The quest for lead-free aviation fuel has spurred advances in technology and environmental sustainability. This article presents a concise overview of aviation fuel evolution, primarily focusing on the search for alternatives to traditional-led Aviation Gasoline (AVGAS). Since the inaugural flight by the Wright brothers in 1903, avgas became integral to piston-engine aircraft, albeit with environmental concerns due to its lead content. Consequently, extensive research has pursued cleaner fuel options to mitigate lead emissions' environmental and health hazards. Numerous studies have explored potential substitutes for avgas, including mogas, alcohol-based additives, and fuel blends, aiming to maintain aircraft performance while reducing or eliminating lead content. Recent investigations have assessed the effects of different fuel processes on aircraft performance and emissions. High-octane mogas (RON 98) has emerged as a promising alternative to replace leaded avgas, showcasing its potential as a viable solution. Despite progress, further research is essential. Pursuing cleaner aviation fuel requires balancing performance optimization and environmental sustainability. Continued exploration and experimentation are crucial to identifying optimal solutions meeting aviation standards while ensuring a safer, greener future for air travel
