Fresh-gasoline storage treatment
Measure using the Storage formula rate
Choose package quantity by fuel volume
The 10 oz gasoline storage stabilizer contains enough additive for up to 25 US gallons of fresh gasoline at the published rate. This is total package capacity across treatments, not a single-tank instruction. Seasonal equipment often remains unused with fuel still in the system. A gasoline storage fuel stabilizer is intended for that storage-planning task, helping limit fuel deterioration and gum or varnish formation when used as directed. Add it to fresh fuel rather than relying on it to restore fuel that is already badly degraded.
Choose a package by the amount of gasoline you intend to treat over time. The treatment rate is different from the Marine formula and from diesel treatment, so measure using this product’s own directions. A larger container provides more additive; it does not change the dose or extend the stated protection period.
Before lay-up, check the fuel type approved for the equipment and follow the engine manufacturer’s storage procedure. Fuel-system treatment and internal engine preservation are separate maintenance tasks. A stabilizer is not a reason to skip other required storage steps or to use an otherwise unapproved fuel blend.
Keep a record of the treatment date, amount of fuel and measured additive. Reclose the container according to its label after use. Compare package sizes using current prices and your planned fuel quantity rather than assuming the entire container belongs in one tank.

What Customers Say
Perfect size for small boat winterization
Bought the 10oz STA-BIL bottle (MPN 22206) to treat my outboard engine before storing it for the season. Mariners Warehouse delivered it quickly and properly sealed. Engine started right up in the spring with no issues.

Ethanol gas ruins small engines if left untreated. This 10oz stabilizer keeps gasoline fresh and protects the fuel system from gum and varnish buildup. Very fast fulfillment from the seller.

Always keep a 10oz bottle handy for backup gas cans and seasonal equipment. The dosing chamber on the bottle makes measuring exact amounts super simple. Excellent customer service.
Effective product, convenient squeeze top
Treats up to 20 gallons of fuel, which is perfect for my lawnmower and small watercraft. Keeps the fuel fresh for over a year. Shipping took an extra couple of days, but the product performance is top notch.
Keeps stored fuel fresh for up to 24 months
Used this in my emergency standby generator tank. After sitting for 10 months, the fuel was still clean with zero dark oxidation or sediment. High quality product and great store experience.
