                           FORWARD LOOKING STATEMENTS
 
     From time to time, the Company may make statements which constitute or
contain "forward-looking" information as that term is defined in the Private
Securities Litigation Reform Act of 1995 or by the Securities and Exchange
Commission in its rules, regulations and releases. The Company cautions
investors that any such forward-looking statements made by the Company are not
guarantees of future performance and that actual results may differ materially
from those in the forward-looking statements. The following are some of the
factors that could cause actual results to differ materially from estimates
contained in the Company's forward-looking statements:
 
     - The pattern of the Company's sales, including variations in sales volume
       within periods and sales to significant customers, which makes
       forward-looking statements about sales and earnings difficult and may
       result in the variance of actual results from those contained in
       statements made at any time prior to any given period's close;
 
     - The Company's ability to develop, produce and market new and innovative
       products and services on which future operating results depend. There are
       a number of risks inherent in these activities, including technological
       changes, manufacturing facility capacity, availability of raw materials
       and critical manufacturing equipment, changing customer needs and
       competitive reactions;
 
     - Vigorous competition within the Company's product markets, including
       pricing and promotional, advertising or other activities in order to
       preserve or gain market share in any segment, the timing and intensity of
       which cannot be foreseen;
 
     - Global or regional economic factors and potential changes in laws and
       regulations affecting the Company's various businesses in over 75
       countries around the world, including changes in product mix, currency
       exchange rate fluctuations, changes in monetary policy and tariffs, and
       federal, state and international laws regulating the environment, which
       could impact the Company's financial condition and results of operations;
 
     - The market price of the Capital Stock or other securities of the Company,
       which could be subject to fluctuation in response to quarterly variations
       in operating results, changes in analysts' earnings estimates, market
       conditions, press releases issued by the Company, and general economic
       conditions and other factors external to the Company, thereby affecting
       the availability of capital to the Company;
 
     - The impact of special charges resulting from ongoing evaluation of
       business strategies, asset valuations and organizational and corporate
       structures, and the implementation of restructuring plans, including new
       computer and logistics systems;
 
     - The costs, effects and liabilities associated with legal, regulatory or
       administrative proceedings and any required remedial action, anticipated
       or unanticipated;
 
     - Real estate costs and the Company's ability to negotiate effectively
       based on competitive factors, which could cause the number of new Q Lube
       facilities to differ from the number projected and could affect expenses
       in other segments; and
 
                                        3
   5
 
     - Significant competitive pricing pressures and intense competition for
       qualified, skilled employees, which could affect profitability,
       productivity and/or expenses.
 
                              SELLING STOCKHOLDERS
 
     The following table sets forth the name of the Selling Stockholders and (i)
the number of shares of Capital Stock owned by the Selling Stockholders as of

                              PLAN OF DISTRIBUTION
 
     The Offered Securities may be sold from time to time directly by the
Selling Stockholders. The Offered Securities may also be sold by the Selling
Stockholders in (a) ordinary brokerage transactions and in transactions in which
brokers solicit purchasers, (b) sales to a broker or dealer as principal and
resales by such broker or dealer for its own account pursuant to this Prospectus
or (c) in a combination of such methods of sale, at market prices and other
terms prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices. The Offered Securities may be sold on any
national securities exchange or automated interdealer quotation system on which
shares of Capital Stock are then listed, through negotiated transactions or
otherwise. Brokers, dealers and agents who participate in the sale of the
Offered Securities may receive compensation in the form of underwriting
discounts, concessions or commissions from the Selling Stockholders and/or
purchasers of the Offered Securities for whom they may act as agent. The Selling
Stockholders and any brokers, dealers or agents that participate in the
distribution of the Offered Securities might be deemed to be "underwriters"
within the meaning of the Securities Act, and any profit on the sale of such
Offered Securities and any discounts, commissions or concessions received by any
such brokers, dealers or agents might be deemed to be underwriting discounts and
commissions under the Securities Act. At the time a particular offer of any of
the Offered Securities is made by the Selling Stockholders, to the extent
required pursuant to the Securities Act, a supplement to this Prospectus will be
distributed which describes the method of sale in greater detail. In addition,
any Offered Securities which qualify for sale pursuant to Rule 144 under the
Securities Act may be sold under Rule 144 rather than pursuant to this
Prospectus.
 
