Gas prices in Missouri

Read this figure as regional, not state. The EIA weekly retail survey does not price Missouri. Everything below uses Midwest (PADD 2), the federal district Missouri sits in, and says so wherever the number appears. We do not estimate a price for Missouri from it.
Midwest (PADD 2), EIA weekly retail
$3.85/gal regular
$5.57/gal diesel

EIA does not publish a weekly retail gasoline price for Missouri. The federal survey prices the district Missouri sits in, Midwest (PADD 2), at $3.85 per gallon in the week of August 31, 2026, 22 cents below the US average of $4.07. Pump prices inside the district vary around that figure.

On-highway diesel for Midwest (PADD 2) is $5.57, 3 cents below the US diesel average of $5.60. EIA runs the diesel survey for California and the regions only, so every other state carries its district figure here. Excise steps up on a fixed annual ramp; residents can claim the tax back on proven non-highway use.
