Wyoming Gas Slips to $3.07 — Tiny Dip, Big Range at the Pump

Wyoming drivers caught a small break last week. Average gas prices fell 2.3 cents to $3.07 a gallon on Monday, according to GasBuddy’s survey of 494 stations statewide. It’s a modest move, but the spread at the pump is anything but: the cheapest station checked in at $2.68, while the most expensive hit $4.49 — a $1.81 gap.

How Wyoming stacks up

• Week over week: down 2.3¢ to $3.07

The US average slid 3.6¢ to $3.12. It’s 1.8¢ below a month ago and 2.8¢ below a year ago (based on 11M+ weekly price reports from 150k+ stations).
Diesel eased 2.6¢ to $3.658.

“Winter gasoline kicks in this week for most of the country, and if hurricane season stays quiet, I expect average prices to keep easing,” said Patrick De Haan, head of petroleum analysis at GasBuddy.

He flagged ongoing West Coast bumps tied to regional infrastructure issues.

Ten-year context (Wyoming avg on Sept. 15)

• 2024: $3.25 | 2023: $3.94 | 2022: $3.73 | 2021: $3.52
• 2020: $2.18 | 2019: $2.64 | 2018: $2.93 | 2017: $2.52
• 2016: $2.23 | 2015: $2.65

Crude & supply: WTI traded near $63 and Brent around $67 to start the week, little changed as markets weighed tighter OPEC+ additions and disruptions to Russian energy exports against signs of inventory builds.
EIA snapshot (week ended Sept. 5, 2025):

• S. crude inventories +3.9M bbl (about 3% below seasonal norms)
• SPR +0.5M to 405.2M
• Gasoline inventories +1.5M (near five-year seasonal average)
• Distillates +4.7M (about 9% below five-year seasonal)
• Refinery utilization up to 94.9%
• Implied gasoline demand fell to 8.51M bpd

Seasonal shift: The switch to cheaper winter-blend gasoline typically trims wholesale costs, giving retail prices room to slide — especially if storms don’t snarl Gulf Coast refining.

Quick hits

• Most common US pump price: $2.99
• Median US price: $2.95 (about 17¢ under the national average)
• Lowest average states: MS $2.68, OK $2.73, AR $2.75
• Highest average states: CA $4.64, WA $4.64, HI $4.45
• Biggest weekly movers: Oregon +21.5¢, Washington +20.7¢, Florida −16.4¢

Wyoming’s average is easing, but local variation is huge. With winter gasoline arriving and crude steady, odds favor a gentle drift lower into fall — assuming Mother Nature and refineries cooperate. In the meantime, shop around: the difference between the cheapest and priciest pumps in the state can easily buy you lunch.
