Lubrizol 7067c
When handling concentrated additives like Lubrizol 7067C, standard industrial safety protocols apply.
It is important to distinguish between the additive itself and fluids containing the additive. Many lubricant blenders will advertise that their oil is "Formulated with Lubrizol 7067C." Here is how it stacks up:
| Feature | Lubrizol 7067C | Standard OCP Modifiers | High-Molecular Weight PAO |
| :--- | :--- | :--- | :--- |
| Shear Stability (PSSI) | Excellent (Low) | Poor (High) | Good |
| Low Temp Viscosity | Excellent | Poor | Excellent |
| Cost | Medium/High | Low | Very High |
| Thickening Efficiency | Medium | High | Medium |
| Best Use Case | ATF, Hydraulics | Motor Oils | Compressors, Low Temp | lubrizol 7067c
Note on OEM Fluids: Some manufacturers sell final fluids (e.g., "XYZ Hydraulic Oil") that list Lubrizol 7067C as a component. Buying the raw additive is only practical for commercial lubricant blenders. End-users should look for "Contains PMA VI Improver" on the technical data sheet.
For those of us blending lubricants, 7067C is a workhorse. It offers excellent treat rates (usually between 5.0% and 7.5% depending on the base oil viscosity). It is forgiving with Group I, II, and III base stocks. And most importantly, it passes the ASTM D6121 (L-37) and D5704 (L-60-1) rig tests without breaking a sweat. Buying the raw additive is only practical for
Unlike some high-molecular-weight polymers that trap air (leading to foaming, cavitation, and slow hydraulic response), Lubrizol 7067C, when formulated correctly, maintains good air release properties. This is vital for hydraulic systems operating at high cycles per minute.
Lubrizol 7067C is designed to help finished lubricants meet rigorous industry specifications, including: It offers excellent treat rates (usually between 5
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.
Manufactured by The Lubrizol Corporation—a Berkshire Hathaway company and a global leader in fluid chemistry—this additive is designed to protect metal surfaces under the most severe boundary lubrication conditions. Unlike traditional sulfur-phosphorus additives that may leave metallic ash residues, the "ashless" nature of 7067C minimizes deposit formation on hot metal surfaces, extending equipment life and oil drain intervals.
