100LL Avgas Market Analysis in Texas
We track 100LL avgas at 68 FBOs across 43 airports in Texas. The cheapest 100LL is $5.75/gal at City of Alice (KALI), and the highest is $10.39/gal — a $4.64/gal difference depending on where you stop. 36 FBOs are below the $7.91/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $108 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.
