Marathon Petroleum's large-scale refining system (including the Galveston Bay refinery in Texas City as the largest US refinery at 631,000 barrels/day) processes crude oil into gasoline, diesel, jet fuel, and specialty products distributed through branded Speedway (sold to 7-Eleven in 2021) and independent dealer networks and MPLX's logistics infrastructure.
