This case of STA-BIL Fuel Stabilizer packs twelve 10 oz bottles of the gasoline additive that keeps stored fuel fresh for up to 24 months. It's built for anyone who parks equipment for a season: boaters winterizing outboards, RV owners storing a generator, classic car keepers, and homeowners shelving lawnmowers, chainsaws, and pressure washers between uses. One ounce treats 2.5 gallons, so a single 10 oz bottle covers 25 gallons. Buying by the case makes sense when you're treating multiple tanks across a fleet of small engines, vehicles, and watercraft. You can browse the full automotive and RV lineup for the rest of your storage routine.
STA-BIL works by preventing the oxidation that turns idle gasoline into gum and varnish, the residue that clogs carburetors and fuel injectors after a few months of sitting. The formula removes water to stop corrosion inside the tank and fuel system, and it protects against rust over the storage period. It contains no alcohol and is oxygen sensor safe, so it won't damage modern emissions hardware. It's compatible with all gasoline-powered engines, both 2-cycle and 4-cycle, and works in every ethanol blend up to E-85. For long-term storage, you add it to fresh fuel, run the engine a few minutes to circulate the treated gas through the lines, then top off the tank. Made in the U.S.A.
Reach for STA-BIL anytime an engine will sit longer than 30 days. Treat the tank before winter on a boat or motorcycle, before summer on a snowblower, or whenever a backup generator goes back on the shelf. Treated fuel starts clean and fires on the first few pulls instead of fouling out or needing the carburetor pulled and cleaned. For engines coming out of storage or needing internal protection, pair it with STA-BIL fogging oil, and for fuel system corrosion control look at STA-BIL rust stopper. Single bottles are available in the same 10 oz size if you don't need a full case.
One ounce of STA-BIL treats 2.5 gallons of gasoline, so a single 10 oz bottle covers up to 25 gallons. A full case of twelve bottles can treat roughly 300 gallons total, which is why it makes sense for fleets or multiple small engines.
Yes. The formula works in all gasoline blends including ethanol up to E-85. It removes water to prevent the corrosion that ethanol fuels are prone to during storage, and it contains no alcohol. It is also oxygen sensor safe and won't harm modern emissions components.
STA-BIL keeps stored gasoline fresh for up to 24 months. Add it to fresh fuel, run the engine a few minutes to circulate the treated gas through the fuel lines, then top off the tank before storage so there is no airspace for condensation.
It works with all gasoline-powered engines, both 2-cycle and 4-cycle. That covers cars, motorcycles, boats, generators, lawnmowers, chainsaws, pressure washers, and other small engines that sit between seasons.
A case suits anyone treating multiple tanks across vehicles, watercraft, and yard equipment, or keeping stabilizer on hand year-round. If you only winterize one or two engines, the single 10 oz bottle may be enough.
