Lubricant Additive Package (DI Package)

One of the four global lubricant-additive majors (ExxonMobil + Shell joint venture); supplies the DI/VII additive packages that define engine-oil performance.

Afton Chemical Corporation (Richmond, Virginia; subsidiary of NewMarket Corporation; NYSE: NEU; ~$3B revenue) is a major global petroleum additive company producing fuel additives, lubricant additives, and specialty chemicals. Afton produces corrosion inhibitor products for petroleum fuels. In aviation, Afton has a minor CI market presence — its primary strength is lubricant additive packages and gasoline/diesel additives. Afton also has manufacturing at Ellesmere Port, UK, in the same industrial complex as Innospec, creating geographic clustering of aviation fuel additive production.

Chevron Oronite Company LLC (San Ramon, California; Chevron Corporation subsidiary) is a major petroleum additive producer manufacturing fuel additives, lubricant additives, and specialty chemicals for global markets. Chevron Oronite produces corrosion inhibitor packages for petroleum fuels and lubricants. In aviation, Chevron Oronite has a limited direct presence in jet fuel CI specification-approved products, but its broad corrosion inhibitor chemistry portfolio and global manufacturing footprint (Richmond, CA; Ghent, Belgium; Singapore; Tokyo) position it as a potential alternative source if specification qualification processes were pursued. Chevron Oronite's parent gives it integration with Chevron's aviation fuel supply chain.

Lubrizol Corporation (Wickliffe, Ohio; wholly owned Berkshire Hathaway subsidiary since 2011 acquisition for $9.7B by Warren Buffett) is the world's dominant CPVC compound producer and technology licensor, holding a near-monopoly in the US CPVC pipe compound market (~75-80% US share) through its FlowGuard Gold (residential/commercial hot water plumbing) and BlazeMaster (residential and light commercial fire sprinkler systems) branded compound products. Lubrizol owns the critical post-chlorination technology patents and trade secrets for producing CPVC from PVC resin — any CPVC pipe manufacturer globally either sources Lubrizol compound or operates under a Lubrizol technology license. Lubrizol's CPVC lock-in mechanism is similar to its Carbopol brand (polyacrylic acid polymer used in hand sanitizer and personal care gels): Berkshire Hathaway's Lubrizol subsidiary holds dominant market positions in both residential fire sprinkler pipe polymer AND the gelation agent for hand sanitizers. Lubrizol also makes lubricant additives, fuel additives, and specialty industrial chemicals — a specialty chemicals conglomerate that also controls residential fire safety infrastructure materials.
