What readers paid for diesel in Hawaii

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 Hawaii 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 Hawaii. The number above is West Coast less California, series EMD_EPD2D_PTE_R5XCA_DPG, and it is the closest published federal figure for Hawaii. We do not estimate a price for Hawaii from it.

Hawaii is inside PADD 5 but every gallon arrives by tanker and county fuel taxes stack on the state rate, so the West Coast regional average understates island pump prices.

EIA does not publish a weekly on-highway diesel price for Hawaii. The federal survey prices the district Hawaii sits in, West Coast less California, at $6.614 per gallon in the week of October 26, 2026 (series EMD_EPD2D_PTE_R5XCA_DPG), $0.26 above the US average of $6.352. Pump prices inside the district vary around that figure.

Off-road (dyed) diesel in Hawaii

Red-dyed diesel is the same fuel as clear diesel, sold without highway fuel taxes for uses off the public road. How Hawaii 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.
Hawaii fuel tax on dyed diesel
Hawaii taxes diesel by use, not by dye: off-highway diesel pays 1c a gallon state tax and no county tax, against 32.5c to 40c for highway diesel. Farm equipment can claim back tax above 1c.
Sales tax
General excise tax of 4%, plus a 0.5% county surcharge (4.5% in every county).
Per-gallon charges dyed diesel still pays
Environmental response, energy and food security tax ($1.05 a barrel): 2.5c
Who may use it
Off-highway vehicles, stationary engines and boats.
Penalty for highway use
No Hawaii-specific dyed-fuel penalty found; fuel without an exemption certificate is taxed at the highway rate.
Roadside testing
No state programme found.
Buying it
Give the seller an exemption certificate for off-highway vehicle use; none is needed for stationary engines or boats.

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.
