Is STA-BIL 360 worth it over plain STA-BIL Storage?

360 Protection adds PEA cleaners and corrosion protection on top of storage stability. If you mainly store fuel, plain Storage is cheaper; if you also want to clean the fuel system, 360 does both.

How much fuel does one 32 oz bottle treat?

At 1 oz per 5 gallons, a 32 oz bottle treats up to 160 gallons. That covers several seasons for most mowers and generators.

Can I use it in a 2-cycle engine?

Yes. It is listed for 2-cycle engines and mixes into the fuel, so it works in chainsaws, trimmers and outboards.

Does it work with ethanol-blended gas?

Yes, it is formulated for ethanol and non-ethanol fuels. It does not reverse phase separation once water and ethanol have already split.

How long does it keep fuel fresh?

STA-BIL rates it for up to 12 months of stability. Treat fresh fuel and run the engine briefly so the treated gas reaches the carburetor.

When is the best time to buy it?

Prices tend to dip in fall and early spring around storage season. The current $10.97 at The Home Depot as of November 4, 2026 is already near the low end.
