air, to light, and to temperature change. Control those things and gasoline should last for many months. Vented gas cans kept in a non-climate controlled garage invite trouble. Newer vehicles have much less tank venting than older models.
AFAIK, all gasoline stabilizers are more-or-less the same.
Mind if I piggyback on to your post with a related question? Should the tank be as full as possible with gas (as treated with stabilizer) when put away for the winter? Or should the tank be as empty as possible (still with stabilizer)? I am thinking of boats and motorcycles in say central Michigan....both are stored in sheds that are not heated.
I have a 2014 boat that has never tasted ethanol and never will! Also used exclusively in my mower! Use boat in the winter up here in NC about once a month. Always have at least 5 Gallons stored.

How much Seafoam per gallon of gas?
Have you tried starting it? If you did, and it didn't work, you may have to clean out the carb/fuel system.
If you haven't tried starting it, I'd suggest trying to drain all the old fuel out, and put fresh in, then try starting it.
I have an old motorhome that sits more than it goes, the generator runs off the same fuel in the main tank. The generator runs maybe once a year for 10-15 minutes. I've not had a problem starting it even though it's been on E-10 for five years now.
I know I need to run it more often, but I really just forget to go do it. Out of sight, out of mind.
I use an enzyme additive. Can’t remember the name. Stabilizes car fuel for at least three years. Or, use 100LL aviation fuel. It never goes bad in storage.
I have used Pri-G for storage fuel, and have used some that was two years old and still ran great in all my machines. The price seems a little high but it only needs about 1/3 ounce for a five gallon container. I have used one bottle for over five years.
