FOR IMMEDIATE RELEASE:

May 2, 2003

                   CITGO Announces First Quarter 2003 Results

TULSA, Okla., -- CITGO Petroleum Corporation today reported net income of $140
million for the first quarter of 2003 compared with a net loss of ($16) million
for the first quarter of 2002. Operating income (income before interest and
income taxes) for the first quarter of 2003 was $243 million, compared with an
operating loss of ($7) million for the same period last year.

         Strong first quarter refining earnings resulted from strengthening
margins and steady operations. Additional factors include:

                  o        Gulf coast crack spreads doubled to $5.58 and Chicago
                           crack spreads were 75-percent higher at $6.45
                           relative to the crack spreads in the same quarter of
                           2002.

                  o        Crude oil differentials for sour, heavy sour and
                           Canadian crudes showed significant improvement in the
                           first quarter relative to the first quarter of 2002.

         While gasoline sales volumes held steady at three billion gallons when
compared to the first quarter of 2002, total refined product sales increased ten
percent to six billion gallons in the first quarter of 2003. In addition;

                  o        Gasoline sales to branded marketers and major
                           convenience store chains represented about 65-percent
                           of total gasoline sales, an increase of three percent
                           in the first quarter of 2003 relative to the first
                           quarter of 2002.

                  o        Wholesale margins on light oil products increased to
                           2.2 cents-per-gallon (cpg) in the first quarter of
                           2003 compared with 0.3 cpg in the first quarter of
                           2002.

                  o        Finished lubricant prices increased toward the end of
                           the quarter.

                  o        Finished lubricant volume was up nine percent in a
                           relatively flat demand market, reflecting the
                           strength of the CITGO/Mystik brands and successful
                           execution of the marketing plan.

                  o        Our asphalt refineries completed scheduled
                           turnarounds and are on target to produce and sell
                           asphalt for the 2003 paving season.

         Several first quarter market conditions positively contributed to
CITGO's overall financial results, including:

                  o        historically high refining margins driven primarily
                           by a reduction in worldwide refining capacity and a
                           heavy refinery maintenance schedule in the United
                           States;

                  o        historically low crude and products inventories; and

                  o        colder than normal winter weather, producing a strong
                           demand for distillate and improved distillate
                           margins.

         "With our refineries running at peak capacity throughout the quarter,"
stated CITGO President and CEO Oswaldo Contreras, "we were able to take full
advantage of robust refining margins and favorable market conditions that
existed during the last month and a half. Furthermore, our employees continue to
focus on 'keeping it safe, clean and running,' which directly contributes to
operational efficiency and the bottom line. On the marketing side, sales to
CITGO-branded marketers were up and wholesale margins improved significantly.

         "In addition to the above, we also worked to improve cash flow during
the quarter by implementing stringent cost control measures throughout the
corporation and securing additional financing to meet our operating needs When
taken all together, these factors added up to a good first quarter for CITGO,"
Contreras concluded.

         CITGO's executive team will conduct an investor conference call to
discuss first quarter earnings on Monday, May 5 from 1:30 PM to 3:00 PM (CDT).
Investors may access the call by dialing 1-800-553-0358.
