Asian differentials for May-lifting Middle East crude fell on Tuesday due to ample supplies and soft demand, traders said.
Traders said some sellers still have May-lifting Middle East crude cargoes unsold, although most Asian refiners have covered their spot requirements.
Differentials for benchmark Oman fell to minus five to plus seven cents to its official selling price set by the Ministry of Oil and Gas, down from MOG plus three to eight cents on Monday.
The market heard a Japanese trading house sold a May-lifting cargo at MOG minus one cent a barrel on Monday, and about two sellers each have one May-lifting Oman cargo unsold.
Differentials for May-lifting Murban and Qatar Marine also fell, as sellers were heard having difficulty finding buyers.
