What color is the 80/87 Avgas grade?

• A. Red
• B. Green
• C. Blue
• D. Purple

Answer: (A)

In aviation fueling, color coding helps prevent misfueling by letting you recognize the fuel grade at a glance. Each AVGAS grade is dyed a distinct color, so operators can quickly tell which fuel is in a container or dispenser. For the 80/87 grade, the dye used is red. This lower-octane fuel is intended for engines that don’t require high octane, and using the wrong grade can cause knocking or engine damage, so the red color serves as a clear visual cue to avoid wrong fueling. Other, higher-octane grades are identified by different colors (for example, blue and green), which is why red is the correct color for 80/87.
