100LL Avgas Market Analysis in Minnesota
We track 100LL avgas at 8 FBOs across 7 airports in Minnesota. The cheapest 100LL is $6.75/gal at St. Paul Flight Center (KSTP), and the highest is $9.99/gal — a $3.24/gal difference depending on where you stop. 6 FBOs are below the $8.03/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $64 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.
