Which of the following is an additive blended into JP-8 fuel?

• A. Static dissipation additive
• B. Corrosion Inhibitor / lubricity enhancer
• C. Fuel System Icing Inhibitor
• D. Lubricating Oil Additive

Answer: (B)

A key idea is that aviation fuel like JP-8 is treated with additives to protect the fuel system and keep it reliable. The additive that is blended into JP-8 to serve both corrosion protection and lubricity is the corrosion inhibitor / lubricity enhancer. Corrosion inhibitors form a protective film on metal surfaces inside the fuel system and help neutralize contaminants, while lubricity enhancers reduce friction and wear on pumps, valves, and injectors. This combination is essential for maintaining component life and preventing fuel-system damage in varying conditions.

Lubricating oil additives, by contrast, are for engine oil, not the fuel. Static dissipation additives and fuel system icing inhibitors are also used in JP-8, but the option describing a corrosion-inhibiting and lubricity-improving blend best captures the additive typically blended into the fuel.
