: It has a Permanent Shear Stability Index (PSSI) of approximately 25% . This rating indicates its ability to resist mechanical degradation (thinning) when subjected to high-stress environments within an engine, such as the movement of pistons and gears.
), preserving room in the formulation for critical engine oil performance packages.
Whether you are formulating a high‑performance engine oil, a cold‑weather hydraulic fluid, or a biodegradable grease, Lubrizol 7067C provides a proven, reliable solution to meet your performance targets. lubrizol 7067c
For enclosed gear drives operating at high temperatures, the shear stability of Lubrizol 7067C prevents the oil from downgrading to a lower viscosity grade over time, protecting gear teeth from metal-to-metal contact.
Typical use levels of Lubrizol 7067C in a formulated oil can vary significantly depending on the application. A patent example cites using 10% by weight of Lubrizol 7067C as a viscosity index improver in a gasoline engine oil. For general viscosity modification, levels of less than 10% are common, often in the range of 0.5% to 2%. : It has a Permanent Shear Stability Index
Enhances fuel economy by maintaining low HTHS (High-Temperature High-Shear) viscosity limits while protecting modern turbochargers. 10W-40, 15W-40, 20W-50
Lubrizol 7067C is a component used by formulators and oil marketers to create finished lubricants. It is rarely a standalone product. Whether you are formulating a high‑performance engine oil,
The target mineral or synthetic base oil is transferred to a blending vessel equipped with high-shear agitating impellers and preheated to 120°C to 130°C .
Available as a solid polymer or as a liquid concentrate (e.g., Lubrizol 7077D Functional Products Performance Review 1. Versatility and Grade Coverage
39023000 (Propylene copolymers in primary forms) Physical Form: Solid nondispersant polymer matrix
While primarily industrial, some formulators use lower treat rates of 7067C to meet API GL-4 or GL-5 specifications for spiral bevel and hypoid axles. However, formulators must verify copper corrosion compatibility, as high treat rates can be aggressive to yellow metals (bronze, brass synchronizers).
