SAN FRANCISCO (MarketWatch) -- Crude-oil and gold futures tempered their gains Tuesday after a report showing that activity in the services sector rose in September. Crude oil for November delivery added 54 cents, or 0.7%, to $82 a barrel on the New York Mercantile Exchange. Before the report, crude futures sold at $82.21 a barrel. Gold for December delivery added $14.40, or 1.1%, to $1,331.20 an ounce, just a tad below earlier levels. Oil perked up immediately after the Institute of Supply Management data but then traded lower. The ISM reported a rise to 53.2 from 51.5 in August for its nonmanufacturing index.
