SEOUL (Aug 28): Crude oil futures rose on Friday, adding to their biggest one-day rally in over six years the day before, led by recovering equity markets and news of diminished crude supplies.

The corresponding crude options market, however, remained muted on Thursday, suggesting most big traders were shrugging off the move as merely a correction in the year-long bear market.
