100LL Nationwide Average Hits $7.69, With Wide Regional Spread

Fuel-price data released this week put the national average for full-service 100LL at $7.69 per gallon. The figures show meaningful variation by region rather than a flat national rate. Alaska sits at the high end, with full-service fills averaging more than $11 per gallon. For owners routing trips or planning fuel stops, the spread underscores how much location alone can move the cost of a fill-up.
