Storage stability refers to the fuel's resistance against what?

• A. Degradation
• B. Color Change
• C. Oxidation In Air
• D. Freezing

Answer: (A)

Storage stability is about how well fuel keeps its quality over time in storage, resisting chemical changes that can alter performance. The best description is degradation, because degradation covers the broad range of chemical processes that reduce fuel quality—oxidation, polymerization, gum formation, sediment buildup, and changes in lubricity or viscosity—that can occur during storage. Color change can occur as a symptom of degradation but isn’t the defining measure of stability. Oxidation in air is a specific degradation pathway, not the overall concept. Freezing is a physical condition that affects flow or icing, not the chemical stability of the fuel during storage.
