SINGAPORE, Jan 5 (Reuters) - Saudi Aramco has raised February prices for most of the crude it sells to Asia and the United States, but cut prices in Northwest Europe and the Mediterranean.

The state oil giant said on Thursday that the price of Arab Light crude for Asian customers rose by $0.60 a barrel versus January to a discount of $0.15 a barrel to the Oman/Dubai average.

Prices for other crude grades to Asia were up by $0.40-$0.60 a barrel in February.

The price hikes were slightly higher than expected, three Asian traders said, coming on the back of possible supply cuts in February.

The company dropped its Arab Light OSP to Northwest Europe by $0.50 a barrel for February from the previous month at a discount of $4.70 a barrel to the Brent Weighted Average (BWAVE).

The Arab Light OSP to the United States was set at a premium of $0.25 a barrel to the Argus Sour Crude Index (ASCI) for February, up $0.20 a barrel from the previous month.
