Hawaii's extreme prices stem from total geographic isolation — all refined fuel must be shipped thousands of miles across the Pacific Ocean. The state has only one refinery, which recently faced capacity issues. County surcharges vary by island. Maui and the Big Island consistently pay more than Oahu.
