Gas prices in Nevada set a Labor Day weekend record this week. Las Vegas hit $4.90 a gallon on Thursday, Sept. 3, and the statewide average reached $4.91, both eclipsing the old Labor Day high of $4.82 set in Las Vegas in September 2022, according to AAA data reported by the Las Vegas Review-Journal.
The same day, AAA figures published by KOLO in Reno showed Reno drivers paying $5.18 a gallon, 28 cents more than Las Vegas and roughly 5.7% above it. Reno is also running about 25% above the national average of $4.14, compared with an 18% premium in Las Vegas. Neither city’s coverage mentioned the other’s price that day.
A Record That Beat 2022 by Eight Cents, Nationally by a Lot More
Las Vegas’s new record cleared the 2022 mark by only 8 cents, a 1.7% increase. The national record, by contrast, is being broken by a wider margin. The national average of $4.14 is about 8.4% above the prior Labor Day high of $3.82, set in 2012, and marks the first time the national average has topped $4 on the holiday, according to AAA.
Year over year, the increases are steep everywhere. Las Vegas prices are up $1.06 a gallon from a year ago, a 27.6% jump. The Nevada statewide average is up $0.98, a 24.9% increase, and the national average is up 95 cents, a 29.8% rise.
Those percentages are not stated in the underlying reports, which give only the dollar changes, but the direction is consistent: gas got roughly a quarter to nearly a third more expensive in the past year, whichever geography is measured.
Doug Johnson, a spokesperson for AAA Mountain West Group, tied the spike to crude oil, which has traded near $90 a barrel amid what he called “continued volatility in the Strait of Hormuz.” He added that “after a record-setting August, this Labor Day weekend is on track to also set a record at the pump.”
Las Vegas: $4.90 a gallon, up $1.06 from a year ago
Reno: $5.18 a gallon, the state’s highest metro price
Nevada statewide: $4.91 a gallon, up 98 cents from a year ago
National average: $4.14 a gallon, a record for Labor Day
Reno’s 28 Cent Premium, and the Pipeline Behind It
Reno drivers paying more than Las Vegas drivers is not new. In February 2025, Reno averaged $4.20 a gallon against $3.87 in Las Vegas, a 33 cent gap, according to Nevada News 3.
That means this week’s 28 cent gap has actually narrowed by 5 cents since then, even as both cities’ prices climbed by roughly a dollar a gallon over the same stretch. The premium has persisted through a year and a half of otherwise sharp price swings.
The reason has to do with infrastructure, not local demand. Nevada imports about 86% of its transportation fuel from California, and Southern Nevada draws that supply through two separate lines: Kinder Morgan’s CALNEV pipeline, which handles 90% of Southern Nevada’s fuel, and the HF Sinclair UNEV Pipeline, which brings roughly 15% of Nevada’s total fuel in from Utah, according to a January 2026 analysis from Nevada Current.
Reno has no such redundancy. It relies on a single line, Kinder Morgan’s SFPP North Line, to bring in gasoline and diesel from California.
That single-pipeline dependence leaves Reno more exposed when California supply tightens, which it has. Phillips 66 and Valero Energy have shut down refinery capacity in California equal to about 17% of the state’s total refining, per the same analysis.
A proposed extension of the UNEV Pipeline would add a second supply route into Reno from Utah, but as of the January 2026 report, it remained a proposal, not an operating line. Until it is built, Reno’s higher, more volatile prices are a function of geography, not a temporary anomaly.
How Nevada’s Two Regions Get Their Fuel
- CALNEV pipeline (Kinder Morgan): Carries roughly 90% of Southern Nevada’s gasoline and diesel in from California refineries.
- UNEV Pipeline (HF Sinclair): Brings about 15% of Nevada’s total fuel supply in from Utah refineries, a partial hedge against California disruptions.
- SFPP North Line (Kinder Morgan): Reno’s only pipeline connection for gasoline and diesel, also sourced from California.
- Proposed UNEV lateral to Reno: Would give Reno a second supply route from Utah, reducing its single-pipeline exposure. Not yet built as of January 2026.
- Statewide exposure: Nevada has no significant crude reserves, no major refinery of its own beyond limited asphalt production, and no emergency fuel storage, leaving the whole state dependent on California output.
The Same Week, a Record Travel Forecast
The price spike lands squarely on top of the Las Vegas Convention and Visitors Authority’s own Labor Day forecast, released the same week. The LVCVA is projecting 335,000 visitors over the three day weekend, up 4.4% from last year, and an estimated $703.2 million in economic impact, up 4.1%, according to the Las Vegas Review-Journal.
Hotel occupancy is forecast at 89.5%, and the average nightly rate for a Friday through Sunday stay is $269.66, up from $257.60 last year, a 4.7% increase.
Neither the tourism forecast nor the gas price coverage referenced the other. But the timing means Nevada’s tourism industry is forecasting its busiest, priciest Labor Day in years in the same week that reaching the state by car got measurably more expensive.
Diesel adds a second layer to that: Las Vegas diesel hit $6.08 a gallon this week, up $2.17 from a year ago, a 55.5% increase, roughly double the percentage jump in gasoline prices over the same period.
That matters beyond personal travel, since the freight trucks moving goods along I-15 into Southern Nevada and I-80 through Reno both run on diesel, not gasoline.
Gas price figures for Las Vegas, the Nevada statewide average, the national average, the 2022 and 2012 record comparisons, and the AAA quote are drawn from the Las Vegas Review-Journal’s Sept. 3, 2026 report and AAA’s own Labor Day fuel price release, also published Sept. 3, 2026. The Reno price figure is drawn from KOLO’s Sept. 3, 2026 report, also based on AAA data. The February 2025 Reno and Las Vegas comparison figures are drawn from Nevada News 3’s Feb. 20, 2025 report. Pipeline and fuel dependency figures are drawn from Nevada Current’s Jan. 20, 2026 analysis and are labeled with that date since they predate this week’s price data. The Labor Day visitor and economic impact forecast is drawn from the Las Vegas Review-Journal’s Sept. 3, 2026 tourism coverage. All percentage changes, the narrowing of the Reno to Las Vegas gap, the record margin comparisons, and the diesel to gasoline percentage comparison are original calculations for this article and are not stated in any of the underlying reports.
