Regular gas: $3.6520/gal in the latest AAA Missouri average

Diesel: $4.5200/gal in the latest AAA Missouri average

National context (EIA): gasoline and on-highway diesel also higher week-over-week

EIA’s weekly data show the bigger picture isn’t just Missouri. In its latest week-over-week comparison, U.S. regular gasoline retail was up 7.8 cents/gal, and U.S. on-highway diesel retail was up 21.8 cents/gal. Drivers in Goodman-area commutes, and anyone who runs vehicles for work, should expect local station pricing to stay sensitive to that broader pressure.

Missouri taxes: part of what you pay at the pump

Missouri’s motor-fuel tax is embedded in the per-gallon price at purchase. The Missouri Department of Revenue notes that most receipts don’t list the motor fuel tax as a separate line item, but the tax is still included in the price per gallon—and calculated from the applicable rate based on the date of purchase.

What residents and local businesses should watch

For families budgeting weekly commuting costs, the statewide average uptick matters because it can pull up the baseline at area stations. Diesel increases can also ripple outward: they often show up in delivery and hauling costs that support local businesses, farm and service routes, and contractor schedules.
