100LL Avgas Market Analysis in Alabama
We track 100LL avgas at 10 FBOs across 9 airports in Alabama. The cheapest 100LL is $6.65/gal at Shelby County Airport (KEET), and the highest is $8.70/gal — a $2.05/gal difference depending on where you stop. 5 FBOs are below the $7.71/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $53 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.
