AAA: Ore. gasoline price up again, rising 6 cents

PORTLAND, Ore. (AP) -- Gasoline prices are still rising in Oregon, but not so rapidly as the week before.

The AAA auto club says its survey this week shows the average price up six cents, to $3.57.

That's three cents below the national average. Last week the state average jumped 16.5 cents.

The AAA says a spike that began in mid-January has raised the national average for 25 consecutive days.

The organization cites several reasons for the spike: Speculators betting on rising prices in coming months, higher crude prices and refinery shutdowns and the switch from cheaper winter-blend gasoline to the cleaner burning but more expensive summer fuel.
