We track 100LL avgas at 10 FBOs across 9 airports in South Carolina. The cheapest 100LL is $7.23/gal at Beach Aviation Services (KMYR), and the highest is $9.81/gal — a $2.58/gal difference depending on where you stop. 6 FBOs are below the $8.12/gal state 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.
