Full listing title: STA-BIL 360 Marine Fuel System Treatment, 32 oz
Rated from the listing's specs, no buyer reviews yet
What it's made for: gas that sits in the can between storms.
Two fuel stabilizers close to it on our rating, each with a dated price.
The size the listing states. The dose per gallon is on the label; a snow blower burns only a few gallons a season, so even a small bottle lasts.
Stabilize: a 32 oz bottle, per the listing. Dose the can when you fill it, then run the engine a few minutes so treated gas reaches the carb.
Run it dry: some manuals say to run the tank empty for summer instead. Yours decides, and it's worth reading that page before April.
The seller states, word for word, in the STA-BIL 360 Marine (32 oz) listing:
Cleanses the entire fuel system using PEA additives, including fuel injectors, lines, & fuel pumps.
Run the engine for 5 minutes to treat the entire fuel system.
For specific storage needs, use our STA-BIL storage fuel stabilizer product.
The seller's words, quoted as written; we haven't checked them. Your manual and the model plate decide whether it fits.
At the price on Oct 30, 2026, each ounce works out at about $0.67 (price ÷ stated ounces, our arithmetic). That puts it in the cheaper third of the 6 fuel stabilizers we have a price and a stated size for.

Our take
The STA-BIL 360 Marine (32 oz) is about a 32 oz bottle, and it doesn't pretend to be more. No buyer reviews yet, so the STA-BIL 360 Marine (32 oz) has to win you over on paper. Our main reservation: it keeps fresh gas fresh, but it can't rescue fuel that has already gone stale. We'd pick it if your machine sits with gas in it for weeks at a time; otherwise, put it next to the STA-BIL Fuel Stabilizer (1 Gallon) first.
Before the STA-BIL 360 Marine (32 oz) ships, check your manual: the 32 oz bottle only helps if your manual says to stabilize for summer rather than run the tank dry.
Read the ratio on the label and add it to the can, not the tank, so it mixes properly.
Some makers want the tank stabilized for summer, others want it run dry. Our summer storage guide covers both.
Stabilizer keeps fresh gas fresh. It doesn't bring stale gas back.
How the STA-BIL 360 Marine (32 oz) stacks up against the closest alternative, the STA-BIL Fuel Stabilizer (1 Gallon).
| Criterion | STA-BIL 360 Marine, 32 oz | STA-BIL Fuel Stabilizer, 1 Gallon |
|---|---|---|
| Our rating | 6.0/10 | 6.3/10 |
| Size | 32 oz | 1 gal |
Pick the STA-BIL Fuel Stabilizer (1 Gallon) if you want our higher-rated option (6.3/10).
We rate it 6.0/10 (fair). The rating comes from its documented listing alone, as no customer-review record is captured yet.
Only if your manual agrees. A listing that names a long list of compatible machines is the seller's claim, not proof of fit: match the part number in your operator manual before you order.
Its listing states a 32 oz bottle. These are the seller's figures, not our measurements: whether it fits your exact machine is worth confirming first.
Dose: read the ratio on the label and add it to the can, not the tank, so it mixes properly. Your manual: some makers want the tank stabilized for summer, others want it run dry. Our summer storage guide covers both. Fresh gas: stabilizer keeps fresh gas fresh. It doesn't bring stale gas back.
