REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Valero Energy Corporation Benefit Plans Administrative Committee:

We have audited the accompanying statements of net assets available for benefits of the Premcor Retirement Savings Plan (the Plan) as of December 31, 2008 and 2007, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2008 and 2007, and the changes in net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule H, line 4i – schedule of assets (held at end of year) as of December 31, 2008 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

PREMCOR RETIREMENT SAVINGS PLAN

1. Description of the Plan

As used in this report, the term Valero may refer, depending upon the context, to Valero Energy Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole.

Valero Energy Corporation is a publicly held independent refining and marketing company with approximately 22,000 employees. As of December 31, 2008, Valero owned and operated 16 refineries in the United States, Canada, and Aruba with a combined total throughput capacity, including processed crude oil, intermediates, and other feedstocks, of approximately 3.0 million barrels per day. Valero markets refined products through an extensive bulk and rack marketing network and a network of approximately 5,800 retail and wholesale branded outlets in the United States, Canada, and Aruba under various brand names including Valero^®, Diamond Shamrock^®, Shamrock^®, Ultramar^®, and Beacon^®.

Valero’s common stock trades on the New York Stock Exchange under the symbol “VLO.”

The following description of the Premcor Retirement Savings Plan (the Plan) provides only general information. Participants should refer to the plan document for a complete description of the Plan’s provisions.

General

The Plan is a qualified profit-sharing plan covering eligible employees of Valero who were formerly employed by The Premcor Refining Group Inc. (PRG), an indirect wholly owned subsidiary of Valero. PRG was previously owned by Premcor Inc. (Premcor), which was acquired by Valero on September 1, 2005. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).

Valero is the plan sponsor and the Valero Energy Corporation Benefit Plans Administrative Committee (the Administrative Committee) is the administrator of the Plan. Vanguard Fiduciary Trust Company (Vanguard) is the trustee and record keeper under the Plan and has custody of the securities and investments of the Plan through a trust.

Participation

Participation in the Plan is voluntary. All union employees eligible under this Plan, other than union employees at the Delaware City Refinery, may participate in the Plan after completing six months of service. Union employees at the Delaware City Refinery are eligible to participate in the Plan after one month of service. Effective January 1, 2007, certain former Premcor union employees became eligible to participate in the Valero Energy Corporation Thrift Plan (Valero Thrift Plan).

Effective July 1, 2007, Valero sold its refinery in Lima, Ohio to Husky Refining Company (Husky), a wholly owned subsidiary of Husky Energy Inc. As a result of the sale, employees at the Lima Refinery became employees of Husky. Those employees who were participants in the Plan became fully vested in their employer accounts and had various options related to their account balances, including a rollover to a Husky defined contribution plan.

Contributions

Participants can make pre-tax contributions from 1% to 50% of their annual eligible compensation as defined in the Plan, subject to certain limitations under the Internal Revenue Code of 1986, as amended

PREMCOR RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS (Continued)

(the Code). Effective April 1, 2007, participants may also make designated Roth contributions to the Plan, which are included in the participant’s gross income at the time of the contribution. Valero matches 200% of the first 3% of compensation that a participant contributes to the Plan. Employer contributions are made in cash. Participants also can elect to make after-tax contributions up to 5% of their compensation; however, Valero does not match these contributions. Total pre-tax and after-tax contributions cannot exceed 50% of compensation. In addition, any participant can make rollover contributions to the Plan and, effective April 1, 2007, a participant can also make an eligible Roth rollover contribution to the Plan. During the years ended December 31, 2008 and 2007, participants made rollover contributions of $263,415 and $895,955, respectively, which are included in employee contributions in the statements of changes in net assets available for benefits.

In addition to the employer contributions noted above, Valero matches 100% of compensation above 3% up to a maximum of 6% that union participants at the Port Arthur Refinery contribute to the Plan, and prior to July 1, 2007, the date the Lima Refinery was sold, Valero matched 100% of compensation above 3% up to a maximum of 6% that union participants at the Lima Refinery contributed to the Plan.

Federal income taxes on pre-tax contributions are deferred until the time a distribution is made to the participant. The Code establishes an annual limitation on the amount of individual pre-tax salary deferral contributions. The limit was $15,500 for each of the years ended December 31, 2008 and 2007. Participants who were eligible to make pre-tax contributions and who attained age 50 before the end of the year were eligible to make an additional catch-up pre-tax contribution of up to $5,000 for each of the years ended December 31, 2008 and 2007.

