STA-BIL® Storage Essentials are fuel stabilizers and protective treatments designed to prevent engine damage during off-season storage. This collection protects against fuel degradation, internal corrosion, rust, and pump freeze damage. For lawn mowers, boats, motorcycles, generators, and pressure washers, so equipment starts trouble-free after months of sitting.
Fuel starts degrading in as little as 30 days. Left untreated, it forms gum and varnish that clog carburetors, damage fuel lines, and turn a simple spring start into an expensive repair.
STA-BIL Storage Essentials covers the whole system. Fuel stabilizers keep gas fresh for up to 24 months. Fogging oil prevents internal corrosion. Rust Stopper shields exposed metal. Pump Protector keeps pressure washer pumps from freezing and cracking.
Family-Owned and trusted for over 65 years. Your equipment will be ready when you are.

Most storage damage is invisible until spring. By then, degraded fuel has gummed up carburetors, humidity has caused water in the fuel, and corrosion has formed. Here’s how STA-BIL stops it before it starts.
Lawn mowers, generators, and chainsaws sit for months between uses. STA-BIL keeps fuel fresh and carburetors clean so they start on the first pull when you need them.
Boats face a harsh combination of ethanol fuel, humidity, and long off-seasons. STA-BIL Storage and Fogging Oil work together to protect fuel systems and internal components through the whole winter.
Pump freeze damage is the most common off-season failure for pressure washers. STA-BIL Pump Protector winterizes the system in a single application.
STA-BIL has been America’s most trusted fuel stabilizer since 1958. Millions of engines rely on our products every storage season.
The makers of STA-BIL also have fuel treatments to fix non-running engines, remove water, and keep engines healthy when not in storage.
Keep engines running clean during active use
Prevent fuel line freeze in cold weather
Rough-running engines after long-term storage
STA-BIL Storage keeps fuel fresh for up to 24 months when added to fresh gasoline and stored in proper conditions. For best results, fill your tank at least 95% full before adding the stabilizer, then run the engine for five minutes to circulate the treated fuel through the entire system.
Use 1 oz of STA-BIL Storage for every 2.5 gallons of gasoline. For small engine equipment, add STA-BIL to your gas can before filling—that way every piece of equipment you fuel is automatically treated.
No. STA-BIL eliminates the need to drain fuel before storing your equipment. Just add the correct amount to a full tank of fresh gas, run the engine for five minutes, and store. This protects the entire fuel system, including carburetors and fuel injectors.
