Brent oil for May delivery was up 0.23% to $107.91 a barrel on the ICE Futures Exchange in London, while the spread between the Brent and U.S. crude contracts stood at $5.37 a barrel.

The EIA said total motor gasoline inventories decreased by 5.18 million barrels, compared to forecasts for a decline of 0.72 million barrels, while distillate stockpiles increased by 0.23 million barrels.
