What drivers in New Mexico are paying this week
New Mexico does not have a published weekly statewide average, so the reference number above is the Gulf Coast (PADD 3) average of $3.702. That regional benchmark fell $0.080 week over week and is $0.567 below the national average of $4.269. Stations in New Mexico typically trade within roughly 20 to 40 cents of the regional figure, depending on distance from the nearest terminal and local taxes.
New Mexico is a low-tax state, but its prices run above the Gulf Coast benchmark because fuel has to be trucked long distances from Texas and from the state’s own refineries in the Four Corners area.
Why New Mexico gas prices land where they do
- Low state fuel tax.
- Long truck routes from Texas refineries raise delivered cost.
- Three refineries in the northwestern part of the state supply local markets.
These are structural factors, not daily noise. They explain why New Mexico tends to sit in the same part of the national price range week after week, even when the national average moves. For the general mechanics behind these forces, see our guide on how gas prices are set.
How New Mexico compares
Neighboring states with a published weekly average give the clearest picture of the regional spread. The table below compares New Mexico against those states and the national average.
| Market | Regular price | vs New Mexico | Week change |

| New Mexico | $3.702 | — | −$0.080 |
| Texas | $3.632 | −$0.070 | −$0.070 |
| Colorado | $4.458 | +$0.756 | +$0.180 |
| U.S. average | $4.269 | +$0.567 | −$0.010 |
Ways to spend less on gas in New Mexico
- Membership warehouses such as Costco, Sam’s Club, and BJ’s usually price 10 to 30 cents below nearby branded stations.
- Stations a few miles off the interstate are often cheaper than the first exit, because they pay less for land and rely on local traffic.
- Apps that show station-level prices are worth using for the last mile — our numbers give you the regional baseline, they give you the address.
- Keeping tires at the recommended pressure and removing roof racks can recover 3 to 6 percent of fuel economy, which is worth 10 to 20 cents a gallon at current prices.

How we source New Mexico prices
Every figure on this page comes from the U.S. Energy Information Administration's weekly retail gasoline survey, which reports average retail prices in dollars per gallon including taxes. We rebuild the page every week after the survey is released, so the date on the price panel always matches the data behind it. We do not estimate missing state numbers; where the EIA does not publish a statewide series, we label the regional benchmark instead. Full details are in our methodology and data sources pages.
The bottom line for New Mexico drivers
At the regional benchmark of $3.702 per gallon, a 12-gallon fill-up in New Mexico costs about $44.42. Over a 15,000-mile year at 28 MPG, that implies roughly $1983 in fuel, before any local station discounts.
New Mexico gas price FAQ
What is the average gas price in New Mexico right now?
The U.S. Energy Information Administration does not publish a weekly statewide retail average for New Mexico. The closest official benchmark is the Gulf Coast (PADD 3) average, which was $3.702 per gallon for the week ending Oct 26, 2026. Local station prices in New Mexico typically fall within roughly 20 to 40 cents of that regional figure.
Is gas cheaper in New Mexico than the national average?
New Mexico is compared against the Gulf Coast (PADD 3) benchmark rather than a statewide number. The region averaged $3.702 versus the national average of $4.269, so New Mexico stations are best described as tracking below the national figure.
Why are gas prices low in New Mexico?
Low state fuel tax. Long truck routes from Texas refineries raise delivered cost. Three refineries in the northwestern part of the state supply local markets. These factors matter more than the national average in determining what local stations charge, because fuel markets are regional, not national.
Where can I find the cheapest gas in New Mexico?
Station-level pricing is not part of the EIA dataset, so we do not publish a cheapest-station list. In practice, the lowest prices in New Mexico are usually at membership warehouses, at high-volume stations on secondary roads rather than interstate exits, and at stations in lower-cost suburban counties. Use a station-level price app for the final address and our New Mexico benchmark to judge whether the price you see is reasonable.
Will gas prices go down in New Mexico?
Nobody can forecast a specific week with confidence. What can be said is mechanical: New Mexico prices follow crude oil costs, regional refining capacity, seasonal fuel specifications, and local taxes. When crude falls and refineries run normally, prices usually follow within two to four weeks. When a refinery goes down or a hurricane threatens the Gulf Coast, the move can reverse within days.
