What's better for storage - Sta-Bil or seafoam?

[repairman54]

I never run my gen set carb dry. E0 and quality fuel stabilizer. Running dry never completely removes all the fuel anyway. That's where the quality stabilizer comes into play. I stabilize my fuel cans, not the individual equipment. Even when I was stuck with E10 a quality stabilizer was used successfully. I have a ton of small engines in my care.
PRI-G is now my go to stabilizer.

Give PRI-G a try , I believe their diesel version was made for long term military fuel storage.

Seafoam has 2-propanol alcohol in it- according to msds similar concentration to E10 gasoline.

I usually treat with Sta-bil and then top oil with ND SAE30

I personally prefer Startron gas additive. Stabil gunked up carbs.

I also believe draining the carbs is the best, however if your carbs have a paper style gasket, they will most likely leak quite badly when they are first filled up after being stored dry. So just be prepared for it.
If the seal is a rubber o-ring style, it should be fine.

Stabilize the fuel in the tank.

PRI-G says 5 yr storage on the bottle.

I have never used stabilizer and never had problems.

I use non ethanol premium, stabil and TCW3. Fill the tank and drain the float bowl of carb.

I won't use seafoam, because I don't like adding more alcohol to the fuel.

I use tcw3 @ 640:1 and sometimes stabil. I run e-10 fuel, but last fueling of the season is non ethanol with the TCW-3.

Been using the blue Stabil for many years. But I also start filling my tank with REC 90 gasoline the last couple of fill ups before winter storage. Ethanol free gas. Luckily the Marathon station not too far from me sells it. Usually a dollar to a dollar and a half more than regular. But nothing to worry about with a 4.5 gallon tank. I still pour some blue Stabil into the REC 90 and run it a bit. Like I said, the last few fill ups late in the season when I know riding days are limited. The following spring it starts like it had just been running. Every year.

it does give me a good laugh that folks are more willing to spend $10 on a gas treatment instead of spending 10 minutes draining the fuel system.

I do both.

Run Seafoam in my gas for snowblower and lawnmower. End of respective seasons, lawn mower turn off fuel valve and let carb run dry. Whatever gas is in tank stays in until next spring and gets used up that summer

Snowblower I suck whatever gas is left in tank out, then start and run carb dry, then take out carb drain bolt for any risidual fuel. No fuel shut off on my snow blower

STA-BIL 360 fuel stabilizer.

 

[Mav123]

Is Pri-G really better than Stabil Marine 360 used a non-driven car?

 

[Ang]

Stabil 360 Marine is probably one of their top tier anti-oxidants.

So you are saying to use Stabil 360 marine in everything, including cars, instead of regular Stabil?

Probably not ideal for a car

Probably not ideal for a car

Why?
And how many other marine product suggestions did you take issue with in this thread?

 

[ka9mnx]

I use TCWIII and Seafoam in my OPE. This September I started my generator for the first time for Hurricane Helene since it was filled after Hurricane Mathew. Started on third pull, as usual, and ran fine. That's what, just under seven years?

Yes.

10 years ago, I had a bottle of the red Stabil form crystals in it. I have read a number of cases on motorcycle forums where they had to clean red crystals out of carbs to get the engines running again. The motorcycle people recommended against using then basic red stabil formula. These red crystals do not dissolve when new gas is introduced into the carb.

Since then, I have used the blue marine stabil 360 without issues. I use it in my boat, lawnmower, generators and motorcycles.
I add 1oz of TCW-3 2 cycle oil into a 5 gal gas can, along with the marine stabil 360, and use this mix to winterize everything.

Found this on another forum. Key point is past shelf life, and next key point it is specific to a certain time period.
