Storing 2-stroke fuel without degradation: proven methods

Pump fuel lifespan

60-90 days max, less in summer. Bioethanol absorbs water, additives oxidize.

Methods to extend storage

1. Alkylate fuel (Aspen, MotoMix) — 3-5 years storage, no ethanol
2. Stabilizer (Sta-Bil) — extends pump fuel to 6 months
3. Metal sealed can — 500 days vs 60 in clear plastic
4. Cool storage — at 20°C normal, at 5°C × 1.5

Best combo: alkylate + metal can + cool = 2-3 years easy.
