Why this matters

E10 absorbs moisture in humid climates. Phase-separated fuel destroys injectors and carburetors.

No regrets: Fuel older than 30 days in a vented tank deserves stabilizer — or a fresh fill before storage.

When DIY is not enough

Hard starting, sputtering, or water in the separator after layup needs fuel-system service — not another can of additive. Winterization and spring commissioning include structured fuel treatment.

DIY steps

Buy from high-turnover marinas when possible.
Add manufacturer-recommended fuel stabilizer before any layup over two weeks.
Fill the tank to reduce condensation headspace (unless your storage protocol says otherwise).
Label the date you treated the tank on your winterization checklist.
