NEW YORK, Aug 29 (Reuters) - Oil prices gained on Friday on concerns about the threat Tropical Storm Gustav poses to U.S. energy infrastructure, helping slam U.S. equities, and the dollar rose as it headed toward its best month since 1992.
U.S. stocks fell more than 1 percent as Dell warned that companies are cutting back on technology spending worldwide and economic data added to market jitters before a long U.S. Labor Day weekend.

The Nasdaq Composite Index < > was down 37.63 points, or 1.56 percent, at 2,374.01.But shares in Europe rose, and differing views about the pace of inflation in Europe and the United States sent the price of government debt in opposite directions.
Slowing regional inflation in Europe led two-year euro zone government bond prices to rise, reducing the chance for an interest rate hike, while concerns about rising inflation in the United States pushed U.S. Treasury debt prices lower.
The U.S. dollar gained against the euro after a report showed business activity in the U.S. Midwest expanded at a far more robust rate than expected as new orders jumped.
A separate report showed U.S. consumer confidence rose to its highest in five months in August. The large recovery from depressed levels was helped by moderating energy prices, and added to optimism surrounding the surging dollar.
The reports follow data earlier in the week showing greater-than-expected U.S. economic growth in the second quarter and strong durable goods orders for July.
The dollar rose against major currencies, with the U.S. Dollar Index <.DXY> up 0.33 percent at 77.385. But against the Japanese yen, the dollar <JPY=> was down 0.67 percent at 108.73 from a from a previous session close of 77.021.

"Again, this stands out as robust relative to what is seen in Europe and sends a now familiar signal of U.S. manufacturing competitiveness, notably relative to Europe," said Alan Ruskin, chief international strategist at RBS Greenwich Capital in Greenwich, Connecticut. in a note to investors.
Data showed euro zone consumer prices grew at a less-than-expected 3.8 percent annual clip this month, down from an all-time peak of 4 percent in July.
The European Commission's survey of inflation expectations among consumers, which plunged 22 points in August from 30 in July, provided more good news on inflation ahead of a European Central Bank meeting next week.
But data showed economic sentiment in the single currency bloc fell to 88.8 points this month from 89.5 points in July, below economists' expectations of a fall to 89.1 points.
"For the ECB, the decline in headline inflation and inflation expectations is good news," said Holger Schmieding, an economist at Bank of America. "The apparent fall of the euro zone economy into semi-stagnation or worse also supports market expectations that the ECB will cut rates eventually."
Dell Inc's <DELL.O> comments about technology spending sparked fears of weakness in the whole tech sector, as did the company's surprisingly steep fall in quarterly profit. Shares of the world's second-largest computer maker fell 12 percent.
Shares of companies sensitive to higher fuel costs, such as retailers and airlines, tumbled as oil rose above $118 a barrel. Gustav was poised to enter the Gulf of Mexico, raising concerns about its impact on U.S. offshore oil and gas output.

> index of top European shares closed 0.3 percent higher at 1,194.73 points. The index advanced 1.2 percent for the month, marking only the second month of gains among the past 10.Energy companies braced for Gustav, shutting down production and evacuating personnel from offshore rigs in the Gulf of Mexico, home to a quarter of U.S. crude oil production and 15 percent of its natural gas output.
In energy and commodities prices, U.S. light sweet crude oil <CLc1> rose 55 cents, or 0.48 percent, to $116.14 per barrel,, and spot gold prices <XAU=> fell $2.55, or 0.31 percent, to $830.70. The Reuters/Jefferies CRB Index <.CRB> was up 1.33 points, or 0.34 percent, at 394.68.
