LONDON, Sept 7 (Reuters) - Oil prices edged up above $68 a barrel in thin trade on Monday, with sentiment buoyed by Asian and European equities and by a decision by the G20 to keep economic stimulus measures in place.
U.S crude for October delivery <CLc1> rose 30 cents to $68.32 a barrel by 0805 GMT. London Brent crude <LCOc1> was up 32 cents at $67.14 a barrel.
Group of 20 finance leaders, who met in London on Saturday, said they would not end economic stimulus plans until the recovery was well entrenched, raising the prospect of higher fuel demand in coming months. [
]Along with U.S. data released late last week showing a slowdown in layoffs, the G20's decision helped lift Asian and European shares. [

"As the long Labor Day weekend comes to an end, we're looking at the end of peak gasoline demand season in the U.S., which means we're now entering a period of slack seasonal demand with refineries scaling back their runs," said Toby Hassall, a commodities analyst at CWA Global Markets in Sydney.
Oil prices, which fell 6.5 percent last week, have been trading in a range between $65 and $75 a barrel since the start of August, with prices swinging on economic data as investors seek clues about the speed of a recovery from the recession.
Oil came under pressure last week on concerns over the jobless rate in the United States, which hit a 26-year high, although the pace of layoffs slowed.
OPEC MEETING
Increased crude supplies from the Organization of Petroleum Exporting Countries (OPEC) due to slipping compliance, could also put downward pressure on oil prices in the near term, analysts said.
OPEC members meet in Vienna for a quarterly output policy meeting this week, with most analysts expecting the group, the source of more than a third of the world's oil supply, to maintain its official output target to keep prices stable around $70. [
]"We expect another OPEC quota rollover to be the result of the meeting; in addition, there will undoubtedly be calls for better quota compliance (i.e., lower production) from OPEC members such as Angola, Iran, and Venezuela," Societe Generale said in a research note.
