The price of oil is rising the most in two months after tensions rose between Syria and Turkey.
Oil rose to $91.36, a jump of $3.22, or 3.7 percent, in afternoon trading on the New York Mercantile Exchange.
Thursday's rise follows a decline of 4 percent on Wednesday.
The increase came as Turkey's military fired on targets in Syria for the second day. Prices also got a boost from a falling dollar, which tends to influence investors to buy commodities like oil and gold.
The price of gasoline at the pump rose two-tenths of a cent, to $3.784 for a gallon of regular, according to AAA. That's up 38 cents from a year ago.
Brent crude, which is used to price international varieties of oil, was up $3.66, or 3.4 percent, to $111.83 in London.
Other energy futures traded in New York jumped as well:
-- Natural gas rose 4 cents to $3.43 per 1,000 cubic feet.
-- Heating oil advanced 10 cents, or 3.2 percent, to $3.17 per gallon.
-- Wholesale gasoline rose 12 cents, or 4.2 percent, to $2.92 per gallon after reports of a fire at an Exxon Mobil Corp. refinery.
