100LL Avgas Market Analysis in Arizona
We track 100LL avgas at 20 FBOs across 14 airports in Arizona. The cheapest 100LL is $6.64/gal at Show Low Regional Airport (KSOW), and the highest is $9.10/gal — a $2.46/gal difference depending on where you stop. 8 FBOs are below the $7.99/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $67 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.