Forfeitures

Forfeited non-vested accounts of terminated participants can be used to pay the Plan’s administrative expenses or reduce employer contributions. Employer contributions for the year ended December 31, 2008 were reduced by $65,124 related to forfeited non-vested accounts. For the year ended December 31, 2007, no amounts from forfeited non-vested accounts were used to reduce employer contributions. As of December 31, 2008 and 2007, forfeited non-vested accounts available to reduce future employer contributions were $105,251 and $94,464, respectively.

Participant Accounts

Individual accounts are maintained for each Plan participant. A separate account is maintained for each participant’s pre-tax, after-tax, employer matching, and rollover contributions. In addition, effective April 1, 2007, a separate account is maintained for each participant’s designated Roth contribution account and Roth rollover account. The accounts for each participant are adjusted to reflect all contributions, withdrawals, income, expenses, gains, and losses attributable to these accounts.

Effective January 1, 2007, certain former Premcor union employees became eligible to participate in the Valero Thrift Plan. Effective April 9, 2007, these former Premcor employees had the option to transfer their balances from the Plan into the Valero Thrift Plan, of which the total account balance transferred was $4,578,285.

Vesting

Participants are vested 100% in their employee account at all times. Employer matching contributions vest at the rate of 20% per year with 100% vesting after the fifth year of service, except for Delaware City Refinery employees who are immediately fully vested.

PREMCOR RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS (Continued)

The Plan provides that if an employee incurs a break in service prior to becoming vested in any part of his employer account, the employee’s prior continuous service will not be disregarded for purposes of the Plan until the break in service equals or exceeds five successive years. Upon a participant’s termination of employment for other than death, total and permanent disability, or retirement, the non-vested portion of the participant’s employer account is forfeited. In the event the participant is reemployed prior to incurring a break in service of five successive years, any amounts forfeited under this provision will be reinstated.

Investment Options

Participants direct the investment of 100% of their employee and employer contributions and may transfer existing account balances to any of the funds offered. The Plan currently offers mutual funds and a common/collective trust through Vanguard and the Valero Common Stock Fund, which invests 100% in Valero Energy Corporation common stock, as investment options for participants.

Effective September 4, 2007, participants may not designate more than 20% of their contributions to be invested in the Valero Common Stock Fund. Transfers into the Valero Common Stock Fund will not be permitted to the extent a transfer would result in more than 50% of the aggregate value of the participant’s account being invested in the Valero Common Stock Fund.

Withdrawals and Distributions

A participant may withdraw any after-tax contributions or pre-tax contributions after submitting a request to Vanguard. Effective September 1, 2008, a participant may withdraw up to 100% of his vested matching contribution account. Withdrawals of pre-tax contributions or designated Roth contributions before employment ends are limited to hardship withdrawals, under which certain criteria must be met, or attainment of age 59 ¹/2.

Upon a participant’s death, total and permanent disability, or retirement, the participant or the beneficiary of a deceased participant is entitled to a distribution of the entire value of the participant’s employee account and employer account regardless of whether or not the accounts are fully vested. Upon a participant’s termination for any other reason, the participant is entitled to a distribution of only the value of the participant’s employee account and the vested portion of the participant’s employer account. Distributions resulting from any of these occurrences may be received in a single sum. Alternatively, a participant or beneficiary may elect to receive this distribution in the form of equal monthly installments over a period not to exceed fifteen years. In addition, when the value of a distribution to a participant exceeds $1,000, the distribution to a participant who has terminated employment prior to his death, disability, or normal retirement age may be made only with the participant’s consent.

Terminated participants may elect to have the Plan trustee hold their accounts for distribution to them at a date not later than April 1 of the calendar year after which they attain age 70¹/2. In this event, terminated participants continue to share in the income, expenses, gains, and losses of the Plan until their accounts are distributed.

Effective January 1, 2008, the Plan was amended to allow participants who are called to active duty military service and who are on military leave for a period of 179 days or more to make withdrawals of all or any portion of their account. Effective September 12, 2008, the Plan was amended to provide certain relief to a participant whose principal residence on September 12, 2008 was located in the Hurricane Ike disaster area and who sustained an economic loss by reason of Hurricane Ike.

