Benchmark oil fell $3.30 to $83.04 per barrel Friday in New York after earlier dropping to $82.56 per barrel. The slide added to a 17 per cent plunge in May.

The reports on jobs and manufacturing are the latest signals that the U.S. economy is growing more slowly.

U.S. employers added 69,000 jobs in May, the government said, which is the smallest number in a year and far short of the 158,000 new jobs expected by economists. The unemployment rate rose to 8.2 per cent from 8.1 per cent in April.
Economic news from China and Europe contributed to oil's plunge Two new surveys show that manufacturing slowed in May in China, which is a huge importer of oil and other commodities. Some analysts said the surveys suggest China's economic growth will fall below 8 per cent in the second quarter which could curb the need for imports. The U.S. and China are the world's two biggest consumers of oil.
Meanwhile, unemployment across the 17 countries that use the euro remained at 11 per cent in April, which was the highest level since the single currency was introduced back in 1999, according to a new report.
