100LL Avgas Market Analysis in Mississippi
We track 100LL avgas at 10 FBOs across 10 airports in Mississippi. The cheapest 100LL is $6.00/gal at Magnolia Airworks LLC (KMCB), and the highest is $7.72/gal — a $1.72/gal difference depending on where you stop. 5 FBOs are below the $6.96/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $48 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.
