* Oil above $115 as lower U.S. dollar spurs buying interest
* Analysts expect gasoline stocks drawdown, poll shows
* Venezuela eyeing output cuts to prevent further price falls
By Seng Li Peng
SINGAPORE, Aug 20 (Reuters) - Oil prices edged up to above $115 a barrel on Wednesday, as a lower U.S. dollar rekindled buying in oil and other commodities.
U.S. crude <CLc1> rose half a percent or 56 cents to $115.09 a barrel, while London Brent crude <LCOc1> climbed 45 cents to $113.70 a barrel at 0323 GMT.
"There could be further upside, but it will not be that much because of the poor economic outlook (in the West)," said Gerard Rigby of Fuel First Consulting in Sydney.
The dollar struggled to extend its gains against the euro, which fell to a six-month low on Tuesday, as traders look beyond evidence of a euro zone growth slowdown for any signs the European Central Bank would consider cutting interest rates.
An index that measures the dollar's performance against a basket of six major currencies was nearly flat at 76.745, slipping from a new high for the year of 77.413 <.DXY> hit on Tuesday. [

]The market expects a drawdown in gasoline stocks for the fourth-straight week as U.S. imports fall, a Reuters poll showed.
On average, the poll called for a 900,000 barrel increase in crude stocks, recovering from a larger-than-expected drawdown the week before, while gasoline stocks were forecast to show a 3 million barrel drawdown [
]."If the stocks drop, I expect crude prices to rise but it will be within the $118-$120 a barrel range. If the stocks increase, or are flat, I expect prices to be around the $112-$113 a barrel level," Rigby said.
Prices are unlikely to go below $100 a barrel in the short term because robust demand in China and India will help offset bearish sentiment in the West, he said.
Additionally, Organization of the Petroleum Exporting Countries (OPEC) member Venezuela will be proposing an oil production cut at the next OPEC meeting in September in Vienna if prices continue to fall, energy minister Rafael Ramirez told Reuters on Tuesday. [
]"That is why we won't see prices falling below $112 a barrel," Rigby said.
SUPPLY THREATS REMAIN
Political upheaval in producer countries and the threat of bad weather in the Gulf of Mexico would continue to underpin crude markets.
