Which factor is affected by the API gravity of a fuel?

• A. Color grading.
• B. Storage planning and separation effectiveness.
• C. Odor intensity.
• D. Packaging size.

Answer: (B)

API gravity measures how dense a liquid is relative to water: higher API gravity means a lighter liquid, lower API gravity means a heavier one. That density difference is what governs how fuel behaves when stored and interacted with water and sediments. In storage and handling, you design tanks, separators, and settling systems around how the fuel and water will separate and where the interface will form. Heavier fuels tend to settle differently and may carry more solids, while lighter fuels float and can form water-in-fuel emulsions, affecting how easily water is removed. So API gravity directly influences storage planning and separation effectiveness. Color, odor, and packaging size are influenced by other factors and design choices, not by API gravity.
