The average price for a gallon of self-serve regular gasoline in Bucks and Montgomery spiked 17.8 cents since last week, according to AAA’s Fuel Gauge Report.

That increase since last Monday is the most dramatic one-week spike in nearly two years, the report states. The price surge was largely the result of higher crude oil prices and the “rubber-banding” of midcontinent retail gasoline prices, which fell dramatically to end the year and are now swinging back up.

Locally, the price per gallon average is $3.670. The national average went up 16.9 cents  from a week ago to $3.533 and the Pennsylvania average increased 13.7 cents to $3.670.

In Bensalem, the cheapest price for regular is $3.63 at Vigilante Liberty at 1214 Bristol Pk.
