What type of fuel is primarily recommended for the Warrior PA-28A?

The recommended fuel for the Warrior PA-28A is Avgas 100LL, which stands for "100 octane low lead." This type of fuel is specifically formulated for aircraft engines and is essential for providing the proper performance and safety standards required for flying.

Avgas 100LL has a higher octane rating than the lower octane fuels, which helps prevent engine knocking and promotes smoother operation during flight. Using the correct fuel type is crucial for ensuring the engine operates efficiently and safely. The PA-28A's engine is designed to work most effectively with Avgas 100LL, providing optimal power output and engine reliability.

While other fuel types like Avgas 90LL, 110LL, and 130LL may exist, they do not meet the performance needs of the Warrior PA-28A as effectively as 100LL does. Using a fuel that does not meet the specific requirements of the aircraft can lead to decreased performance or potential engine issues. Thus, selecting Avgas 100LL is vital for the safe operation of the Warrior PA-28A.
