is a highly versatile, shear-stable olefin copolymer (OCP) viscosity modifier polymer designed to optimize the rheological properties of automotive engine oils and industrial lubricants. Manufactured by The Lubrizol Corporation , a Berkshire Hathaway specialty chemical company, this polymer serves as a foundational component for lubricant formulators globally. It provides high thickening efficiency, reliable stay-in-grade performance, and outstanding solubility in both mineral and synthetic base oils.
Available as a solid polymer or as a liquid concentrate (e.g., Lubrizol 7077D Functional Products Performance Review 1. Versatility and Grade Coverage
LUBRIZOL® 7067C belongs to the of solid/block olefin copolymer performance polymers. It acts as a rheology modifier by altering the lubricant's viscosity index (VI)—minimizing the rate at which oil thins at high operating temperatures while ensuring fluent circulation during cold startups.

LUBRIZOL® 7067C provides robust stay-in-grade performance across a wide spectrum of multi-grade lubricants. It is a critical component for formulating the following standard Society of Automotive Engineers (SAE) grades: lubrizol 7067c
Lubrizol 7067C is a component used by formulators and oil marketers to create finished lubricants. It is rarely a standalone product.
Many EP additives break down at temperatures exceeding 120°C (248°F), releasing hydrogen sulfide (rotten egg smell) or forming corrosive sludge. Lubrizol 7067C exhibits robust stability up to approximately 160°C (320°F), making it suitable for continuously running industrial units that operate hot.
Lubrizol 7067C is a high-performance, ashless, extreme pressure (EP) additive package. It is specifically engineered for use in industrial gear oils and grease formulations. The "C" designation in the product name typically indicates a specific iteration or variant optimized for a particular balance of solubility and thermal stability. is a highly versatile, shear-stable olefin copolymer (OCP)

viscosity modifier designed for use in a wide range of global engine oils and industrial lubricants. It is primarily recognized for its ability to maintain "stay-in-grade" performance across diverse SAE viscosity grades.

As temperatures change, the polymer chains respond through structural expansion and contraction:
For lubricant blenders, achieving a homogenous product is straightforward but requires precision.
For maximum performance, it is essential to ensure that the additive is completely and uniformly dispersed throughout the base oil. The concentrate should be stored in a dry, well‑ventilated area away from direct sunlight and extreme temperatures.
