How Fuel Stabilzer Works?

I'm not sure if I read this somewhere and it may be completely wrong but does Stabil{for instance}, work by creating a lighter density barrier layer on top of the gas column thereby acting as a barrier between moisture laden air and ethanolized gas? And if that's how it works, is that all it is meant to do?

Not sure about the breaking down of the scientific aspect, but I have been using Stabil, as well as SeaFoam in all my small engine gas, 2 and 4 cycle, for ever since I can remember ... never once did I ever have an issue with gas in any of my machines, from season to season ... and I leave the gas in, never drain it. I do periodically start them just to keep things moving.


I'm sure Googling the scientific breakdown would reveal something.

I use ethanol free gas and never use stabilizer, zero problems. Ethanol is the problem.

Ethanol is only a problem if you've got non-compatible rubber parts in the fuel system and/or get too much water in the fuel (it'll harmlessly handle small amounts better than pure gas). With proper stabilization I've had both ethanol and non-ethanol gas in equipment for 6+ months with no issues.

Ethanol is also very corrosive to aluminum and other metals.

I've never personally seen it be a problem. Ethanol is mildly corrosive to some metals, but not majorly. Methanol is the alcohol that would destroy most fuel system metals.

So do you use E10 to save money over non ethanol gas? If so are you adding the cost of the stabilizer you use? The problem with ethanol is it attracts water and also that it separates from the gasoline over time. I'd rather run ethanol free in everything, no stabilizers needed.

I use them mostly interchangeably depending on availability. But I stabilize any fuel that I'm not 100% sure will be burned off within a month or 2, so any E0 bought for small equipment around the house gets stabilized. Considering I only go through 10 - 15 gallons / year for the mower and snowblower, it's cheap insurance to make sure I've always got good fuel.

The ethanol moisture thing is both good and bad. The good is that it acts just like the dry-gas stuff that used to be somewhat common and absorbs any little bits of condensation in the tank so they get passed through instead of puddling up and causing issues. The bad is that if you get too much water in the fuel, it separates and becomes junk.

Ethanol is hygroscopic, meaning it absorbs water vapor directly from the atmosphere. so if left in the carb it could cause all sorts of issues if left long enough. i know i deal with more than my share of ethanol poisoning of machines every year. clogs main jets. don't even get me started on how the ethanol messes with small engines like weed wacker, chainsaws or leafblowers. they really don't like ethanol and i usually won't even try to repair them for other people unless the equipment is worth enough to justify trying.

You guys are correct about ethanol absorbing water. It also only has about 60% the efficiency of gasoline, producing less heat, therefore not pushing the piston down in the cylinder as hard, and a slower burn, thats why its used as an octane boost. It causes less power and lower fuel mileage. It has to be run a lot richer to be more effective. It is more of an "Inert" ingredient that adds a little bit of oxygen to the fuel mixture and causes a "Lean" condition.
Your actual "Stabilizer" surrounds the fuel molecules to slow the atomic/molecular breakdown of the molecules of the fuel.
Once the molecules breakdown by certain atoms jumping out of the molecule, they become scattered and the fuel wont burn properly and the breakdown leftover byproducts become sludge basically.