     The Selling Stockholders will pay their costs and expenses of selling the
shares of Capital Stock offered hereunder, including commissions and discounts
of underwriters, brokers, dealers or agents, and the Company will pay the costs
and expenses incident to its registration and qualification of the Capital Stock
offered hereby, including registration and filing fees.
 
     The Selling Stockholders may indemnify any broker-dealer that participates
in transactions involving the sale of shares of Capital Stock against certain
liabilities, including liabilities under the Securities Act.
 
     There can be no assurance that the Selling Stockholders will sell any or
all of the shares of Capital Stock offered by them hereunder.
 
                                USE OF PROCEEDS
 
     The Company will not receive any of the proceeds from the sale of the
Offered Securities by the Selling Stockholders.

ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         There are incorporated herein by reference the following documents
filed by the registrant with the Securities and Exchange Commission (File No.
1-2677):

                  (a) The Company's Annual Report on Form 10-K for the fiscal 
         year ended December 31, 1997;

                  (b) The Company's Current Report on Form 8-K/A-2 dated

                  (d) The Company's Current Report on Form 8-K dated April 14,
         1998;

                  (e) The Company's Registration Statement on Form 8-A/A filed
         with the Commission on April 21, 1998; and

                  (f) The description of the Company's Capital Stock contained
         in the section entitled "Description of Capital Stock" contained in the
         Company's Current Report on Form 8-K filed with the Commission on

         purpose of updating such description.

         All documents subsequently filed by the registrant pursuant to Sections
13(a), 13(c), 14 or 15(d) of the 1934 Act subsequent to the filing of the annual
report on Form 10-K referred to in (a) above and prior to the filing of a
post-effective amendment which indicates that all securities offered hereby have
been sold or which deregisters all securities then remaining unsold shall be
deemed to be incorporated by reference in this registration statement and to be
a part hereof from the date of filing of such documents, except that the
information included in any document in response to paragraphs (i), (k) or (l)
of Item 402 of Regulation S-K is not incorporated by reference in this
registration statement.

         Any statement contained in a document incorporated or deemed to be
incorporated by reference in this registration statement shall be deemed to be
modified or superseded for purposes of this registration statement to the extent
that a statement contained in this registration statement or in any subsequently
filed document which also is or is deemed to be incorporated by reference in
this registration statement modifies or supersedes such statement. Any statement
so modified or 


                                      II-1

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Certificate of Incorporation of the Company provides that, to the
fullest extent that the law of the State of Delaware, as the same exists or may
hereafter be amended, permits elimination of the personal liability of
directors, no director of the Company shall be personally liable to the Company
or to its stockholders for monetary damages for breach of fiduciary duty as a
director. The DGCL permits a corporation's certificate of incorporation to
provide that no director of the corporation shall be personally liable to the
corporation or its stockholders for monetary damages for any breach of his or
her fiduciary duty as a director; provided that such provision shall not
eliminate or limit the liability of a director (i) for any breach of a
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions that are not in good faith or involve intentional misconduct or a
knowing violation of the law, (iii) under Section 174 of the DGCL or (iv) for
any transaction from which the director derived an improper personal benefit.

