Why are jet fuels more susceptible to water contamination than aviation gasoline?

Jet fuel is more susceptible to water contamination primarily due to its chemical composition and properties rather than viscosity. Jet fuel, specifically Jet A and Jet A-1, is composed of hydrocarbons that have a different affinity for water compared to aviation gasoline.

One key aspect is that jet fuels have lower volatility and a different molecular structure, making them more susceptible to water absorption. While viscosity can play a role in how fluids interact, it is not the main factor in the susceptibility to water contamination in this context.

The correct answer would highlight that jet fuels' properties, such as their chemical structure and the presence of certain additives, influence their interaction with water more significantly. Aviation gasoline generally contains additives that help mitigate contamination and has a formulation designed to minimize water interaction, keeping it relatively more stable against water contamination compared to jet fuel.
