Ethanol Shield Fuel Stabilizer 1 Gallon (128 oz) Concentrate — Treats up to 1,280 gal, prevents corrosion & removes water

Ethanol Shield 1-gallon fuel stabilizer is a concentrated gasoline treatment that stops ethanol-related damage, prevents corrosion, removes water, and stabilizes fuel so one bottle treats up to 1,280 gallons.

If you store equipment or vehicles, run small engines, or want to keep fuel systems clean year-round, Ethanol Shield is formulated to protect both 2-cycle and 4-cycle engines. This product combines antioxidants, corrosion inhibitors, a phase-separation blocker, and detergents to reduce fuel aging, help with cold starts, and guard non-ferrous metals above and below the fuel line. Use it at a simple 1 ounce per 10 gallons ratio; note that a pump is not included with the jug.

How does Ethanol Shield stop ethanol-related problems?

The concentrate targets ethanol’s common failure modes: water attraction, phase separation, and corrosive attack on metal and fuel system components. Its multi-action chemistry both neutralizes existing issues and leaves long-lasting protection in the tank and fuel lines.

• Phase separation inhibitor prevents water from separating out of gasoline/ethanol blends
• Vapor Corrosion Inhibitor (VCI) protects non-ferrous metals above and below the fuel line
• Superior antioxidant package slows chemical breakdown of gasoline
• Detergent package cleans deposits to support consistent combustion

Will this stabilizer work with my lawn mower, boat, or motorcycle?

Yes — Ethanol Shield is safe for both 2-cycle and 4-cycle engines and is OEM-tested for a wide range of equipment. It bonds two-cycle oil to ethanol-gasoline mixes and provides upper-cylinder lubrication to reduce wear and improve starting.

• Compatible with small engines, marine, powersports, generators, and autos
• Bonds 2-cycle oil to gasoline/ethanol blends for reliable lubrication
• Combustion Cool Technology (CCT) helps reduce hot spots and deposit buildup
• Proven in OEM testing to be equipment-friendly

How long does treated fuel stay good, and what are the performance benefits?

Treated fuel resists aging for extended periods, significantly lengthening storage life compared with untreated gasoline. You’ll notice easier cold starts, fewer gum and varnish deposits, and reduced need for high-octane compensation as engines age.

• Stabilizes fuel up to three years under recommended conditions
• Removes free water and conditions rubber and plastic components
• Reduces varnish and deposit formation for smoother running
• Helps maintain octane response and combustion consistency

How do I use the 1-gallon bottle and what coverage can I expect?

Dosage is straightforward: add 1 ounce of Ethanol Shield for every 10 gallons of gasoline. One 128-ounce jug treats up to 1,280 gallons, making it a practical choice for fleet maintenance, seasonal storage, and frequent refills.

• Ratio: 1 oz per 10 gallons of fuel (mix before storing or use)
• 128 oz bottle treats up to 1,280 gallons total
• Shake or mix fuel briefly if possible to ensure distribution
• Pump is not included; pour carefully using an approved funnel or pump

Who is this for? Ethanol Shield is designed for owners and maintainers of small engines, marine operators, powersports riders, fleet managers, and anyone storing fuel or equipment. If you want to reduce ethanol-related failures, protect metal components from corrosion, keep stored gasoline reliable for months or years, and avoid costly repairs, this product delivers concentrated protection and long-term value. It’s also suited for professionals who service equipment and need a trusted, OEM-verified stabilizer to recommend.
