Recommended fuel additive?

[mlts22]

Bought gas at a gas station a few blocks away from where I normally go. Filled my generator up... noticed it surging.

What is a recommended additive, if there exists one, that might be able to undo what that five gallons of marginal fuel possibly did? I know about SeaFoam, but am wondering about other brands and offerings. Generally I have zero issues with surging/hunting, so this was an odd exception.

Seafoam contains a large percentage of rubbing alcohol. With the amount of ethanol forced into our gasoline, water in the gas should not be an issue anymore and certainly no reason to add products like HEET which just add more alcohol.

Products with Polyether Amine are proven to clean without leaving any deposits of their own. Gumout Regane, Techron, and redline SL-1 among some others all contain good amounts of PEA, and no alcohol.

I would use this "HEET" Clicky

If the problem is actually water in the gas, and not a dirty carburetor, Stabil may be a better choice. Stabil actually absorbs water molecules which is why it is good for long term storage. Seafoam is manufactured more as a cleaner though they state it will preserve gas as well. I am not sure Seafoam will have much affect on water in your gas.

x2 on the Seafoam put it in all my equipment including the generator,

If you've had a lot of rain recently, could be you have some water in your fuel. I make it a point to never fill after a rain storm or a tanker delivers gas as this can stir up all sorts of cr-p in the ground tank.

SeaFoam for cleaning gunk from fuel system
Sta-Bil for storage

Sea Foam additive would be my first choice. StaBil second choice.

I have great results with Sea Foam. Have a snapper lawn mower that was surging and two treatments of sea foam in the gas tank cleared it right up. I get my Sea Foam at walmart.
