Item 7.   Financial Statements, Pro Forma Financial Information and Exhibits.

          c.  Exhibits

              99.1    The Lubrizol Corporation News Release dated July 22, 2003

Item 9.   Regulation FD Disclosure

          The following information is being furnished pursuant to Item
          12 "Disclosure of Results of Operations and Financial
          Condition," and is included under this Item 9 in accordance
          with the procedural guidance in SEC Release No. 33-8216.

          A copy of the press release dated July 22, 2003 announcing the
          Company's results for the three months ended June 30, 2003, is
          attached as Exhibit 99.1 to this Current Report on Form 8-K

          The Company believes that disclosure of earnings per share
          data excluding the current year restructuring charge and the
          effect of the prior year accounting change is useful to
          investors because it depicts operating results excluding these
          items and may provide the investor with a better base from
          which to make future projections.

                                    SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
