Note: Data on this table represents total crude oil capacity not gasoline, distillate production, diesel fuel production or production of other products. Capacity numbers do not change or often vary year to year. Production potential varies depending on time of year and status of the refinery. A rule of thumb is that roughly 50 percent of total capacity is gasoline production (about 1.0 million barrels of gasoline - 42 million gallons - is produced per day).

Utilization Rate Explanation: The utilization rate represents the rate at which crude oil is being processed. Utilization rates are calculated by dividing volume of crude inputs by crude refining capacity.
