Revenue from Contract with Customer [Abstract]
Net Sales	Net Sales Our revenues are primarily derived from the manufacture and sale of petroleum additives products. We sell petroleum additives products across the world to customers located in the United States, Europe, Asia Pacific (including China), Latin America, Canada, India, and the Middle East. Our customers primarily consist of global, national, and independent oil companies. Our contracts generally include one performance obligation, which is providing petroleum additives products. The performance obligation is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts. In limited cases, we collect funds in advance of shipping product to our customers and recognizing the related revenue. These prepayments from customers are recorded as a contract liability to our customer until we recognize the revenue. Some of our contracts include variable consideration in the form of rebates or business development funds. We regularly review both rebates and business development funds and make adjustments when necessary, recognizing the full amount of any adjustment in the period identified. The following table provides information on our net sales by geographic area. Information on net sales by segment is in Note 3.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share We had 22,512 shares of nonvested restricted stock at September 30, 2019 and 24,832 shares of nonvested restricted stock at September 30, 2018 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive. The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yields a more dilutive result than the treasury-stock method. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

Leases [Abstract]
Leases	Leases On January 1, 2019, we adopted Accounting Standards Update No. 2016-02, "Leases (Topic 842)" (ASU 2016-02) using the modified retrospective transition method allowing us to apply the new standard at the adoption date and to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this transition method, the prior comparative period continues to be reported under the accounting standards in effect for that period. We elected the package of practical expedients permitted under the transition guidance which, among other things, allowed us to carry forward the historical lease classification of existing leases. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases and also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. Except for the railcar lease class, we made an accounting policy election to adopt the short-term lease exception, which allows us to not recognize on the balance sheet those leases with terms of 12 months or less resulting in short-term lease payments being recognized in the consolidated statements of income on a straight-line basis over the lease term. We also elected a practical expedient to not separate lease and nonlease components in determining the right-of-use assets and lease liabilities for all lease classes. Adoption of the new standard resulted in recognition of both right-of-use assets and lease liabilities of approximately $70 million as of January 1, 2019. As the right-of-use assets and lease liabilities were substantially the same at adoption, we did not record a cumulative effect adjustment to the opening balance of retained earnings. We have both operating and finance leases with remaining terms ranging from less than one year to 52 years . Our leases are for land, real estate, railcars, vehicles, pipelines, plant equipment, and office equipment. We determine if an arrangement includes a lease at the inception of the agreement. The right-of-use asset and lease liability is determined at the lease commencement date and is based on the present value of estimated lease payments. Our lease agreements contain both fixed and variable lease payments. In some cases, variable lease payments are based on a rate or an index. Fixed lease payments, as well as variable lease payments which are based on a rate or index, are included in the determination of the right-of-use asset and lease liability. Variable lease payments that are not based on a rate or index are expensed when incurred. The present value of estimated lease payments is determined utilizing the rate implicit in the lease agreement, if that rate can be determined. If the implicit rate cannot be determined, the present value of estimated lease payments is determined utilizing our incremental borrowing rate. The incremental borrowing rate is determined at the lease commencement date and is developed utilizing a readily available market interest rate curve adjusted for our credit quality. Some of our leases include an option to renew that can extend the lease term. For those leases which are reasonably certain to be renewed, we included the renewal term in the lease term. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease expense were as follows: Third Quarter Ended September 30, Nine Months Ended September 30, (in thousands) 2019 2019 Operating lease cost $ 4,293 $ 12,821 Finance lease cost: Amortization of assets 684 1,953 Interest on lease liabilities 108 300 Short-term lease cost 812 2,776 Variable lease cost 611 1,653 Total lease cost $ 6,508 $ 19,503 Variable lease costs also include leases that do not have a right-of-use asset or lease liability, but are capitalized as part of inventory.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Matters We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below. While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows. Environmental We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party (PRP). While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our consolidated financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $11 million at September 30, 2019 and $12 million at December 31, 2018 . Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets. Our more significant environmental sites include a former plant site in Louisiana (the Louisiana site) and a Houston, Texas plant site (the Texas site). Together, the amounts accrued on a discounted basis related to these sites represented approximately $8 million of the total accrual above at both September 30, 2019 and December 31, 2018 , using discount rates ranging from 3% to 9% for both periods. The aggregate undiscounted amount for these sites was $10 million at September 30, 2019 and $11 million at December 31, 2018 . Of the total accrued for these two sites, the amount related to remediation of groundwater and soil for the Louisiana site was $4 million at both September 30, 2019 and December 31, 2018 . The amount related to remediation of groundwater and soil for the Texas site was $4 million at both September 30, 2019 and December 31, 2018

Accounting Policies [Abstract]
New Accounting Pronouncements Policy	We adopted Accounting Standard Update No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" (ASU 2018-02) on January 1, 2019. ASU 2018-02 allows, but does not require, reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects that resulted from the enactment of U.S. tax legislation commonly known as the Tax Cuts and Jobs Acts (Tax Reform Act) at the end of 2017. We elected not to reclassify those tax effects from accumulated other comprehensive income upon adoption of ASU 2018-02. We typically remove the tax impact from accumulated other comprehensive income when the underlying circumstance which gave rise to the tax impact no longer exists.
Long-Term Debt	We record the carrying amount of our long-term debt at historical cost, less deferred financing costs related to the 4.10%
Leases	Except for the railcar lease class, we made an accounting policy election to adopt the short-term lease exception, which allows us to not recognize on the balance sheet those leases with terms of 12 months or less resulting in short-term lease payments being recognized in the consolidated statements of income on a straight-line basis over the lease term. We also elected a practical expedient to not separate lease and nonlease components in determining the right-of-use assets and lease liabilities for all lease classes. Adoption of the new standard resulted in recognition of both right-of-use assets and lease liabilities of approximately $70 million as of January 1, 2019. As the right-of-use assets and lease liabilities were substantially the same at adoption, we did not record a cumulative effect adjustment to the opening balance of retained earnings. We have both operating and finance leases with remaining terms ranging from less than one year to 52 years . Our leases are for land, real estate, railcars, vehicles, pipelines, plant equipment, and office equipment. We determine if an arrangement includes a lease at the inception of the agreement. The right-of-use asset and lease liability is determined at the lease commencement date and is based on the present value of estimated lease payments. Our lease agreements contain both fixed and variable lease payments. In some cases, variable lease payments are based on a rate or an index.
