STABIL (2) ea 1 Gallon Gold Eagle Marine STA-BIL 22250 Fuel STABILIZER w Ethanol Treatment

What It Is

This is a two-gallon pack of Gold Eagle Marine STA-BIL fuel stabilizer and ethanol treatment, designed to prevent fuel degradation and corrosion in small engines used in lawn mowers, tractors, and other outdoor power equipment, especially during storage or off-season periods.

Fitment & Compatibility

• Machine type: Works with any gasoline-powered lawn mower, riding mower, zero-turn, string trimmer, or leaf blower (2-stroke and 4-stroke).
• Fuel type: Specifically formulated for ethanol-blended fuels (E10, E15) and non-ethanol gas. Not for diesel.
• Measurement check: Use 1 oz per 2.5 gallons of fuel. This two-gallon pack treats up to 640 gallons of gas total (320 gallons per gallon). No deck size or brand restrictions.
• OEM vs aftermarket: Universal additive – no OEM compatibility issues. Safe for all engine brands (Briggs & Stratton, Kohler, Kawasaki, Honda, etc.).
• Storage life: Treats fuel for up to 24 months. Best added to fresh gas before storage.

Key Things to Know

• Quality: Marine-grade formula provides extra corrosion protection for fuel system components (carburetor, fuel lines) compared to standard STA-BIL.
• Installation difficulty: Extremely easy – just pour into the gas tank or fuel can before filling. No tools or disassembly required.
• Common gotcha: Do not over-treat – follow the 1 oz per 2.5 gallons ratio. Overdosing won’t harm the engine, but wastes product and can leave residue.
• Storage tip: Run the engine for 5 minutes after adding to circulate treated fuel through the carburetor. This prevents gum and varnish buildup.

Should You Buy It

Buy this if you own multiple gas-powered lawn tools and want to prevent fuel-related starting issues after winter storage or long idle periods. It’s especially useful for ethanol-prone engines in humid climates. The two-gallon pack is overkill for a single mower – better for a shop, fleet, or shared equipment among neighbors. If you only have one machine, buy the smaller 8 oz or 16 oz bottle instead.
