Stabil vs Seafoam

[buck91]

I know topic has been covered before but I was hoping to find some level of scientific, or at least something greater than anecdotal, evidence on which product is better for long term gasoline (E-10, realistically) preservation.

I have used both before with fine results but I have some "stuff" from my motorcycle to some outboard and even OPE engines which seem very rare use. Certain things like the chainsaw and the motorcycle I like to keep with a full tank for various reasons (ie: chainsaw "grab and go" and motorcycle to prevent tank rust). Currently using marine stabil, but have used the red stabil as well as seafoam in the past for up to a full year with no issues.

Does anybody have real information and which offers the best fuel preservation? I guess its two fold; which one keeps fuel fresh and effective longer? Which one prevents gumming and varnish even after the gasoline is past its effective lifespan?

The blue marine sta-bil. Don't use the red stabil cause it's not ethanol compatible and doesn't work. Trust me.

Seafoam works great 1oz. A gallon

That's if you're dead set on using stabilizer. Honestly I don't bother using anything at all. Just run the engine once a month to circulate the fuel. Most hi quality 2 stroke oils have stabilizer in them already.

New bottle of red stabil I just bought says ethanol compat right on front. They've updated.

I use the red sta-bil, double dose. Works just fine. Last Nov. I put 28 gal. of E-10 in storage for my OPE.

That's complete and utter nonsense.

If you can get E0 fuel thats the first step forward. Blue marine StaBil has more cleaners that the red StaBil so thats why I use it.

I gave up on all that and use AV gas for OPE now, I love it!
