SINGAPORE, Sept 21 (Reuters) - Oil fell on Tuesday, resuming last week's trend and erasing part of the previous session's gain of 1.6 percent, on lingering worries about the U.S. economy ahead of a Federal Reserve meeting later in the day.
U.S. crude for October <CLc1> fell disproportionately to contracts further out, ahead of its expiry later on Tuesday. It lost 72 cents to $74.14 a barrel by 0635 GMT, while the November contract shed 34 cents to $75.85.
Oil on Monday tracked a global rally in equities, but gains came in thin trade ahead of the Fed meeting, with total contracts changing hands on the New York Mercantile Exchange (NYMEX) about 25 percent below the average volume over the last 30 days, according to Reuters data.
"The front month is heading to expiration date today, so liquidation is pressuring the market," said Tetsu Emori, a fund manager at Tokyo-based Astmax Co Ltd.
"The overall market is not very bad, reflected by the second-month contract. Equity markets are coming back and the sentiment of investors is getting better than before, heading into the FOMC meeting today."
The U.S. Federal Reserve is expected to tread water at a policy-setting meeting on Tuesday with a renewed promise to keep its portfolio from shrinking but no new steps to ease monetary policy. [
]"Risk appetite is reappearing. I think the Fed's statement will not be that negative," Emori said.
Japan's Nikkei average rose 0.6 percent on Tuesday, hitting a seven-week intraday high, with resource-related shares such as Mitsubishi Corp <8058.T> rising after oil, gold and other commodities rose the previous day. The S&P 500 <.SPX> hit a four-month high on Monday as Wall Street sought to extend a three-week rally. [

ICE Brent <LCOc1> for November dipped 23 cents to $79.09, trading more than $3 higher than the equivalent contract for U.S. crude. That premium had shrunk to less than $2 last week on expectations Midwest markets would tighten after a leak forced Enbridge to shut the biggest Canada-U.S. crude pipeline for more than a week.
"We would argue that Brent currently better reflects the situation in the global oil market, where consumption growth remains fairly robust," Credit Suisse analyst Stefan Graber, based in Singapore, said in a report.
China's apparent oil demand rose 8.2 percent in August over a year earlier, rebounding from July when refineries scaled back crude purchases and throughput from June peaks, Reuters calculations from official data showed on Tuesday. [
