EIA does not publish a Hawaii gasoline price. The West Coast (PADD 5) Except California all-grades price was $5.167 a gallon on September 15, 2026. The weekly file does not include that series, so this is the monthly price. At 12,000 miles a year and 25 mpg, the index counts that as $2,480.16 a year. Those miles are our standard, not a Census figure, and every town in Hawaii shares this price.
