Lubrizol 7067c Work -
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 rig tests without breaking a sweat.
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. lubrizol 7067c
Lubrizol 7067C consists of long, coiled polymer chains. At low temperatures (cold starts), these chains remain tightly coiled, contributing little to the fluid's internal resistance. As the temperature rises, the polymer chains expand and uncoil. This expansion pushes against the flow of the oil, counteracting the natural thinning effect of the base fluid. For those of us blending lubricants, 7067C is a workhorse
While it thickens well at high temperatures, it is engineered not to negatively impact cold-start performance, which is critical for 0W and 5W engine oil grades. Usage and Applications And most importantly, it passes the rig tests
Blending is generally recommended at temperatures between 120°C and 130°C (248°F - 266°F) to ensure complete solubilization.
: The polymer dissolves well in both mineral and synthetic base oils, making it a flexible choice for global lubricant manufacturers.
