What is the best gas Fuel Stabilizer?

I had been using West marine brand but they have discounted.
 
I use Sta-Bil Marine Stabilizer in every tank.
 
STA_Bil is made by Gold Eagle a Chicago area company. I did biz with them starting about 1984 and for many years after. I am now retired. They were a class act then and I bet they still are. Their website is www.goldeagle.com I use STA-Bil seasonally in my cars, boat and motorcycle (will did 'til I sold). No fuel problems. Is it the STA-Bil? Maybe.
 
IMHO the very best fuel stabilizer on the market is non-ethanol gas.

I started using K100. It cleaned up over a 100 gallons of gas and can stabilize for two years. Hard to find but is available online. Go to their site. I went from not being able to hardly start my engines to running like I had fresh gas.
 
FWIW-As a gasoline stabilizer, original (red ) Sta-bil Fuel Stabilizer is twice as effective per volume unit as the blue Marine Sta-bil according to their company rep at headquarters. Marine Sta-Bil is even advertised as a Fuel Treatment, not "stabilizer", (though it has some in it) as other additives take the place of 1/2 the stabilizer found in the red.

That said , I just buy Valv-tect gas that is already stabilized, and just add some red Sta-bil or gas Valv-tect at last big fill of the season with 1 grade higher octane rated gas for winter layup, for better protection just in case winter layup gets prolonged next season.

But adding more than the mfgr recommends can be counterproductive... as after all, it's not gas your boat was designed to run on.
 
I wouldn't touch K100 with a 100 foot stick it is Alcohol based exactly what Ethanol based fuel doesn't need, the enhanced ability to absorb moisture. I would go as far as saying their website is a fabrication.

Our marina went to ValvTect fuel this year. "Only a few pennies more" than the 89 Unleaded they used to have. We usually run often enough that I wasn't adding stabilizer. We knew we wouldn't be running for three months last winter and I added Red StaBil. With the new fuel I won't be doing that again. Some of our nearby GATE gas stations have 89 Unleaded on a dedicated automotive island. The trailer boaters can save about .75 a gallon by trailering there instead of using the marina at the ramp.
A little OT, but our marina does lots of walk-in fuel business for its unleaded gasoline. It's out of my way by car, but that's what I buy now for my lawn equipment. Those small engines hate ethanol. Maybe I should put it the other way. Ethanol hates small engines...
 
I use Startron at every fill up, and winterize with red Stabil that I buy at Walmart where it seems to be cheapest.
Same place I buy bio-degradable toilet RV paper, treatment chemical for my head, and sometimes the pink anti-freeze to use in my fresh water, waste water, and AC.
Many things I will only use products marked for "Marine Use", but some things I won't waste the money if another packaged product will do the same job.
 
Guess I have been lucky or had the right sources for gas the last 21 years. Valvtec at first marina and have always had non ethanol fuel at marina's here on Kentucky Lake (Tenn / Cumberland Rivers). Tanks are never filled unless we are headed to the Gulf, never added stabilizer except in 08, when too much internet reading convinced me it was necessary. Never had a fuel related issue. I 'think' fuel that is kept cool all winter is less prone to issues than say someone in Fla or south or west coastal warmer enviroments. Just been my experience, and opinion, no facts to back it up, just experience. Same applies to needing to fill fuel tanks to prevent in tank condensation . . . .never had that happen either.
