 Exhibit 4.2 

VALERO ENERGY CORPORATION 

4.350% Senior Notes due 2028 
 A
single series of Securities is hereby established pursuant to Section 301 of the Indenture dated as of March 10, 2015 (the “Indenture”), between Valero Energy Corporation, a Delaware corporation (the “Company”), and
U.S. Bank National Association, as Trustee (in such capacity, the “Trustee”), as follows (capitalized terms used and not defined herein shall have the meanings assigned to them in the Indenture, and all references herein to a Section shall
refer to the corresponding Section in the Indenture): 
 1. The title of the 4.350% Senior Notes due 2028 shall be “4.350% Notes due
2028” (the “Notes”). 
 2. The initial limit upon the aggregate principal amount of the Notes that may be authenticated and
delivered under the Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 304, 305, 306, 906 or 1207) is $750,000,000, provided, however, that
the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution to such effect. 
 3. The
Notes shall be initially issued as Registered Securities in the form of one or more global securities under the Indenture. The Depository Trust Company is hereby designated as the Depository for these global Securities under the Indenture. 

As long as any Note is in global form, then, notwithstanding clause (11) of Section 301 and the provisions of Section 302, any
such global Note shall represent such of the outstanding Notes as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of
outstanding Notes represented thereby may from time to time be reduced to reflect exchanges or redemptions. Any endorsement of a global Note to reflect the amount, or any increase or decrease in the amount, of outstanding Notes represented thereby
shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified in such Note or in a Company Order to be delivered to the Trustee pursuant to Section 303. Subject to the provisions of
Section 303 and, if applicable Section 304, the Trustee shall deliver and redeliver any Note in permanent global form in the manner and upon instructions given by the Person or Persons specified in such Note or in the applicable Company
Order. With respect to Notes that are represented by a global Note, the Company authorizes the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the
Depository appointed with respect to such global Note. Any global Note may be deposited with the Depository or its nominee, or may remain in the custody of the Trustee pursuant to a FAST Balance Certificate Agreement or similar agreement between the
Trustee and the Depository. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Note in global form shall be in writing but need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel. 
 Members of, or participants in, the Depository (“Agent
Members”) shall have no rights under the Indenture with respect to any global Note held on their behalf by the Depository, or the Trustee as its custodian, or under such global Note and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of such global Note for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a global Note may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through an Agent Member, to take any action that a Holder is entitled to take under the Indenture or the Notes and (ii) nothing herein shall prevent the Company, the Trustee or
any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depository or shall impair, as between the Depository and its Agent Members, the operation of customary practices
governing the exercise of the rights of a beneficial owner of any Note. 
 Notwithstanding Section 305, and except as otherwise
provided pursuant to Section 301, transfers of a global Note shall be limited to transfers of such global Note in whole but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in a global
Note may be transferred in accordance with the rules and procedures of the Depository. In all other respects, Notes shall be transferred to all beneficial owners in exchange for their beneficial interest in a global Security solely as expressly
provided in Section 305. 
 In connection with any transfer of a portion of the beneficial interest in a global Note to beneficial
owners pursuant hereto and Section 305, the Security Registrar shall reflect on its books and records the date and a decrease in the principal amount of the global Note in an amount equal to the principal amount of the beneficial interest in
the global Note to be transferred, and the Company shall execute, and the Trustee upon receipt of a Company Order for the authentication and delivery of Notes shall authenticate and deliver, one or more Notes of like tenor and amount. 

  
 1 







 In connection with the transfer of an entire global Note to beneficial owners pursuant hereto and
Section 305, the global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange
for its beneficial interest in the global Note, an equal aggregate principal amount of Notes of authorized denominations. 
 Neither the
Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Notes by the Depository, or for maintaining, supervising or reviewing any records of the Depository relating
to the Notes. Neither the Company nor the Trustee shall be liable for any delay by the related global Note Holder or the Depository in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in
relying on, instructions from such global Note Holder or the Depository for all purposes (including with respect to the registration and delivery, and the principal amount, of the Notes to be issued). 

Notwithstanding the provisions of Sections 201 and 307, unless otherwise specified as contemplated by Section 301, payment of principal
of, premium (if any) or interest on any global Note shall be made to the Person or Persons specified in such global Note. 
 5. The date on
which the principal of the Notes are payable shall be June 1, 2028. 
 6. The rate at which the Notes shall bear interest shall be
4.350% per annum. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The date from which interest shall accrue for the Notes shall be
June 1, 2018. The Interest Payment Dates on which interest on the Notes shall be payable are June 1 and December 1, commencing December 1, 2018. Interest on the Notes shall be payable to the persons in whose name the Notes are
registered at the close of business on the Regular Record Date for such interest payment, except in the case of default interest, which will be payable as provided in the Indenture. The Regular Record Date for the interest payable on the Notes on
any Interest Payment Date shall be the May 15 and November 15, as the case may be, immediately preceding such Interest Payment Date. No Additional Amounts shall be payable with respect to the Notes. 

