It’s trick and treat for Halloween gasoline prices. The treat: The price is now the lowest since December 2010.

The trick is determining how long that will last.

The average gas price in New Jersey is now $2.80 a gallon, said Tom Kloza, chief oil analyst at the Oil Price Information Service in Wall Township.

Drivers in the Philadelphia area are paying about $3.09 a gallon, while stations in Delaware are charging an average of $2.87.

Stay tuned, said Kloza.

“We may go a little bit lower,” he said, predicting prices could drop to $2.50 in New Jersey before bottoming out.

“We’ll bottom somewhere in November and December, and then move a little bit higher in the spring,” Kloza said.

Gas prices have dropped as crude oil price declined because of a larger supply and lower world demand.

Unless there’s some major geopolitical event, Kloza said motorists should not have to worry about $4 a gallon gasoline for the rest of the decade.
