Stabil or Seafoam for long term gas can storage?

[profdant139]

First, I can't believe that this is the first time this question has been posed, but my search of the archives came up empty?!

Anyway, which of these two products (Sta-bil or Seafoam) is better for storing gas for a long time in a can? And how long is too long?

Thanks in advance!

Been using Seafoam for years. Great stabilizer but also cleaner.

Star Tron for anything gasoline.
Archoil for diesel.

So Seafoam for gasoline and Diesel engines is the product best for keeping my grass trimmer carburetor clean. Thank you!

You can also take a gas can down to you local general aviation airport and get some 100LL avgas. This stuff has a 2 year shelf life.

I see you're in SoCal so there aren't many left.

Try Autozone.

That is where I get mine.

Sea Foam appears to be a corporation with many products. Which one should I use to prevent carburetor problems with the snowthrower and riding lawnmower? I always use gas free of ethanol grass Trimmers. I had a Stihl and it needed a new carburetor every spring until I gave it away. Now I’m hoping a Home Depot brand will be better.
Amazon.ca search finds 100,000 Sea Foam products. Locally, in automobile repair shops I see maybe a dozen. Which one to buy?

If using ethanol free gas, I would just run the engine out of fuel and put it away for winter. But if you want to use seafoam, I just eyeball about a shot glass of seafoam per gallon of gas.

Available at any big box auto parts store. I buy it in gallon cans and refill a couple of the 16 oz cans.

suprz, is it ok to use Seafoam in the oil?? It seems like that would mess with the viscosity, which would reduce the ability of the oil to lubricate moving parts.

But I am, once again, revealing my ignorance -- I really know nothing about the chemistry of engine oils.

In small amounts it would be. It would be run with the oil to loosen up any sludge, and built up carbon. I would only run it in an engine that I knew was on the way out to see if it helped. Like that YouTube person, his hydraulic lifters were probably sludged up and they weren't getting enough oil up to the top of the engine and causing the lifter tick. Seafoam being basically thinner with some cleaning characteristics would liquify the sludge allowing the oil to get to the lifters etc.. I would not run it in the oil for an extended time, and change the oil soon after using it

There's a YouTube channel named Project Farm. This guy does semi-scientific comparisons of a bunch of stuff and did one recently comparing fuel stabilizers (excluding Stabil), but he has a lot of videos on the topic. He's not a fan of Seafoam.

I watched the video where he had a high mileage Ford ranger with the typical lifter tick etc.. he used seafoam in the oil, gas and the throttle body, and the tick was gone. Truck ran and idled better. He even did a one year update and the truck was still running and driving better. You sure he's not a fan?
