Company overview

QUAKER STATE CORP

Quaker State Corp, operating as CIK 81381, maintains a heritage within the lubricants and specialty fluids sector, focusing on premium engine oils, greases, and maintenance additives aimed at independent repair shops, automotive service chains, and consumers who prize long-term protection and reliability for their vehicles; while its publicly listed peers are typically clustered in SIC 2911 (Petroleum Refining) or 2992 (Lubricating Oils), Quaker State emphasizes innovation in synthetic blends and complementary maintenance fluids that help reduce wear across light and heavy-duty fleets. The company reports against evolving environmental and safety standards governing volatile organic compounds, waste disposal, and stormwater runoff, so regulatory shifts, supply-chain volatility for base stocks, and fluctuating crude-derived feedstock costs emerge as principal material risks, alongside litigation exposure from product failure claims. Despite no recent filing data being available, investors should monitor upcoming disclosures for updates on profitability and compliance efforts, and they can view live SEC filings on Earnings Feed.
