STA-BIL Storage Fuel Stabilizer 8 oz 12-Pack — Keeps Gasoline Usable up to 24 Months, Prevents Gum & Corrosion

When vehicles, boats, lawn mowers, or small engines sit unused for months, gasoline can degrade, form varnish, and corrode fuel components. STA-BIL Storage is formulated to stop fuel breakdown, remove water, and shield metal parts so engines start easily after storage without the hassle of draining tanks.

How does STA-BIL Storage keep gas usable for months?

The formula bonds with volatile fuel components and limits oxidation that causes gum and varnish. It stabilizes both ethanol-blended and non-ethanol gasoline, maintaining fuel chemistry so combustion remains reliable after long storage periods.

• Treats fuel to prevent oxidation and breakdown
• Compatible with ethanol and non-ethanol blends
• Removes small amounts of water from the tank to reduce corrosion
• Maintains pump- and injector-friendly fuel properties

How do I use the 8 oz STA-BIL bottle for different fuel quantities?

Measure according to the recommended dose: add 1 ounce of STA-BIL Storage per 2.5 gallons of gasoline before filling. After adding product and fuel, run the engine for a few minutes so treated fuel circulates through the entire system.

• Dosage: 1 oz per 2.5 gallons of gasoline
• Pour into tank first, then add gasoline to mix
• Run engine ~5 minutes to treat the full fuel system
• Each 8 oz bottle treats up to 20 gallons of fuel

Will STA-BIL Storage protect my engine and fuel components?

Yes — the stabilizer protects against gum, varnish, rust, and corrosion while helping keep carburetors and fuel injectors clean. This reduces the chance of sticky deposits that make starting difficult or cause poor performance after storage.

• Prevents corrosive damage to fuel system metal parts
• Helps keep carburetors and injectors free of deposits
• Minimizes gum and varnish formation on fuel lines and valves
• Helps prolong engine life by protecting components

What are the shelf life and expiration details for STA-BIL Storage?

The product remains effective for two years once opened and up to five years from the production date printed on the bottle. The code is a 5-digit number (YYDDD) on the back: YY = year, DDD = day of year.

• 2 years of protection after opening
• 5 years from production date (check YYDDD code)
• Store in a cool, dry place to maintain effectiveness
