FOR IMMEDIATE RELEASE:

           CITGO Announces 2004 Second Quarter and Six Months Results

TULSA, Okla., August 2, 2004 -- Luis Marin, CITGO Petroleum Corporation's
President and CEO, today announced second quarter net income of $172-million and
six months ended June 30 net income of $207-million. Net income during the
second quarter and first six months of the year exceeded that of the same time
periods in 2003 (excluding insurance recoveries) by $80-million and $51-million,
respectively. This outstanding performance in 2004 exceeded 2003 results
(excluding insurance recoveries) by 88-percent for the second quarter and
32-percent for the first six months of the year and also significantly exceeded
budgeted expectations.
     According to Marin, the company's outstanding performance was based on
employees' efforts in accomplishing the following:

- -        Strong cash flows permitted the repayment of the $200-million Senior
         Secured Term Loan prior to its maturity, which was scheduled for
         February 27, 2006. The $200-million Senior Secured Term Loan was
         supported by the Company's equity interests in Colonial and Explorer
         pipelines. Consequently, all of CITGO's remaining debt is unsecured and
         future interest expense will be reduced.
- -        CITGO was also successful in extending the maturities on $95-million of
         outstanding Letters of Credit supporting various tax-exempt industrial
         revenue bonds in the second quarter.
- -        The second of two new gasoline hydrotreaters was completed and brought
         on-line at the Lake Charles, La. refinery as part of the Tier II
         gasoline program. These units help produce the environmentally friendly
         gasoline that will aid in the improvement of air quality in CITGO's
         marketing areas.
- -        All of CITGO's refineries were recognized by the National Petrochemical
         & Refiners Association (NPRA), receiving multiple awards for
         outstanding safety performance.





- -        Utilization of our light oils refineries was limited to 84-percent in
         the first quarter due to an unusually heavy level of scheduled
         turnarounds. Following completion of the first quarter turnarounds,
         utilization in the second quarter increased to 99-percent, allowing us
         to take advantage of strong market conditions during the period and
         positioning us to take full advantage of market opportunities for the
         balance of the year.

- -        Overall, we had outstanding performance in the execution of our
         turnarounds, which were completed on schedule and on budget. Total
         turnaround expenses during the first half of the year, most of which
         were incurred during the first quarter, approached $80-million, which
         compares with a historical annual average of about $60-million.

- -        The capital spending in 2004 associated with the implementation of the
         Tier II environmental projects, the major expansion at Lake Charles,
         and the replacement of coker drums at Lake Charles continued on budget
         and on schedule.

     "With the strong foundation built in the first half of this year, we expect
continued improvement in our performance for the rest of 2004," concluded Marin.
