Exhibit 15.01

August 13, 2002

Premcor Inc.
1700 East Putnam Avenue
Suite #500
Old Greenwich, CT 06870

We have made a review, in accordance with standards established by the American
Institute of Certified Public Accountants, of the unaudited interim financial
information of Premcor Inc. and subsidiaries for the three-month and six-month
periods ended June 30, 2002 and 2001, as indicated in our report dated August 5,
2002 (which report includes an explanatory paragraph relating to the Company's
change in accounting method related to stock-based compensation issued to
employees). Because we did not perform an audit, we expressed no opinion on that
information.

We are aware that our report referred to above, which is included in your
Quarterly Report on Form 10-Q for the quarter ended June 30, 2002, is
incorporated by reference into Registration Statement No. 333-87210 on Form S-8.

We also are aware that the aforementioned report, pursuant to Rule 436(c) under
the Securities Act of 1933, is not considered a part of the Registration
Statement prepared or certified by an accountant or a report prepared or
certified by an accountant within the meaning of Sections 7 and 11 of that Act.

Yours truly,



DELOITTE & TOUCHE LLP
