100LL Avgas Market Analysis in South Carolina
We track 100LL avgas at 11 FBOs across 9 airports in South Carolina. The cheapest 100LL is $6.96/gal at Vantage Aviation (KGMU), and the highest is $9.54/gal — a $2.58/gal difference depending on where you stop. 7 FBOs are below the $7.82/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $43 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.
