CHEYENNE, Wyo. — This past week, the average price of gas for drivers in Laramie County increased in tandem with the national average.
Based on GasBuddy data, the average price in the country is $3.14 per gallon. The national average is 1.8 cents lower than it was a year ago and has not changed from a month ago.
Over the past week, the average price of diesel nationwide has risen by 0.7 cents to $3.665 per gallon.
According to Patrick De Haan, head of petroleum analysis at GasBuddy, “states that saw price cycling just ahead of the switch back to winter gasoline saw the majority of the slight increase in the national average last week.” “States with a history of regular price cycling, including Florida, Ohio, Michigan, and Maryland, experienced double-digit increases in average gas prices. Gas prices are under further downward pressure now that a large portion of the country has started switching to less expensive winter gasoline and as driving demand tapers off seasonally as temperatures drop.
“This fall, the national average is still on track to drop below $3 per gallon for the first time in years.”
The national average price for a gallon of regular gasoline is $3.18, according to AAA’s report on Monday. This represents a 1 cent increase from the previous week. The average in Wyoming is $3.12, which is also one cent more than it was the week before. A 7-cent increase to $2.98 per gallon moved Laramie County out of the top three cheapest averages and into fifth place.
For the fifth consecutive week, Natrona County’s average fuel price remained the lowest in Wyoming, dropping 7 cents to $2.74. With an average fuel price of $2.92, Albany County overtakes Laramie County to re-enter the top three cheapest averages. According to AAA, Campbell County dropped from second to third place with an 8-cent increase to $2.95 per gallon.
According to GasBuddy’s report, the cheapest gas in Laramie County right now is $2.85 at Sam’s Club, 1948 Dell Range Blvd., Moody’s Rock Stop, 901 W. Pershing Blvd., in Cheyenne, and Antelope Truck Stop, 3850 Interstate 80 in Burns.

OIL MARKET DYNAMICS
Oil prices have seen slight weakness over the last week but remain in the low-$60 per barrel range as the market continues to absorb additional OPEC production, while the Trump administration encourages Europe to cut the consumption of Russian energy. In early Monday trade, a barrel of WTI crude was down 70 cents to $61.98 per barrel, down from $63 last Monday. Brent crude was also in the red, down 60 cents to $66.08 per barrel, a slight dip from last Monday’s $67.17 per barrel start. “Oil prices are moderately down versus last week. The large US crude draw had a moderate positive effect last week, and based on low net crude imports, we might see another US crude draw this week,” said UBS commodities analyst, Giovanni Staunovo. “Prices suffered a bit from markets perceiving last week’s Fed cut as hawkish, and that weighed on market sentiment.”
