Our take on the Quicksilver Quickstor Fuel Stabilizer

Quicksilver Quickstor is a 12 oz liquid fuel stabilizer for gasoline engines, including ethanol-blended fuel and catalyzed engines. One ounce treats 5 gallons, and it claims to keep fuel stable for up to two years while lubricating carburetors and injectors and guarding the fuel system against corrosion. It is aimed mainly at seasonal storage — boats, mowers, snowmobiles, ATVs and saws. The best new price is $17.54 at Mercruiserparts BAM Marine as of November 4, 2026, with 3 stores listing it new.

Questions and answers

Is Quickstor worth it for winter storage?
Yes, if you store fuel for months. It stabilizes gas for up to two years and adds corrosion protection, which matters most for boats and seasonal power equipment.
How much do I use?
One ounce treats 5 gallons. A full 12 oz bottle treats about 60 gallons, so measure by tank size rather than pouring the whole bottle in.
Does it work with ethanol fuel?
Yes. Quicksilver lists compatibility with regular and ethanol-blended gasoline, and it is rated for catalyzed engines.
Can I use it in a car?
It is intended for small engines and boats — mowers, ATVs, snowmobiles, chainsaws and marine engines — not as a routine car fuel additive.
When is the price lowest?
The best new price seen is $17.54 at Mercruiserparts BAM Marine as of November 4, 2026. Compare across the 3 stores listing it before buying, since hazardous-material shipping can add cost.
