What readers paid for diesel in Oklahoma

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 Oklahoma 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 Oklahoma. The number above is Midwest (PADD 2), series EMD_EPD2D_PTE_R20_DPG, and it is the closest published federal figure for Oklahoma. We do not estimate a price for Oklahoma from it. 2 of Oklahoma'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 Oklahoma. The federal survey prices the district Oklahoma sits in, Midwest (PADD 2), at $6.480 per gallon in the week of October 26, 2026 (series EMD_EPD2D_PTE_R20_DPG), $0.13 above the US average of $6.352. Pump prices inside the district vary around that figure.

Off-road (dyed) diesel in Oklahoma

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

Temporary relief, 5 October 2026 to 2 February 2027: The Governor asked the Tax Commission, Department of Public Safety and Corporation Commission to pause dyed-diesel enforcement for 120 days for farmers, ranchers and agricultural and timber producers, and not to inspect or cite highway vehicles solely for dyed diesel. It is a request letter, not an executive order. (Governor's letter of 5 October 2026). Source
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.
44.3ca gallon of per-gallon tax skipped: 24.3c federal and 20.0c Oklahoma taxes and fees, though sales tax may apply instead (below).

Dyed diesel is exempt from Oklahoma's 19c diesel tax; suppliers deduct it on their monthly reports.

Penalty for highway use
State amounts not found in official sources.

Buying it
Bulk off-road users need a sales tax permit.

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.

Ask how a number on this page was built

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.
