SINGAPORE- * Japanese refiner Fuji Oil bought 750,000 barrels of Murban crude for loading in September at 35-40 cents a barrel below its official selling price (OSP), wider discounts than the previous month, trade sources said on Tuesday

* Ample supplies of light crude in Asia depressed the spot differential for Murban, the sources said

* The refiner bought less Murban crude this month because of high inventories and as it continues to lift Iranian crude in September, one of the sources said

* Last month, Fuji Oil bought 1 million barrels of Murban at 21-22 cents a barrel below its OSP for August loading