         The Certificate of Incorporation of the Company also provides, in
general, that the Company shall indemnify its officers and directors against
reasonable expenses and any liability paid or incurred by such person in
connection with any actual or threatened claim, action, suit or proceeding,
civil, criminal, administrative, investigative or other, whether brought by or
in the right of the Company or otherwise, in which he or she may be involved, as
a party or otherwise, by reason of such person being or having been a director
or officer of the Company or by reason of the fact that such person is or was
serving at the request of the Company as a director, officer, employee,
fiduciary or other representative of another corporation, partnership, joint
venture, trust, employee benefit plan or other entity, except as prohibited by
law. Section 145 of the DGCL provides, in general, that each director and
officer of a corporation may be indemnified against expenses (including
attorneys' fees, judgments, fines and amounts paid in settlement) actually and
reasonably incurred in connection with the defense or settlement of any
threatened, pending or completed legal proceedings in which he or she is
involved by reason of the fact the he or she is or was a director or officer if
he or she acted in good faith and in a manner that he or she reasonably believed
to be in or not opposed to the best interests of the corporation and, with
respect to any criminal action or proceeding, if he or she had no reasonable
cause to believe that his or her conduct was unlawful. If the legal proceeding,
however, is by or in the right of the corporation, the director or officer may
not be indemnified in respect of any claim, issue or matter as to which he or
she shall have been adjudged to be liable for negligence or misconduct in the
performance of his or her duty to the corporation unless a court determines
otherwise.

         In addition, the Certificate of Incorporation of the Company provides
that the Company may purchase and maintain insurance to protect itself and any
director or officer entitled to indemnification pursuant to the Certificate of
Incorporation. Accordingly, the Company carries directors and officers liability
coverage which is subject to certain limitations and exclusions.




                                      II-3
   11
         The Company has entered into an Indemnification and Insurance Agreement
with each of its directors (the "Indemnification and Insurance Agreements").
These agreements provide that the Company must, within 30 days of a request,
indemnify an officer or director for liabilities incurred to the fullest extent
permitted by the DGCL. The Company must, within two days of a request, indemnify
an officer or director for expenses incurred in the defense of a claim or other
proceeding. The obligation of the Company to provide the indemnification does
not apply if, before the date on which the Company must provide the
indemnification, the Company's board of directors, or a representative chosen by
the board of directors, concludes that indemnification would be improper under
the DGCL. It is the position of the Commission that indemnification of directors
and officers for liability under the Securities Act is against public policy and
unenforceable pursuant to Section 14 of the Securities Act.

         The preceding discussion of the registrant's Certificate of
Incorporation, Section 145 of the DGCL, and the Indemnification and Insurance
Agreements is not intended to be exhaustive and is qualified in its entirety by
the Certificate of Incorporation, Section 145 of the DGCL and the
Indemnification and Insurance Agreements.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9.  UNDERTAKINGS.

         (a)   Rule 415 offering.

               The undersigned registrant hereby undertakes:

                     (1) To file, during any period in which offers or sales are
               being made, a post-effective amendment to this registration
               statement:

                              (i) To include any prospectus required by 
                     section 10(a)(3)  of the  Securities Act of 1933 (the 
                     "1933 Act");

                             (ii) To reflect in the prospectus any facts or
                     events arising after the effective date of the registration
                     statement (or the most recent post-effective amendment
                     thereof) which, individually or in the aggregate, represent
                     a fundamental change in the information set forth in the
                     registration statement;

                            (iii) To include any material information with
                     respect to the plan of distribution not previously
                     disclosed in the registration statement or any material
                     change to such information in the registration statement;

               Provided, however, that paragraphs (1)(i) and (1)(ii) do not
               apply if the information required to be included in a
               post-effective amendment by those paragraphs is contained in
               periodic reports filed with or furnished to the Securities and
               Exchange Commission by the registrant pursuant to section 13 or
               section 15(d) of the Securities Exchange Act of 1934 (the "1934
               Act") that are incorporated by reference in the registration
               statement;

                     (2) That, for the purpose of determining any liability
               under the 1933 Act, each such post-effective amendment shall be
               deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof; and

                     (3) To remove from registration by means of a
               post-effective amendment any of the securities being registered
               which remain unsold at the termination of the offering.

         (b) Filings incorporating subsequent Exchange Act documents by
reference.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the registrant's
annual report pursuant to section 13(a) or section 15(d) of the 1934 Act that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (h)   Commission opinion regarding indemnification.

         Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 6 above, or
otherwise, the registrant has been advised that, in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the 1933 Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 1933 Act
and will be governed by the final adjudication of such issue.
