Performance Review

Shear Stability (25 SSI): It offers excellent shear stability, ensuring the oil stays within its viscosity grade even under the high-stress conditions found in modern engines.

Versatile SAE Grading: Formulators use it to achieve stay-in-grade performance for a wide range of SAE grades, from lightweight 0W-16 to heavy-duty 20W-50.

Solubility and Blending: It is praised for its excellent solubility in both mineral and synthetic base oils, making it easy to incorporate into diverse lubricant formulations.

Handling Flexibility: It is available as a liquid concentrate for easy handling in manufacturing plants, though solid polymer options exist for those who prefer to solubilize in-house to reduce costs. Application & Treat Rates

Lubrizol 7067C is recommended for preparing multigrade crankcase engine oils. Below are the approximate treating levels for various SAE grades as indicated by technical specifications from IMCD: SAE 5W-30: 0.75 – 1.12 wt % SAE 10W-30: 0.56 – 0.75 wt % SAE 10W-40: 1.0 – 1.37 wt % SAE 15W-40: 0.75 – 0.90 wt % SAE 20W-50: 0.66 – 0.87 wt % Expert Summary

Compared to other viscosity modifiers, Lubrizol 7067C is frequently selected for its reliability in global formulations, where consistent performance across varied operating conditions is critical. While it lacks the dispersancy of some specialized polymers, its high thickening power makes it a cost-effective and efficient choice for standard engine oil performance. lubrizol 7067c

Lubrizol® 7067C is a high-performance 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. IMCD Norway Key Technical Specifications Chemistry: Non-dispersant Olefin Copolymer (OCP). Shear Stability (PSSI):

(ASTM D6278), indicating high resistance to mechanical degradation where 75% of the thickening power is retained after use. Thickening Efficiency: Excellent efficiency, requiring approximately

polymer treat rate to achieve target viscosities in standard base oils (e.g., 100N). Physical Form:

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 vs

The standout feature of Lubrizol 7067C is its broad compatibility. It effectively manages viscosity for SAE grades ranging from thin oils to heavy-duty

lubricants. This makes it an ideal "universal" modifier for manufacturers looking to simplify their additive inventory. IMCD Norway 2. Solubility and Blending The polymer exhibits excellent solubility

in both mineral and synthetic base oils. While it is highly efficient, it requires specific handling during blending: IMCD Norway Temperature: For solid versions, solubilization is recommended between 93°C (200°F) 130°C (266°F) Equipment: When mixing with PAO-4 or I-40A base oils, use of

type stirring devices is recommended to manage the high viscosity increase effectively. 3. Comparative Advantage Compared to competitors like Functional V-255

, Lubrizol 7067C offers slightly higher thickening efficiency (12.4% vs 13.0% for a 1000 cSt target) but may have higher Cold Cranking Simulator (CCS) values at low temperatures (-20°C), which is a critical consideration for winter grade formulations. Functional Products Typical Applications Passenger Car Motor Oils (PCMO): Formulating multigrade engine oils. Heavy-Duty Diesel Oils: Used in conjunction with additive packages like Lubrizol 9331 for commercial vehicles. Hydraulic and Transmission Fluids:

Provides stable viscosity index improvement for tractor and industrial hydraulic systems. Lubrizol 7067C is a cost-effective, high-efficiency solution Heavy-Duty Diesel Engine Oils: It is a primary

for lubricant blenders who prioritize shear stability and "stay-in-grade" reliability. While its low-temperature performance (CCS) requires careful formulation in very thin winter grades, its versatility across SAE 0W through 20W ranges remains industry-leading.

Lubrizol 7067C vs. Competitors

To understand its market position, compare 7067C to common alternatives:

Verdict: 7067C is superior to cheap S-P additives for long-life applications; cleaner than ZDDP for gearboxes with copper components.

3. Industrial Gear Oils

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.

4. Applications

Lubrizol 7067C is a component used by formulators and oil marketers to create finished lubricants. It is rarely a standalone product.

Heavy-Duty Diesel Engine Oils: It is a primary component in API CJ-4, CK-4, and FA-4 category oils where soot control is critical.
Passenger Car Motor Oils (PCMO): Used in formulations requiring high levels of sludge control (e.g., API SN, SP categories).
Natural Gas Engine Oils: Where oxidation stability and deposit control are required.
Industrial Lubricants: Occasionally used in hydraulic fluids or circulating oils where high purity and deposit control are desired.

✅ Strengths (why people like it)

Excellent emulsion stability – Provides fine, stable oil-in-water emulsions, even with hard-to-emulsify base oils (e.g., paraffinic or naphthenic oils).
Low foaming – Performs well in high-shear or recirculating systems (e.g., central coolant systems).
Good hard water tolerance – Maintains performance in moderate to high water hardness without breaking emulsion.
Compatible with additives – Works well with biocides, corrosion inhibitors, and extreme pressure (EP) additives.
Biostable – Helps resist bacterial growth compared to some ester-based emulsifiers, extending sump life.

Versatile Treat Rates

The product offers formulation flexibility:

Low treat (1.5%): Rust and oxidation inhibited (R&O) oils with mild EP protection.
