Brent crude futures fell $1.48, or 1.41%, to $103.84 a barrel by 0426 GMT. U.S. West Texas Intermediate crude futures slipped $1.39, or 1.36%, to $100.63 a barrel.
Both contracts settled over 30 cents higher in the previous session due to ongoing concerns about tight worldwide supply, and another drawdown in U.S. distillate and gasoline stocks.