NOTES TO FINANCIAL STATEMENTS (Continued)

Participant Loans

Participants may borrow, subject to certain limitations, amounts credited to their pre-tax contribution account or designated Roth contribution account. The maximum loan amount a participant may have outstanding is restricted to the lesser of:

	(a)		$50,000, reduced by the excess of (i) the highest outstanding balance of the participant’s loans during a one-year period over (ii) the participant’s then currently outstanding loan balance on the day any new loan is made, or
	(b)		one-half of the current value of the participant’s vested interest in his Plan accounts.

The term of any loan may not exceed five years unless the loan is for the purchase of a participant’s principal residence, in which case the term may be longer than five years. The balance of the participant’s employee account and vested portion of his employer account serve as security for the loan. Loans bear interest at a reasonable rate as established by the Administrative Committee, presently at prime plus 1%. As of December 31, 2008, interest rates on outstanding participant loans ranged from 5.0% to 9.75% and maturity dates ranged from January 2009 to October 2018. Loan repayments of principal and interest are made through payroll deductions or as otherwise determined.

Through December 31, 2007, upon a participant’s termination of employment, the entire loan balance became due and payable immediately and reduced any distribution due to the participant. Beginning January 1, 2008, a participant may continue to make loan repayments following termination of employment pursuant to procedures established by Valero.

Plan Expenses

The Plan pays a portion of its administrative expenses, including trustee fees and administrative fees. Plan administrative expenses not paid by the Plan are paid by Valero. Valero also provides certain other services at no cost to the Plan. Investment expenses relating to individual participant transactions, such as fund withdrawal fees, are deducted from the respective participant’s account.

2. Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared on the accrual basis of accounting in accordance with United States generally accepted accounting principles (GAAP).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the amounts reported in the financial statements and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Valuation of Investments

The Plan’s investments are stated at fair value. Valero common stock is valued at its quoted market price as of December 31. Shares of mutual funds are valued at quoted market prices, which represent the net asset value of shares held by the Plan as of December 31.

As described in Financial Accounting Standards Board (FASB) Staff Position Nos. AAG INV-1 and SOP 94-4-1 (FSP), “Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans,” investment contracts held by a defined contribution plan are required to be

PREMCOR RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS (Continued)

reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. As required by the FSP, investments in common/collective trusts that include benefit-responsive investment contracts are presented at fair value in the statement of net assets available for benefits, with a separate adjustment reflected to convert the investments from fair value to contract value. The statement of changes in net assets available for benefits is prepared on a contract value basis.

As provided in the FSP, Vanguard Retirement Savings Trust, a common/collective trust, which primarily holds investments in fully benefit-responsive insurance contracts, is presented in the statement of net assets available for benefits at the fair value of units held by the Plan as of December 31, with separate disclosure of the adjustment to contract value, which is equal to principal balance plus accrued interest. The fair value of the fully benefit-responsive investment contracts is calculated by the issuer using a discounted cash flow model, which considers (i) recent fee bids as determined by recognized dealers, (ii) discount rate, and (iii) the duration of the underlying portfolio securities.

In September 2006, the FASB issued Statement No. 157, “Fair Value Measurements.” Statement No. 157 defines fair value, establishes a framework for measuring fair value under GAAP, and expands disclosures about fair value measures, but does not require any new fair value measurements. The adoption of Statement No. 157 by the Plan effective January 1, 2008 did not affect its financial position or results of operations but did result in additional required disclosures, which are provided in Note 4.

Participant Loans

Participant loans are carried at their outstanding principal balances.

Income Recognition

Purchases and sales of investments are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date.

Net appreciation (depreciation) in fair value of investments consists of net realized gains and losses on the sale of investments and net unrealized appreciation (depreciation) of investments.

Withdrawals by Participants

Withdrawals by participants are recorded when paid.

Risks and Uncertainties

The Plan’s investments, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility risk. Due to the level of risk associated with certain investments, it is reasonably possible that changes in the values of investments will occur in the near term.

The Plan invests in securities with contractual cash flows, such as asset-backed securities, collateralized mortgage obligations, and commercial mortgage-backed securities, including securities backed by subprime mortgage loans. The value, liquidity, and related income of those securities are sensitive to changes in economic conditions, including real estate value, delinquencies or defaults, or both, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates.

Reclassifications

Certain amounts previously reported in the Plan’s annual report on Form 11-K for the year ended December 31, 2007 have been reclassified to conform to the 2008 presentation.

