The average price of a gallon of gasoline this week continued to march steadily to $3 a gallon. In some parts of the country, it's above that already.

On Friday the average price of a gallon of regular across the U.S. was almost $2.98, according to AAA, Wright Express and Oil Price Information Service. That's up 2 cents from Monday and 10 cents more than a week ago. Drivers on the West Coast pay an average $3.21 a gallon. Gas is about $3.09 a gallon in New England, $3.05 in the Mid-Atlantic states, $2.98 around the Great Lakes and $2.82 in the Southwest.

The rising price of oil has pushed up gasoline prices. Crude has climbed about 5 percent in the past 10 days, and on Tuesday it topped $90 for the first time in over two years. On Friday, benchmark oil lost 58 cents to settle at $87.79 a barrel on the New York Mercantile Exchange.
