From the Press Release:
A report commissioned by the Foundation for Taxpayer and Consumer Rights shows a sharply higher (and still growing) gap between crude oil prices and gasoline prices — and between pump prices in California and the rest of the nation. The study, conducted by oil analyst Tim Hamilton, finds that Californians are paying $7 to $15 per fill-up more than the rest of the nation, with gasoline prices stuck at 40 cents to 55 cents a gallon above the U.S. average.
Because the costs of making gasoline are relatively stable, the disconnect between oil and gasoline prices amounts to a bottom-line bonanza for oil companies, the report concludes.