3. Investments

Investments that represent 5% or more of the Plan’s net assets available for benefits are as follows:

		December 31,
		2008				2007

Vanguard 500 Index Fund Signal Shares			10,065,785				16,382,025

The Plan’s investment in shares of Valero common stock represents 8.7% and 12.8% of total investments at fair value as of December 31, 2008 and 2007, respectively. The closing price for Valero common stock was $21.64 and $70.03 on December 31, 2008 and 2007, respectively. As of June 24, 2009, the closing price for Valero common stock was $16.03.

During the years ended December 31, 2008 and 2007, the Plan’s investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated (depreciated) in value as follows:

		Years Ended December 31,
		2008				2007
Valero Energy Corporation common stock		$	(28,654,123	)		$	15,846,793

Net appreciation (depreciation) in fair value of investments		$	(95,338,827	)		$	17,428,211

For the years ended December 31, 2008 and 2007, dividend income included $366,733 and $308,142, respectively, of dividends paid on Valero common stock.

PREMCOR RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS (Continued)

4. Fair Value Measurements

As discussed in Note 2, effective January 1, 2008, the Plan adopted Statement No. 157, which defines fair value, establishes a consistent framework for measuring fair value, establishes a fair value hierarchy (Level 1, Level 2, or Level 3) based on the quality of inputs used to measure fair value, and expands disclosure requirements for fair value measurements. Pursuant to the provisions of Statement No. 157, fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs are based on quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The Plan uses appropriate valuation techniques based on the available inputs to measure the fair values of its applicable assets and liabilities. When available, the Plan measures fair value using Level 1 inputs because they generally provide the most reliable evidence of fair value.

The table below presents information about the Plan’s assets measured at fair value on a recurring basis and indicates the fair value hierarchy of the inputs utilized to determine the fair values as of December 31, 2008. These assets have previously been measured at fair value in accordance with existing GAAP, and the accounting for these assets was not impacted by the adoption of Statement No. 157.

		Fair Value Measurements Using
		Quoted				Significant
		Prices				Other				Significant
		in Active				Observable				Unobservable				Total as of
		Markets				Inputs				Inputs				December 31,
		(Level 1)				(Level 2)				(Level 3)				2008

Investments at fair value		$	142,975,578			$	47,114,044			$	—			$	190,089,622

The valuation methods used to measure the Plan’s financial instruments at fair value are as follows:

	•		Valero Energy Corporation common stock and mutual funds are measured at fair value using a market approach based on quotations from national securities exchanges and are categorized in Level 1 of the fair value hierarchy.
	•		The common/collective trust, which is the Vanguard Retirement Savings Trust, is stated at fair value as determined by the issuer of the fund and is categorized in Level 2 of the fair value hierarchy. The fair value of the Vanguard Retirement Savings Trust is calculated by the issuer using a discounted cash flow model, which considers (i) recent fee bids as determined by recognized dealers, (ii) discount rate, and (iii) the duration of the underlying portfolio securities.

NOTES TO FINANCIAL STATEMENTS (Continued)

5. Party-in-Interest Transactions

The Plan invests in shares of mutual funds and units of a common/collective trust that are managed by an affiliate of Vanguard Fiduciary Trust Company, the Plan’s trustee. Fees paid by the Plan for investment management services were included as a reduction of the return earned on each fund. In addition, the Plan allows for investment in Valero common stock. Valero, the sponsor of the Plan, provides accounting and administrative services at no cost to the Plan. These transactions are covered by an exemption from the “prohibited transactions” provisions of ERISA and the Code.

6. Plan Termination

Although it has not expressed any intent to do so, Valero has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of any termination of the Plan or complete discontinuance of employer contributions, participants would become 100% vested in their employer accounts. If the Plan were terminated, the Administrative Committee would direct the trustee to distribute the remaining assets, after payment of all Plan expenses, to participants and beneficiaries in proportion to their respective balances.

7. Tax Status

The Internal Revenue Service has determined and informed the Plan sponsor by a letter dated April 6, 2009 that the Plan is designed in accordance with applicable sections of the Code.

8. Reconciliation of Financial Statements to Form 5500

Fully benefit-responsive investment contracts are recorded on the Form 5500 at fair value but are adjusted to contract value for financial statement presentation. Deemed distributions of participant loans are recorded on the Form 5500 upon default by participants; such amounts continue to be reported as participant loans in the financial statements until the participants’ termination and actual distribution from the Plan.

The following is a reconciliation of net assets available for benefits per the financial statements to the Form 5500 Annual Return/Report of Employee Benefit Plan:
