Seafoam has alcohol in it, kinda defeats the purpose.
Ummmm..... No it don't... download and read the MSDS.
Besides, there's hundreds of different "alcohols"... but they ain't the same thing.
For example, methanol ain't the same as ethanol. Methanol pulls moisture from the fuel and suspends it... ethanol pulls moisture from the atmosphere and dumps it into the fuel. In short... methanol = good / ethanol = bad.
I only use SeaFoam when fuel has started to turn, or to clean-up a fuel system... it ain't a "stabilizer no matter what the label says, or what you've been told. It's a solvent, slightly increases octane, and adds volatility (which is what gasoline looses as it degrades). SeaFoam does not "stabilize"... it simply dissolves gums and aids in the ignition of degraded fuel (or more correctly... aids in the vaporization).
I use Sta-Bil in high(er) octane, non-ethanol blended gasoline for storage up to maybe a year in larger tanks like my generator... ethanol-blended fuel is already loaded with stabilizers and the addition of more helps nothing... and ethanol-blended fuel can't be trusted past 2-3 months at best, no matter what is added, or what you've be told. I don't leave fuel in smallish tanks... they get drained, or dumped on the ground, when not in use. And I don't use ethanol-blended fuel in anything... period... ever.
Anything mixed with two-cycle oil gets nothing else added... any quality two-cycle oil already contains high-quality fuel stabilizer.
Gasoline goes bad because of oxidation, and the resulting lose of volatility.
A "fuel stabilizer" is an anti-oxidation chemical... nothing more (some may have a volatility enhancer added).
Ethanol is an oxygenate... it's flat silly to think you can add an oxygenate to fuel and not have it degrade. And it's flat sillier to think you can then add an anti-oxidation chemical to stop the effects. That's like throwing water on your fire, and then expecting it will fire back up by blowing on it.
You can believe your favorite chemical has saved your bacon if'n ya' want... but the simple truth is... it ain't so much you've been lucky, it's more you just ain't been
unlucky yet. Most of it is just snake oil... and damn good marketing. I always get a kick out'a statements like, "xyz works for me." LOL How do you know it works?? I mean really... how do you know?? Just because the fuel didn't go bad with your favorite chemical added don't mean it would have gone bad with out it... LOL.
Anyway... that's my take on all the snake oils.
This is sort'a like an oil thread... huh??
