Fresh-gasoline storage treatment
Measure using the Storage formula rate
Choose package quantity by fuel volume
The 16 oz gasoline storage stabilizer contains enough additive for up to 40 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
Essential for seasonal marine engine storage
I've been using this 16oz STA-BIL stabilizer in my boat's gas tank every off-season. Mariners Warehouse shipped it quickly and well-packaged. The engine fired up right away on the first crank after months of storage.
Keeps small engines running smoothly
Great product for treating gasoline in lawnmowers, generators, and outboard motors. Prevents gum and varnish build-up effectively. Great price on MPN 22207 from this store.
Reliable fuel treatment every time
I add this 16oz bottle to my stored fuel cans before winter hits. Never had an issue with stale gas or clogged fuel injectors. Fast delivery and excellent service.
Good formula, easy measuring top
The 16oz squeeze bottle makes it easy to measure out the exact dose needed. Works well for keeping gas fresh up to 24 months. Delivery took an extra day, but product is top quality.
Must-have for ethanol fuel protection
Prevents ethanol-blended fuel from deteriorating in storage. Used this in my jet ski and emergency generator. Zero starting issues come springtime. Highly recommend purchasing from Mariners Warehouse.
