ITEM 5. OTHER EVENTS

         Tesoro Petroleum Corporation ("Tesoro" or "the Company") is updating
certain supplemental financial and operational data for both the fourth quarter
and year ended December 31, 2001 through the Company's website. The Company's
website is located at www.tesoropetroleum.com. This website data is filed as
Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by
reference.

         Tesoro issued a Press Release on January 30, 2002 announcing its
earnings for the fourth quarter and year ended December 31, 2001 and its capital
spending plans for 2002. The Press Release is filed as Exhibit 99.2 to this
Current Report on Form 8-K and is incorporated herein by reference.

         The information provided may contain forward-looking statements and
certain assumptions upon which such forward-looking statements are in part
based. This information should be read in conjunction with Tesoro's filings with
the Securities and Exchange Commission ("SEC"), as well as with other
publicly-disclosed information, such as media releases and conference calls. The
Company expects that updates to the website information will be made through its
periodic reports filed with the SEC and public releases; however, the Company
undertakes no obligation to update any information contained on the website.

         Numerous important factors, including those factors identified as Risk
Factors and Investment Considerations and Forward-Looking Statements in Tesoro's
Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other of the
Company's filings with the Securities and Exchange Commission, and the fact that
the assumptions set forth in the website data and Press Release could prove
incorrect, could cause actual results to differ materially from those contained
in such forward-looking statements.
