* US summer driving season may reduce inventories
* Market eyes possible move by Opec to boost world supplies

"Crude oil remained under pressure as the market remained focused on the discussion between Opec members about whether they should increase production later this year," ANZ said in a note.
"In the US, the data also presented a gloomy picture. Crude oil production rose to another record, while drilling activity picked up again."
