CASPER, Wyo. — A month-long slide in Natrona County’s average gas price ended in the past week as the average ticked upward a penny as the national average dropped by the same amount.

The nation’s average price of gasoline rose, then fell, and remains just below its week-ago level at $3.13 per gallon, according to GasBuddy data. The national average is up 3.1 cents from a month ago and down 43 cents from a year ago.

The national average price of diesel fell 3.2 cents in the last week to stand at $3.476 per gallon.

“While the national average didn’t fall quite as far as anticipated for Memorial Day, it was still one of the most affordable since 2021 — and, when adjusted for inflation, among the cheapest in nearly a decade,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “As we move into the heart of summer, I believe we’re likely to see a relatively stable stretch for gas prices as refinery maintenance wraps up. Don’t expect the national average to rise above $3.30 per gallon, nor drop much below $3 for now.

“While refining issues on the West Coast are beginning to ease, several factors could still influence prices in the weeks ahead — including growing uncertainty around the upcoming hurricane season. We’ll also be watching OPEC+’s meeting this week to see if they boost oil production again for July as well.”

On Monday, AAA reported that the national average price for a gallon of regular gasoline is $3.17, up 4 cents from last week. In Wyoming, the average is $3.14, down 1 cent. Natrona County’s average rose 1 cent to $2.84, giving the county the cheapest gasoline in the state for eight weeks in a row.

Laramie and Goshen counties continue to leapfrog each other week to week, jockeying to offer the second and third cheapest averages. Laramie County’s 9-cent drop last week brought its average to $2.94, now the state’s second cheapest average, while Goshen County’s price dropped 1 cent to $2.99, ranking it as the third cheapest, according to AAA.

The cheapest fuel in Natrona County on Tuesday was $2.69 at Exxon, 1968 E. Yellowstone Highway, followed by $2.75 at multiple gas stations in Casper, according to GasBuddy reports.

OIL PRICES
Ahead of a key OPEC+ meeting where the organization will be weighing another potential production increase, oil prices remained in the low $60 per barrel range as of Tuesday morning. WTI crude was off 62 cents to $60.95 per barrel, down from $62.08 last week, while Brent crude oil was down 54 cents to $64.20 per barrel, down slightly from last Monday’s $64.91 per barrel fetch. While OPEC+ may resort to raising production again, oil markets were also digesting the possibility of President Trump sanctioning Russia for escalating its attacks on Ukraine in recent days, which could impact oil markets, depending on the degree of any potential move. However, with OPEC+ potentially raising oil production, oil markets may see little overall impact.

OIL AND REFINED PRODUCT SUPPLIES
The EIA’s Weekly Petroleum Status Report for the week ending May 16, 2025, showed U.S. oil inventories rose by 1.3 million barrels, about 6% below the seasonal average for this time of year, while the SPR rose 800,000 barrels to 400.5 million. Gasoline inventories rose by 0.8 million barrels and stand 2% below the five-year seasonal average, while distillate inventories rose 0.6 million barrels and are about 16% below the five-year seasonal average. Refinery utilization rose 0.5 percentage points to 90.7%, while implied gasoline demand, EIA’s proxy for retail demand, fell 150,000 bpd to 8.644 million barrels per day.
