Winter storage re: fuel stabilizer (?)

[RagmopInKona]

Mustang fuel systems are sealed from the atmosphere, so absorbing moisture or evaporation is slim to none.

If it was sealed, it concave the tank , from temp swings, or balloon it depending on what way the temp goes.
Also trusting that "we don't need no stink'n gas cap, " to seal 100% or the evap filter.
A tiny allowed leakage is not a big deal when driven daily, or every few days, but when sitting for months , no beano.
Does he need the sta-bil. maybe not. But ethanol is alky, and loves to suck up moisture. I guess it depends on if you are a betting man or not.
Driving a turbo car come spring that is now lower octane because the ethanol has left the building is no beano. And why I will not store my junk with ethanol blended fuel .
If nothing else, I'd store it with non-ethanol fuel in it.

I won't store anything with ethanol fuel in it. Sta-bil won't hurt anything and it is cheap insurance.

It depends on what type of and storage conditions. Pure, 100% gas starts degrading at about 6 months. E10, 10% ethanol gas starts degrading at 3 months with both types fighting oxidation, water and evaporation.

Storing a car in an unheated space will accelerate water absorption due to condensation. The more evaporation of the gas, the worse oxidation gets causing the formation of solids in the gas.

Bottom line is, does adding Sta-bil to your tank have any down sides? No, it doesn't, it's perfectly safe for your engine as a gasoline preservative. Does not treating your gas have any downside? Maybe, depending on storage conditions, length of storage and type of gas.

Do a quick internet search about the type of gas available in your area and determine what is best for your situation. For me, I have to deal with E10 storing it for about 4 to 5 months so I treat it for peace of mind and if something happens where I don't or can't drive it first thing in the spring, I know I will be covered.

Use it!
Been using stabilizer since car was new in 16,get a good battery tender my battery is 6yrs old and still going strong.
I live in a cold climate and don't have the pleasure of a heated garage.
