   MIAMI, FL (DTN) -- The Pacific Northwest sub-octane gasoline premium 
weakened sharply Thursday (6/18), declining by 16cts even as the underlying 
July NYMEX RBOB futures contract rose, amid continued weakness in regional 
gasoline market sentiment.

An offer was heard in the market at an 18cts premium to July NYMEX RBOB 
futures, bringing the Pacific Northwest sub-octane premium to a current 
indication of a 17.5cts premium, down 16cts from Wednesday's (6/17) last 
assessed value.

The product was last seen trading near this level on March 9, 2025, when 
Pacific Northwest sub octane regular gasoline traded at an 18.25cts premium, 
according to DTN data.

    

   Motor gasoline inventories in the PADD 5 region rebounded after a five-week 
decline, climbing by 700,000 bbl to 28 million bbl during the week ended June 
12, after increasing from 27.3 million bbl the prior week, the EIA's Weekly 
Petroleum Status Report showed Wednesday.

    

   Year-on-year, gasoline stocks in the region were 1.2 million bbl lower. PADD 
5 gasoline imports fell by 13,000 bpd to 96,000 bpd last week and were 73,000 
bpd lower compared with the same week last year, the EIA said.
