Des Moines Gas & Diesel Watch: AAA prices ease for regular, diesel ticks up (July 7)

Price as of 7/7/26: AAA’s Des Moines metro averages show regular unleaded at $3.506/gal (down from $3.532 yesterday) while diesel is $4.179/gal (up from $4.155).

Regular gas: easing vs. yesterday, higher than a week ago

For regular in the Des Moines metro, AAA lists $3.506/gal today. That’s lower than yesterday’s $3.532, but still above last week’s $3.440. Looking further out, regular is $3.741 versus last month and $2.946 versus last year.

Diesel: up vs. yesterday (and still the bigger swing)

AAA puts diesel at $4.179/gal as of 7/7/26—above yesterday’s $4.155. Diesel is also higher than last week’s $4.044 and last year’s $3.541, while remaining below the month-ago level of $4.667.

Bottom line: today’s move is another reminder that regular and diesel don’t always travel together—diesel is the cost that’s most likely to swing day-to-day for fuel-reliant operations.

What that can mean locally

• Commuters and weekend drivers: regular is slightly cheaper than yesterday, but the longer-run picture is still mixed.
• Delivery, trades, and service businesses: diesel’s uptick matters for route planning and budgeting when fleets fill throughout the week.
• Contractors and logistics: if you track both fuels, keep them separate—today shows a clear divergence.

National context (EIA)

Separately, EIA’s July 7, 2026 gasoline and diesel update reports that U.S. regular gasoline and on-highway diesel are down versus the prior week. Local prices can still move differently than the national direction.
