Which statement is true regarding AVGAS labeling for reciprocating-engine fuel fillers?

• A. It must display the word AVGAS and the minimum fuel grade
• B. It must display the word Jet Fuel
• C. It must display the word AVGAS only
• D. It must display the color blue

Answer: (A)

For reciprocating-engine fuel fillers, the labeling must clearly identify the fuel type and specify the minimum grade to use. This helps prevent misfueling with turbine fuel and ensures the correct gasoline grade is poured. Saying AVGAS tells you the fuel is aviation gasoline, and including the minimum grade (such as 100LL) communicates exactly which grade is acceptable, reducing the chance of using the wrong grade. Labeling something as Jet Fuel would be misleading, since Jet Fuel is for turbine engines, not reciprocating engines. Just displaying AVGAS without the grade would omit important information, and the requirement isn’t about color—color alone isn’t a regulatory substitute for the grade and type labeling.
