Item
      4.01    Other Events.
(a)
      On
      September 19, 2006, the general partner of United States Oil Fund, LP (the
      "Registrant") dismissed Eisner LLP ("Eisner") as the Registrant's independent
      registered public accounting firm. The decision to dismiss Eisner was approved
      by the Audit Committee of the Board of Directors of the general partner of
      the
      Registrant.
The
      Registrant was organized on May 12, 2005 and commenced operations on April
      10,
      2006. As a result, 2005 was the only fiscal period for which an independent
      accountant's report has been provided on audited financial statements of the
      Registrant. Eisner's audit report on the Registrant's financial condition as of
      December 31, 2005 did not contain an adverse opinion or a disclaimer of opinion,
      nor was it qualified or modified as to uncertainty, audit scope, or accounting
      principles.
During
      the period from May 12, 2005 to the date of this report,
there
have
      been no disagreements with Eisner on any matter of accounting principals or
      practices, financial statement disclosure, or auditing scope or procedure,
      which
      disagreements, if not resolved to the satisfaction of Eisner, would have caused
      it to make reference to the subject matter of the disagreements in connection
      with its report on the registrant's financial statement.
Furthermore,
      there were no "reportable events" as described in Item 304(a)(1)(v) of
      Regulation S-K. Eisner has been provided with a copy of the above disclosure
      and
has
      furnished a letter addressed to the
U.S.
      Securities and Exchange Commission
stating
      whether it agrees with such disclosure and if not, stating the reasons it
      disagrees. A copy of such letter from Eisner dated September 19, 2006 is
      attached as Exhibit 16.1 to this report.
(b)
      On
      September 19, 2006, the general partner of the Registrant engaged Spicer
      Jeffries LLP ("Spicer Jeffries") as the Registrant's new independent registered
      public accounting firm to audit the Registrant's financial statements. The
      decision to engage Spicer Jeffries was approved by the Audit Committee of the
      Board of Directors of the general partner of the Registrant.
During
      the period from May 12, 2005 to the date of this report, the Registrant has
      not
      consulted with Spicer Jeffries regarding either (i) the application of
      accounting principles to a specified transaction of the Registrant, either
      completed or proposed, or the type of audit opinion that might be rendered
      on
      the Registrant's financial statements, or (ii) any matter that was either the
      subject of a disagreement, as defined in
Item
      304(a)(1)(iv) of Regulation S-K
,
      or a
      reportable event,
as
      described in Item 304(a)(1)(v) of Regulation S-K.
(d)
      Exhibits.
Exhibit
      16.1 Letter from Eisner LLP dated September 19, 2006 addressed to the U.S.
      Securities and Exchange Commission.
