What is the shelf life of e85?

E85, a fuel blend of 85% ethanol and 15% gasoline, typically has a shelf life of around 3 to 6 months when stored properly. Over time, ethanol can absorb moisture and lead to phase separation, which can affect performance. It's best to use E85 within this timeframe to ensure optimal quality and avoid issues with engine performance. For long-term storage, keeping it in a cool, dry place in a sealed container can help extend its usability.
