100LL Avgas Market Analysis in Louisiana
We track 100LL avgas at 15 FBOs across 10 airports in Louisiana. The cheapest 100LL is $6.85/gal at DaveAir, LLC (KMLU), and the highest is $9.98/gal — a $3.13/gal difference depending on where you stop. 7 FBOs are below the $8.25/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $70 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.
