Our take on the STA-BIL Storage Ethanol/Gasoline Fuel Stabilizer 16 oz

STA-BIL Storage is a gasoline additive that keeps fuel fresh for up to 24 months and fights the gum, varnish and corrosion that build up in stored fuel. It is aimed at small engines and seasonal equipment: mowers, chainsaws, snow blowers, generators and boats. The 16 oz bottle treats up to 256 gallons at 1 oz per 2.5 gallons. At $13.58 at Amazon as of November 4, 2026, it is the lowest new price among the two stores listing it.

Questions and answers

Is STA-BIL Storage worth it for a lawnmower?
Yes, if the mower sits for months with gas in the tank. Treating the fuel before storage is the cheapest way to avoid a carburetor cleaning in spring.
How much do I use per gallon?
One ounce treats up to 2.5 gallons. A 16 oz bottle treats up to 256 gallons, so it lasts several seasons for most homeowners.
Does it work with E10 or E85?
It is formulated for ethanol-blended gasoline and is listed as compatible up to E85. It does not remove ethanol; it slows the corrosion and moisture problems ethanol can cause.
Can I use it in a 2-stroke engine?
Yes. It is compatible with all 2-stroke and 4-stroke gasoline engines, including mixed fuel for chainsaws and trimmers.
