I use Sta-Bil, but find the 4 cycle engines run a little rough until you get the first tank ran out.
I like to start the cars once or twice a month even though they are in a heated garage. On nice days, I'll even take them for a short cruise unless there is salt on the road.

I've used Sta-Bil, but haven't found that it helps, or hurts, 'stored' gasoline. And, that applied to cars, mowers, etc. But, for the smaller engines, mowers, etc. I typically run them dry, and follow that up w/wiping out the tanks, to ensure the tanks are empty, before winter storage. For the cars, I'll usually start them up monthly, and run them for at least 20 minutes, and try to take them out for a short spin, if the weather permits. I don't use Sta-Bil anymore.
I swear by Seafoam for ALL internal combustion engines. I have a power equipment repair business and use it in almost all my repair work. I like it better that Stabil because it also cleans fuel systems. It can also be used in the oil. Stabil is also a very good product however I like Seafoam better.
I've said this before and gotten torched but the truth is the truth.
There is no data to prove that any of this works. The refiners say they have no interest in testing aftermarket additives. The people who produce the additives have never produced any research proving their products actually work.
We're left with anecdotal evidence. It's similar you religious faith. You either believe or you don't. You'll notice the various responses in just this thread. We have a number of believers and a number skeptics.

as many of us say on the forum, "your results may vary"...
I have had gas sit in an un-started vehicle for periods much longer than 90 days with no apparent damage. am I lucky, maybe....
I also have gas in 5 gal cans for emergency use that may be over a year(s) old; once again, no ill effects when I use it in a lawnmower, etc.. am I lucky, maybe...
but I don't disagree that ethanol is hydroscopic, and I have no clue if 'additives' will cause water to be reabsorbed in gasoline; BUT it should be simple to test the theory.
I seem to remember someone(s), showed a water separation in a clear container. simply adding 'additives' to the separated mix would show what happens short term, and then mixing up and waiting to see if it separates again would show long term effects...
nope, i'm not going to volunteer to do it; but it would clearly show if there are any benefits to these additives.
When I worked oversea's, I stored my car for a year at a time. I used a product called "Fuel Fresh". I put the prescribed amount in and then filled the tank. The following year when I returned, the car started right up. Never had a problem with this product. I think Sta-bil is basically the same. Don't know about Sea Foam or the rest.
As long as you drive enough to consume at least one tank of fuel per year (including E10) in a car there is no need for any additives. If you store the car during winter months, fill the tank with fresh fuel just prior to winter storage.
For small gas engine equipment, if you are not using it at least once a month, drain the fuel after use and pull the starter cord with the ignition on until you are sure that virtually all of the fuel beyond the tank is consumed.
I also leave the chain saw that I use once or twice a year in the sun for a couple of hours with the fuel cap off to ensure that the slight remaining residual evaporates... never had any fuel system problems.
I don't use anything. All my mowers, trimmers, blowers and other small engine powered both 2 cycle and 4 cycle items that are stored in a shed over the winter start up just fine in the spring. My cars/trucks never sit long enough for gas to go bad in them. I have seen more bad than good come from people using these admixture products.
The first choice is no ethanol gas. It will last MUCH longer without issue.
For chainsaws, many instruction books/owners manuals recommend running the saw out of gas before storing.
Otherwise add some Sta-bil.................

my wife's 2012 Grand Sport was getting "check engine" light warnings for the air/fuel mixture. The service department at the Chevy dealer told her it's because she's not filling her tank with fresh fuel often enough (she only has 6,000 miles on the car) and advised her to either drive the car more or use non-ethanol. No check engine lights since she changed over to non-ethanol.
Anecdotal and not scientific for sure, but this seems to have solved this particular problem for her.
