Feb. 25 (Bloomberg) -- Nippon Oil Corp. will slash crude oil processing by 22 percent in March from a year earlier as a warmer-than-average winter reduces heating-oil demand.

The refiner will also trim output in February by 16 percent from a year earlier compared with a planned cut of 12 percent, a company spokeswoman said by phone from Tokyo. Nippon Oil will process 3.99 million kiloliters, or about 25.1 million barrels, next month, it said.
