HONG KONG, May 19 (Reuters) - Asian shares hit a new four-month high on Monday as a relentless rise in oil prices bolstered resource shares, but wariness about inflation and doubts about the U.S. economy kept gains in check.
The dollar was range-bound after its drop on Friday when data showing a plunge in U.S. consumer confidence to a 28-year low raised doubts about when the U.S. Federal Reserve will raise interest rates in the world's largest economy.
Asian shares have rebounded 20 percent since hitting the year's low in mid-March, but record oil prices continue to worry, despite the benefit to resource firms, given the prospects of inflation at a time of slowing global economic growth.
"In the short run, you might say it's good for resources, but what I'd suggest is that the very high prices are, in fact, steadily and very meaningfully eroding demand," said Angus Gluskie, portfolio manager at White Funds Management in Sydney.
"Ultimately, that's not going to provide a pretty picture."
The MSCI broad measure of Asian stocks outside Japan <.MIAPJ0000PUS> rose 0.5 percent by 0203 GMT, after earlier hitting its highest level since mid-January. However, that is still down about 5 percent down for the year.
The index breached the key psychological 500-point level on Friday, extending a recovery since mid-March on hopes the worst of the credit crisis has passed and that earnings in Asia will prove more resilient than expected.
Gains in Asian stocks on Monday were driven in large part by resource firms such as Sydney-listed Woodside Petroleum Ltd <WPL.AX>, though the overall advances were moderate.

Concerns over tight fuel supplies led oil prices higher, with U.S. light crude for June delivery <CLc1> up 33 cents at $126.62 a barrel, near the record $127.82 hit on Friday.
Oil prices have risen six-fold since 2002 and doubled since last year as strong demand from China and other developing nations comes amid tightening production capacity.
"The (oil) market still has a bullish leaning because of a weak dollar and fuel supply concerns," said Sydney-based David Moore, a commodity analyst at the Commonwealth Bank of Australia.
Gold also rose, with spot prices <XAU=> up at more than $903 an ounce against $899.55 late in New York on Friday, when prices of bullion jumped above $900 to its highest level in three weeks, tracking higher oil prices and a weaker dollar.