7. The place or places where the principal of, premium (if any) on and interest on the Notes shall be payable is at the office or agency of
the Paying Agent and Security Registrar in New York, New York or such other offices or agencies maintained for such purpose as the Company may from time to time and in accordance with the Indenture designate. If appropriate wire transfer
instructions have been received by the Trustee, not later than five Business Days prior to the record date for an applicable Interest Payment Date, then payments in respect of the Notes evidenced by a global Security (including principal, premium,
if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder of such global Note. In all other cases, payment of interest on the Notes may be made at the option of the Company by check
mailed to the address of the person entitled thereto as such address shall appear in the Security Register. 
 8. The Notes will be
redeemable at any time and from time to time prior to March 1, 2028, in whole or in part, at the option of the Company, at a redemption price equal to the greater of (i) 100% of the principal amount of such Notes, and (ii) the sum of the
present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption) calculated as if the maturity date of the Notes was March 1,
2028, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined
below) plus 20 basis points, as calculated by an Independent Investment Banker (as defined below) plus, in each case, accrued and unpaid interest thereon to the date of redemption; provided that the principal amount of a Security outstanding after
redemption in part shall be $2,000 or an integral multiple of $1,000 in excess thereof. 
 On or after March 1, 2028, the Notes will be
redeemable at any time, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of redemption. 

“Adjusted Treasury Rate” means, with respect to any date of redemption, (i) the yield, under the heading
which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the
Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the remaining life, yields for the two 

  
 2 







 
published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual
equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such date of redemption. The
Adjusted Treasury Rate shall be calculated on the third Business Day preceding the date of redemption. 
 “Comparable
Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes (assuming, for this purpose, that the Notes matured on March 1,
2028) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes (assuming, for this purpose,
that the Notes matured on March 1, 2028). 
 “Comparable Treasury Price” means, with respect to any
date of redemption, (i) the average of five Reference Treasury Dealer Quotations for such date of redemption, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker
obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the independent investment banker from time to time. 
 “Reference Treasury Dealers” means (i) Merrill
Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, and Wells Fargo Securities, LLC or their respective successors; provided that, if any of the foregoing shall cease to be a primary
U.S. Government securities dealer (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any date of
redemption, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such date of redemption. 
 Notice
of any redemption will be mailed at least 30 days but not more than 60 days before the date of redemption to each Holder of the Notes to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the date of
redemption, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 9. The Notes shall not be entitled to
the benefit of any sinking fund, any optional repurchase or redemption right in favor of any holder thereof or other mandatory repurchase or redemption provisions. 

10. The Notes shall be in substantially the form of Attachment A hereto (the “Form of Note”). 

11. Each Note that is a global Security shall bear the legend set forth on the face of the Form of Note.

NOTES DUE 2028

 1. Interest. The Company promises to pay interest on the principal
amount of this Security at 4.350% per annum from June 1, 2018 until June 1, 2028 (“Maturity”). The Company will pay interest semiannually on June 1 and December 1 of each year (each an “Interest Payment
Date”) and on the Maturity of the Securities, or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid
or, if no interest has been paid, from June 1, 2018; provided that if there is no existing Default in the payment of, or provisions for, interest, and if this Security is authenticated between a Regular Record Date referred to on the face
hereof (whether or not a Business Day) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be December 1, 2018. The
interest so payable, and punctually paid or provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest as set forth on the face hereof; provided, however, that interest payable at Maturity of this Security will be payable to the Person to whom the principal hereof shall be payable. Any such
interest which is so payable, but is not punctually paid or duly provided for on any Interest Payment Date, shall forthwith cease to be payable to the registered Holder on such Regular Record Date, and may be paid as more fully provided in the
Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or
agency of the Company maintained for that purpose in New York, New York, or at such other offices or agencies maintained for such purpose as the Company may from time to time and in accordance with the Indenture designate, in such coin or currency

mailed to the address of the Person entitled thereto as such address shall appear on the Security Register or, with respect to Securities evidenced by a global Security, if appropriate wire transfer instructions have been received in writing by the
Trustee, not later than five Business Days prior to the record date for an applicable Interest Payment Date, be made by wire transfer of immediately available funds in accordance with such wire transfer instructions; and (ii) payment of
available funds upon surrender of this Security will be made at the office or agency of the Company maintained for that purpose in New York, New York or at such additional offices or agencies maintained for such purpose as the Company may from time

the Securities and the Indenture may be served, U.S. Bank National Association, the Trustee under the Indenture, will act at its offices located at Houston Greenway Plaza, 8 Greenway Plaza, Suite 1100, Houston, TX 77046-0892. 

