By Patrick Smith · Updated July 10, 2026 · How we review

Ethanol pump gas starts degrading within weeks of leaving the station, and the repair it causes — gummed carburetors on mowers, generators and outboards — routinely costs more than a decade's worth of stabilizer. STA-BIL Storage is the category's default answer for a reason: one ounce treats 2.5 gallons, the bottle's built-in measuring chamber meters the dose, and treated fuel stays start-ready for up to two years. An often-missed detail: opened bottles don't last forever either — Gold Eagle recommends using STA-BIL within two years of opening, so date the label when you crack the seal. Add it to fresh gas at fill-up and run the engine briefly to pull treated fuel through the whole system.

Our verdict

The proven, cheap default for winterizing anything with a gas tank. Just remember it preserves fresh fuel — it won't resurrect gas that already turned.

Most praised

Long-time users report seasonal equipment firing up after months of storage and credit it with ending spring carb cleanouts; the self-measuring bottle gets frequent mentions.

Frequently asked questions

How much STA-BIL do I add?

One ounce per 2.5 gallons of fresh gasoline — the bottle's measuring chamber makes dosing easy. Double-dosing won't hurt, but under-dosing shortens the protection window.

Does it work with ethanol (E10) gas?

Yes. It's formulated for today's ethanol blends and helps prevent the gum and varnish that ethanol fuel leaves behind as it ages.

How long is an opened bottle good for?

Gold Eagle recommends using STA-BIL within two years of opening the bottle — write the date on the label when you first open it.
