The price of a barrel of crude oil held at more than $94 Monday, but prices were headed lower a day after a deal was made with Iran on its nuclear program.
The agreement among Iran and six world powers allows a partial lifting of sanctions put in place to thwart Iran's suspected nuclear weapons ambitions.
The deal does not lift sanctions on oil exports, but traders view it as a step in that direction because improved relations with Iran could result in fewer export restrictions.
On the New York Mercantile Exchange, crude oil shed 68 cents to $94.16 per gallon. Reformulated blendstock gasoline dropped more than 4 cents to reach $2.6842 a gallon. Home heating oil dropped 0.92 cents to reach $3.0321 per gallon.
Natural gas picked up 3 cents to $3.80 per million British thermal units.
At the pump, the national average price of unleaded gasoline rose slightly, climbing from Sunday's $3.275 per gallon to $3.28, the AAA Daily Fuel Gauge Report said.
