Gasoline prices are going up.

The average price for a gallon of gasoline in the United States rose nearly 12 cents in the past three weeks to about $3.51, due in part to higher prices for North Sea crude oil, according to the nationwide Lundberg Survey.

The national average for a gallon of regular gasoline rose 11.57 cents to $3.5101 as of February 10, the survey of about 2,500 gasoline stations in the continental United States found.

That was a greater change than the 3.5-cent rise in the previous survey, which covered the two weeks that ended January 20.

Survey editor Trilby Lundberg told Reuters that the higher prices came as the price for North Sea Brent crude rose more than $7 per barrel. Brent prices are more volatile and sensitive to changes in the Middle East than is U.S. crude.

I paid $3.65 last Friday at my usual spot in Palmetto Bay, and that was lower than a lot of places out on US 1, which is the main highway to the Keys from Miami; some places it was $3.83 and higher.

So what are you paying?
