Can gasoline left in a car for a year still be used?

[LeCourtney]

Gasoline left for a year cannot be used. Generally, it should not be stored for more than three months. Judging gasoline quality by color: Transparent or translucent light yellow is the ideal color for gasoline. If the color is too dark, it indicates the gasoline contains more impurities such as sulfur. The stronger the gasoline smell, the worse the quality. If a strong gasoline odor or even an irritating smell is noticeable immediately upon opening the bottle cap, it suggests the gasoline is of poor quality with excessive sulfur content. Methods to identify gasoline quality: Vehicles that consistently use genuine national standard gasoline may produce unusual noises after running for a while with blended gasoline. After using blended gasoline, the vehicle's exhaust emissions may change compared to normal, appearing whiter or darker, or having an abnormal odor. Normal gasoline should appear clear and transparent, with a light or even colorless hue. Gasoline that is cloudy, whitish, or dark in color may have quality issues.
