100LL Avgas Market Analysis in Michigan
We track 100LL avgas at 21 FBOs across 14 airports in Michigan. The cheapest 100LL is $6.20/gal at Elite Jet Center at Contact (KPTK), and the highest is $8.65/gal — a $2.45/gal difference depending on where you stop. 13 FBOs are below the $7.18/gal state average. For a typical 50-gallon piston top-off, the cheapest stop saves roughly $49 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.
