Five other states reported averages below $3 a gallon, including neighboring Wyoming and Colorado, both at $2.92, and Idaho, $2.98 (Oklahoma and Minnesota were the other two).
In fact, according to the search website GasBuddy.com, a higher percentage of stations in the Rocky Mountain region have been selling gas at or below $3 for the past several days than any other area of the country.
Motorists can bless (or blame) the relentless cycle of supply and demand for the late Christmas present.
"We have high prices in summer and some of the lowest prices in the winter," said Rolayne Fairclough, spokeswoman for AAA Utah. "It has to do with demand going down. It's a traditional cycle that we usually see."
The region's lower prices also can be attributed to healthy gasoline inventories, the availability of cheap Canadian crude and refineries that operate exceptionally well, said Gregg Laskoski, senior petroleum analyst at GasBuddy.com.
On Tuesday, all of the Utah cities tracked by AAA reported price decreases of at least 45 cents month-over-month.
Salt Lake City and Logan saw the biggest declines, 56 cents. Ogden had the smallest, 45 cents.
Nationally, Tuesday's average of $3.30 a gallon was a cent higher than a week ago and only a nickle lower than a month ago.
"The Rockies region is doing very well, as they are insulated from the higher price of West Texas Intermediate crude oil and can capitalize on the less expensive crude from Canada," Patrick DeHaan, a GasBuddy.com analyst, said in a statement.
