100LL Avgas Market Analysis in Oklahoma
We track 100LL avgas at 13 FBOs across 10 airports in Oklahoma. The cheapest 100LL is $5.75/gal at McAlester Regional Airport (KMLC), and the highest is $7.59/gal — a $1.84/gal difference depending on where you stop. 7 FBOs are below the $6.63/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $44 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.
