In the world of industrial lubricants and chemical manufacturing, the difference between a standard fluid and a high-performance one often comes down to a single component: the additive package. Among the pantheon of industrial additives, Lubrizol 7067C has carved out a reputation as a gold standard for specific, demanding applications. While not a household name, for engineers, procurement specialists, and formulators in the grease and oil industry, this alphanumeric code signifies reliability, extreme pressure protection, and formulation flexibility.
This article provides an in-depth, technical exploration of Lubrizol 7067C. We will cover its chemical composition, primary applications, performance benefits, handling protocols, and how it compares to alternative additives on the market.
Lubrizol 7067C is more than just a chemical product code; it is a solution to the age-old engineering problem of metal-to-metal contact. For formulators and maintenance engineers dealing with heavy gear sets, high-temperature industrial environments, or critical grease applications, this ashless EP additive delivers a unique balance of load-carrying capacity, thermal stability, and system cleanliness.
While it requires careful handling and precise blending, the return on investment is tangible: longer equipment life, extended oil change intervals, and reduced unplanned downtime. As industrial machinery grows more powerful and compact, the demand for high-performing additives like Lubrizol 7067C will only increase.

Lubrizol 7067C: Elevating Engine Oil Performance and Shear Stability
In the demanding world of automotive lubrication, maintaining the perfect viscosity across a wide temperature range is critical. Lubrizol 7067C is a high-performance olefin copolymer (OCP) viscosity modifier engineered to meet these challenges, offering exceptional shear stability and thickening efficiency for premium motor oils. lubrizol 7067c
This post explores the key benefits, application guidelines, and performance advantages of incorporating Lubrizol 7067C into lubricant formulations. What is Lubrizol 7067C?
Lubrizol 7067C is a solid, pelletized olefin copolymer designed as a viscosity index improver (VII). It is often utilized in high-performance engine oils to ensure the oil remains thick enough to protect engines at high temperatures while staying thin enough for efficient lubrication during cold starts. Key Advantages:
Superior Shear Stability: Provides lasting viscosity protection, meaning the oil doesn't break down quickly under heavy mechanical stress, a key factor in extending engine life.
High Thickening Efficiency: Requires a lower treat rate compared to many traditional polymers to reach the same viscosity targets, making it cost-effective.
Improved Low-Temperature Performance: Helps oils meet stringent cold cranking simulator (CCS) requirements, ensuring rapid lubrication during cold weather.
Easy Handling: Being in a solid pellet form, it is easier to store and manage than liquid concentrates. Solubilization and Formulation Guidelines
To unlock the full potential of Lubrizol 7067C, it must be properly solubilized into the base oil. According to industry guidelines for Lubrizol 7060 Series polymers, which include the 7067C type, follow these steps: Have experience blending with Lubrizol 7067C
Shredding: Before mixing, the solid pellet polymer should be shredded into small particles to increase surface area.
Temperature Control: Solubilize the polymer in oil at temperatures between .
Mixing Time: Complete solubilization usually takes 2-3 hours using conventional high-shear mixing equipment.
Verification: Always filter samples to ensure no undissolved polymer remains, ensuring a high-quality finished lubricant. Performance in Motor Oils
Lubrizol 7067C excels in creating high-performance SAE 15W-40, 20W-50, and 25W-50 oils. Performance Characteristic Shear Stability (PSSI) Excellent PSSI ASTM D-6022 (low percent shear loss) Thickening Efficiency High efficiency (approx. 10.5-11.5 cSt @ 1% polymer) Low-Temp CCS (- )
Good control, typically 2400-4000 cP depending on formulation
By utilizing solid polymers like 7067C, manufacturers gain flexibility in base oil selection—including Group II and Group III base stocks—and can reduce shipping costs associated with pre-blended liquid concentrates. Conclusion The Application: Where the Rubber Meets the Road
Lubrizol 7067C is an ideal choice for formulators looking to create robust, shear-stable motor oils that meet modern, rigorous specs. Its high thickening efficiency and superior shear stability make it a reliable partner for engine longevity and performance.

If you can tell me what specific application (e.g., diesel vs. gasoline engines) or viscosity grade (e.g., 5W-30 vs. 15W-40) you are developing, I can provide more tailored performance comparisons. Advantages of Functional V-255 Polymer:
If you walk into a factory running high-pressure injection molding machines or a wind turbine gearbox requiring specific DIN 51524 Part 3 specs, there is a high probability the fluid inside that system was blended using 7067C.
It acts as the "salt and pepper" for the base oil. A blender takes Group I or Group II mineral oils (the base liquid), adds a specific percentage of 7067C (usually around 0.8% to 1.0% by weight), and the result is a premium hydraulic fluid capable of extending the life of equipment by thousands of hours.
The most common application is in heavy-duty industrial gear drives. Gearboxes in steel mills, cement plants, mining conveyors, and wind turbines operate under slow speed, high torque conditions. Here, lubricant films are easily penetrated, leading to micro-welding of gear teeth (scuffing). Lubrizol 7067C provides a sacrificial chemical layer that shears before the metal does, preventing adhesive wear.
Lubrizol 7067C is a component used by formulators and oil marketers to create finished lubricants. It is rarely a standalone product.
Because it is a PMA-based technology, Lubrizol 7067C exhibits better resistance to thermal breakdown than many hydrocarbon-based polymers. It does not readily form varnish or deposits when exposed to high-temperature hot spots inside a transmission or hydraulic system.
