100LL Avgas Market Analysis in California
We track 100LL avgas at 76 FBOs across 50 airports in California. The cheapest 100LL is $6.71/gal at Bishop Airport (KBIH), and the highest is $13.84/gal — a $7.13/gal difference depending on where you stop. 50 FBOs are below the $8.40/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $85 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.
