Light sweet crude for May delivery, closed at 111.76, up 1.52 dpb compared with Friday's close, marking a record closing high.
London Brent for the delivery in May settled down 1.09 dollars at 109.84 dollars shortly after the contract broke through the 110-dollar barrier for the first time.
Brent oil briefly traded at a record 110.01 dollars before receding as the London market closed for the day.
Traders were forced by supply concerns in the United States, which is the world's biggest economy and the largest global consumer of energy.
The market was also boosted by the flagging US dollar. A weak US currency encourages demand for dollar-priced goods, such as crude oil, as it can make them more affordable for buyers holding other currencies.
Earlier Monday, prices had fallen due to expectations of a drop in worldwide crude demand after Group of Seven (G7) finance chiefs expressed deep concern over the US economy, analysts said.
