Oil futures end slightly higher

Oil futures end slightly higher Thursday, finding support after the European Union a day earlier proposed a plan to wean itself off Russian crude over the next six months, though upside for the commodity was limited as the ICE U.S. Dollar Index traded near a 20-year high. West Texas Intermediate crude for June delivery rose 45 cents, or 0.4%, to $108.26 a barrel on the New York Mercantile Exchange. A stronger dollar can be a negative for commodities priced in the unit, making them more expensive to users of other currencies.
