Quicksilver Quickstor Fuel Stabilizer 12 oz – Long-Term Storage & Protection

Overview

Quicksilver Quickstor Fuel Treatment and Stabilizer 8M0047922 is engineered for broad compatibility with all 2- and 4-cycle gasoline engines, including cars, trucks, motorcycles, ATVs, snowmobiles, marine engines, lawn equipment, and power tools. Safe for catalyzed engines, it’s a practical companion for seasonal use and off-season storage. Add it to fuel before long-term boat storage to help preserve quality and performance for future runs.

What it does

This stabilizer helps prevent the fuel from breaking down or oxidizing, a common issue with ethanol blends and traditional gas. It also aims to curb fuel-system corrosion and keep gum or varnish from forming and settling in lines, tanks, carburetors, and injectors. The formula is designed to align with Mercury Marine original equipment manufacturer specifications to maximize engine compatibility and reliability.

• Stabilizes fuel for up to two years, giving you peace of mind during extended storage
• One ounce treats five gallons, making it simple to dose for mixed-fleet needs

In everyday terms, you may notice easier starts and steadier idle after a period of fuel storage and return to use, thanks to cleaner fuel delivery and fewer hard residues. While results can vary by engine and climate, the product is positioned as a careful, consistent treatment to support fuel integrity over time.

Ideal uses

• Boats and marine gear kept idle during off-season or winter storage
• Generators, lawn mowers, snow blowers, chain saws, and other powersport equipment stored for months
• Any 2- or 4-cycle carbureted or fuel-injected gasoline engine that may encounter ethanol-gas or extended storage periods

Using Quickstor as part of your storage routine can help manage fuel quality in environments where fuel sits for an extended time. The integration with Mercury Marine OEM standards adds a layer of alignment with established engine components and maintenance expectations in marine and powersports settings.

How to use

Follow the guide: add to fuel before storage and use the specified dosing to treat your fuel supply. A typical guideline is 1 oz per 5 gallons of fuel. After treating, run the engine briefly to circulate the stabilized fuel. This approach is designed to support storage readiness without requiring immediate engine service when you return to operation.
