* Gold moves up on oil, weaker dollar
* Dollar off 8-month peak (Updates prices, adds quotes)

SINGAPORE, Aug 21 (Reuters) - Gold firmed on Thursday after oil gained more than $1 a barrel and spurred safe-haven buying, with a falling U.S. dollar offering extra incentives for speculators to buy.
Platinum gave up earlier gains as fears of falling demand for autocatalysts lingered, while chart-driven buying supported silver and palladium, dealers said.
Gold <XAU=> rose to $815.50/816.50 an ounce from $810.35/811.75 an ounce late in New York on Wednesday, when it advanced to its highest in nearly a week around $817 with the help of physical buying.
"I think gold is consolidating at the moment. I think it's a range market around $800 to $830 right now. But you know, the price is actually very volatile," said Dick Poon, manager of precious metals at Heraeus Ltd in Hong Kong.
Jewellers, which snapped up gold earlier this week after prices dropped to nine-month lows last week, were on the sidelines. "The customers are waiting for the price to get lower. They are buying on dips," said Poon.
Gold was well below a lifetime high of $1,030.80 struck in March.
U.S. crude futures <Clc1> rose to more than $116 a barrel on supply concerns after Russia expressed its displeasure over a U.S.-Poland missile shield pact. [
]In theory, expensive oil lifts gold's appeal as a hedge against inflation, while a weaker dollar makes bullion an attractive alternative investment to currencies and bonds.
The dollar index, which measures the dollar's value against a basket of six currencies, slipped 0.2 percent to 76.777 <.DXY>. It struck its highest level this year of 77.413 on Tuesday.
"Volume remains very thin because most people are on vacation. I suspect we might have already seen a short-term low of $773," said Peter Tse, a dealer at Scotia Mocatta in Hong Kong, adding the upsided was capped at $835 to $845.
"So it just plays with the range for the time being," he said.
Spot platinum <XPT=> fell to $1,363.00/1,383.00 an ounce from $1,368.50/1,388.50 an ounce late in New York but off Tuesday's 11-month low around $1,296 an ounce.
"I think it's a bit oversold earlier on but I don't think it could bounce back to the $1,500-$1,600 areas. It's quite difficult, so it's still consolidating for the time being," said Tse of Scotia Mocatta.
New York gold futures <GCZ8> added $5.0 an ounce to $821.20.
Gold sales by signatories of the Central Bank Gold Agreement could be the lowest since the pact was signed in 1999, the World Gold Council said on Wednesday. [
