Marathon Ashland Petroleum Advises Customers of 1Q Maintenance

Marathon Ashland Petroleum Advises Customers of 1Q MaintenanceFINDLAY, Ohio, Jan. 23 /PRNewswire-FirstCall/ -- Marathon Ashland Petroleum LLC (MAP), owned 62 percent by Marathon Oil Company, a wholly owned subsidiary of Marathon Oil Corporation (NYSE: MRO), and 38 percent by Ashland Inc. (NYSE: ASH), is advising its customers that it expects to meet their needs while scheduled refinery maintenance projects occur in the first quarter.

Overlapping, planned maintenance projects, including investments in the "Tier 2" ultra-low sulfur gasoline production upgrades, will reduce MAP's 935,000 barrel-per-day crude oil capacity such that it expects to process about 775,000 barrels per day of crude oil in the first quarter of 2004.

"We want our customers to know that meeting customer needs was our first priority while planning this heavier than normal turnaround schedule," said Gary R. Heminger, MAP president.

Based in Findlay, Ohio, MAP is the nation's sixth largest refiner with 935,000 barrels-per-day capacity in its seven-refinery system. MAP's retail marketing system comprises approximately 6,000 locations in 15 states, more than half of which are Marathon brand locations. MAP serves the Midwest and Southeast as a petroleum products marketer with 86 light product and asphalt terminals and access to about 8,000 miles of pipeline.
