This project was completed in the interest of comparing the current aviation gas (avgas) in use to a variety of unleaded options. The reason the industry needs unleaded avgas is because the lead that is in the current gas is harmful when inhaled and causes a variety of diseases and illnesses, and is degrading to our environment. The industry has been pushing for an unleaded alternative for a couple years now, and there are now a few options available. This paper explores a couple of those alternatives and compares the engine and emission data to determine if any of these chosen fuels have the potential to replace the current avgas.
