100LL Avgas Market Analysis in Kentucky
We track 100LL avgas at 10 FBOs across 9 airports in Kentucky. The cheapest 100LL is $5.61/gal at Co-Mar Aviation (KBWG), and the highest is $8.72/gal — a $3.11/gal difference depending on where you stop. 6 FBOs are below the $7.08/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $73 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.
