Tensions between Syria and Turkey gave oil prices their biggest jump in two months Thursday, while refinery outages boosted wholesale gasoline prices.

Oil settled at $91.71 per barrel, up by $3.57, or 4 percent, on the New York Mercantile Exchange. The rise follows a decline of 4 percent on Wednesday.

Wholesale gasoline futures jumped on that news. Gasoline in New York Harbor rose 14.34 cents, or 5.1 percent, to $2.943 per gallon.

The national average for a gallon of regular was $3.784, up two-tenths of a cent from Wednesday, and up 38 cents compared to a year ago, according to AAA.

But that small increase masks a sharp rise in gas prices in California. Gasoline prices had already risen on the West Coast since the Aug. 6 fire at a Chevron refinery in Richmond, Calif.