4. Indenture. The Company issued the Securities under an Indenture dated as of March 10, 2015 (the “Indenture”)
between the Company and the Trustee. The terms of the Securities include those stated in the Indenture (including terms defined therein, which terms when used herein, unless the context requires otherwise, shall have the meanings assigned to such
terms in the Indenture) and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date of execution of the Indenture. The Securities are subject to all such
terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Securities are unsecured general obligations of the Company initially limited to $750,000,000 in aggregate principal amount and will rank on a parity
with all other unsecured and unsubordinated indebtedness of the Company; provided, however, that the authorized aggregate principal amount of the Securities may be increased above such amount by a Board Resolution to such effect. The Indenture
provides for the issuance of other series of debentures, notes and other evidences of indebtedness (including the Securities, the “Debt Securities”) thereunder.

will be redeemable at any time, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of such Securities, plus accrued and unpaid interest to, but not including, the date of redemption. 

“Adjusted Treasury Rate” means, with respect to any date of redemption, (i) the yield, under the heading
which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the
Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the remaining life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be
interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable

Banker as having a maturity comparable to the remaining term of the Notes (assuming, for this purpose, that the Securities matured on March 1, 2028) that would be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes (assuming, for this purpose, that the Securities matured on March 1, 2028). 

“Comparable Treasury Price” means, with respect to any date of redemption, (i) the average of five

8. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be supplemented with the
consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Securities, and any past default under the Indenture with respect to the Securities, and its consequences, may be waived (other than a default in the
payment of the principal of (or premium, if any) or interest on the Securities or in respect of a covenant or provision of the Indenture which under Article 9 thereof cannot be modified or amended without the consent of the Holder of each
outstanding Security) by the Holders of not less than a majority in principal amount of the outstanding Securities in accordance with the terms of the Indenture. Without the consent of any Holder, the Company and the Trustee may supplement the
Indenture or the Securities (i) to cure any ambiguity, omission, defect or inconsistency, in each case which shall not be inconsistent with the provisions of the Indenture and which shall not adversely affect the interest of the Holders of the
Securities in any material respect; (ii) to evidence the assumption by a successor Person of the obligations of the Company under the Indenture and this Security; (iii) to change or eliminate any restrictions on the payment of principal
(or premium, if any) on Registered Securities, to permit Registered Securities to be exchanged for Bearer Securities or to permit the issuance of Securities in uncertificated form, provided any such action shall not adversely affect the interest of
the Holders of the Securities in any material respect; (iv) to add to the covenants of the Company for the benefit of the Holders of the Securities or Holders of other series of Debt Securities, or to surrender any right or power conferred by
the Indenture upon the Company; (v) to add to, delete from or revise the conditions, limitations and restrictions on the authorized amount, terms or purpose of issue, authentication and delivery of the Securities as set forth in the Indenture;
or (vi) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee with respect to the Securities and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or
facilitate the administration of the trusts thereunder by more than one Trustee, pursuant to the requirements of the Indenture. 
 The right
of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such
Holder shall have been the Holder of record of any Securities with respect to which consent is required or sought as of a date fixed in accordance with the terms of the Indenture. 

Subject to certain exceptions and limitations set forth in the Indenture, without the consent of each Holder affected, the Company may not
(i) change the Stated Maturity of the principal of or any installment of interest on any Security, (ii) reduce the principal amount of, or any premium or interest on, any Security, (iii) change any Place of Payment where, or the
currency in which, any Security or any premium or interest thereon is payable, (iv) impair the right to institute suit for the enforcement of any payment with respect to any Security after the Stated Maturity thereof (or, in the case of
redemption, on or after the applicable Redemption Date), (v) reduce the percentage in principal amount of the outstanding Securities whose Holders must consent to a supplement or waiver, or reduce the requirements in Section 1504 of the
Indenture for quorum or voting, or make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of the Indenture or (vi) waive a continuing Default or Event of Default in the payment
of principal of or premium (if any) or interest on the Securities. 
 A supplemental indenture that changes or eliminates any covenant or
other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series. 

9. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) failure to pay principal of or
any premium on any Security when due and payable; (ii) failure to pay any interest on any Security when due and payable, and the continuation of the default for 30 days; (iii) failure to perform any other covenant, or breach of any
warranty, of the Company in the Indenture, continued for 60 days after written notice is given or received as provided in the Indenture; and (iv) certain events of bankruptcy, insolvency or reorganization. If any Event of Default at any time
outstanding occurs and is continuing, either the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Securities may declare the principal amount of all Securities to be due and payable immediately. At any
time after a declaration or 

  
 A-8 







 
occurrence of acceleration with respect to the Securities has been made, but before a judgment or decree based on acceleration has been obtained, the Event of Default giving rise to such
declaration of acceleration shall, under certain circumstances, be deemed to have been waived, and such declaration and its consequences shall be deemed to have been rescinded and annulled. 

Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity reasonably
satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power with
