ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

On June 25, 2003, the Audit Committee of the Board of Directors of CITGO
Petroleum Corporation ("CITGO"), pursuant to its powers, selected KPMG LLP
("KPMG") as the independent accountant of CITGO, effective immediately, and
replaced Deloitte & Touche LLP ("D&T") as its independent accountant. KPMG is
the current independent accountant for Petroleos de Venezuela, S.A., CITGO's
ultimate parent.

D&T's report on the consolidated financial statements of CITGO for the years
ended December 31, 2001 and 2002 contained no adverse opinion or disclaimer of
opinion and was not qualified or modified as to uncertainty, audit scope or
accounting principles. However, such report included an explanatory paragraph
relating to the accounting for the contribution to CITGO of the capital stock of
VPHI Midwest, Inc., which was formerly a wholly owned subsidiary of PDV America,
Inc., CITGO's immediate parent.

In connection with D&T's audits of CITGO's consolidated financial statements for
the years ended December 31, 2001 and 2002 and through June 25, 2003, the date
of cessation of the CITGO and D&T audit relationship, there have been no
disagreements with D&T on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of D&T, would have caused
them to make reference thereto in their report on CITGO's consolidated financial
statements. Further, no "reportable events," as defined in Item 304(a)(1)(v) of
Regulation S-K promulgated by the Securities and Exchange Commission , occurred
during the years ended December 31, 2001 and 2002 or during the subsequent
interim period through June 25, 2003.

CITGO requested that D&T furnish it with a letter addressed to the Securities
and Exchange Commission stating whether or not it agrees with the above
statements. A copy of such letter, dated June 30, 2003, is filed as Exhibit 16
to this Form 8-K.
