WTI crude was off 1.92 per cent, or 62 US cents, at $US31.66, after reaching a high of $US33.60.
Gold has risen for a second day, hitting three-month highs as the US dollar continued to ease amid mounting doubts that the US Federal Reserve will raise interest rates in 2016 due to global economic and financial headwinds.
Analysts have said dovish comments from New York Fed President William Dudley on Wednesday and recent weak US economic data have cast more doubt on the likelihood of a swift pace of Fed rate increases in 2016.
"The market is fetishising bad news and convincing itself that the Fed will never be able to hike again," director of base and precious metals trading for BMO Capital Markets in New York.
Higher US interest rates make non-yielding gold a less attractive asset.
Spot gold was up more than one per cent at $US1,155 an ounce at 2.20 pm EST (0620 Friday AEDT), after touching $US1,156.60 earlier in the session, its highest since October 29.
US gold futures for April delivery settled up 1.4 per cent at $US1,157.5 an ounce.

Spot platinum touched $US905.61, its highest since November 11, while palladium was up 1.05 per cent at $US517.75.52 after hitting a one-month peak of $US515.54 on Wednesday.
Zinc has climbed to its highest in more than three months on concerns about potential shortages, while a slide in the US dollar on worries about the US economy boosted copper and the wider industrial metals market.
Metals were buoyant as investors scrambled to close out bearish positions before the Lunar New Year holiday in China.
The closure of major zinc mines in late 2015 and the filing for Chapter 11 bankruptcy by US producer Horsehead this week highlighted concern over tightening supply.
London Metal Exchange three-month benchmark zinc surged to a peak of $US1,728 a tonne, the highest since October 29, before paring gains to close at $US1,715, a rise of 1.1 per cent.

"It's a good bounce but fundamentally unwarranted at this stage."
LME sister metal lead gained 0.5 per cent to finish at $US1,803 a tonne after touching a peak of $US1,829, the strongest since October 15.
