100LL Avgas Market Analysis in Alabama
We track 100LL avgas at 11 FBOs across 10 airports in Alabama. The cheapest 100LL is $6.50/gal at ALair Jet Center (KANB), and the highest is $8.70/gal — a $2.20/gal difference depending on where you stop. 4 FBOs are below the $7.74/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $62 versus the average.
100LL is the standard fuel for most piston-engine aircraft. Because avgas volumes are smaller than Jet-A, prices are especially sensitive to local supplier logistics and airport traffic. Self-serve pumps usually undercut full-service by a wide margin and are often available 24/7. Figures update daily from AirNav reports.
