What readers paid for diesel in New Mexico

Prices readers report from the pump: what they paid, where, and how they paid. Each one is a single fill on the date shown, not a survey average; the weekly EIA figures elsewhere on this page are the survey.

No reader has reported a price in New Mexico yet. Yours would be the first.

What did you pay for diesel?

Tell us the price at your last fill and see how it compares with the government survey for your state. Your report goes on this site as a dated reader report; we publish your state and the first three digits of your ZIP, nothing else.

No account, no email. Prices far outside the usual range for your state are checked before they appear. See our privacy policy.

Read this as a district figure, not a state figure. The EIA weekly on-highway diesel survey prices the United States, its districts and California, and nothing else. It does not price New Mexico. The number above is Gulf Coast (PADD 3), series EMD_EPD2D_PTE_R30_DPG, and it is the closest published federal figure for New Mexico. We do not estimate a price for New Mexico from it. 1 of New Mexico's neighbouring states sit in the same district and therefore show the same price below.

EIA does not publish a weekly on-highway diesel price for New Mexico. The federal survey prices the district New Mexico sits in, Gulf Coast (PADD 3), at $5.951 per gallon in the week of October 26, 2026 (series EMD_EPD2D_PTE_R30_DPG), $0.40 below the US average of $6.352. Pump prices inside the district vary around that figure.

A petroleum products loading fee of up to about 1.9c a gallon also applies, set by tier; New Mexico does not publish which tier is current, so it is not included.

Checked 22 October 2026 against New Mexico TRD, Combined Fuel Tax. Local and county taxes are not included. The percentage is against the EIA figure shown above, which is a district figure unless New Mexico is surveyed directly.

Off-road (dyed) diesel in New Mexico

Red-dyed diesel is the same fuel as clear diesel, sold without highway fuel taxes for uses off the public road. How New Mexico treats it, checked 25 October 2026. Rules for every state are on the off-road diesel guide.

Federal: dyed diesel skips the federal diesel tax except 0.1c. IRS news release IR-2026-122 (14 October 2026) waives federal penalties for highway use of dyed diesel from 1 October 2026 to 31 December 2026; state rules below still apply.
New Mexico fuel tax on dyed diesel
New Mexico's statute text on dyed diesel could not be checked; the Taxation and Revenue Department says only that its 21c special fuels tax has some deductions.
Sales tax
Gross receipts tax appears to apply: a legislative committee considered a gross receipts tax deduction for dyed diesel in September 2026, which implies there is none now.
Who may use it
Not confirmed; federal rules apply.
Penalty for highway use
Not found in an official source.
Roadside testing
Not confirmed.
Buying it
Not confirmed.

EIA publishes no diesel price for 49 of the 50 states on this site, California being the exception; those pages show the EIA district figure and say so. State taxes checked against each state's revenue department or statute on 22 October 2026 (sources in the tax breakdown above). Actual pump prices vary by retailer and location.

Every figure on this site is read out of a published federal survey, which means there is always a real answer to where it came from. Send the question and a person reads it. Answers name the table, the series and the survey week, so you can go and look at the same row we did.

Where a question shows up a gap, the answer goes onto the page it came from as well as into the reply. If your question and its answer would be useful to other drivers we may publish an anonymised version, and we ask you before we do.
