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.

You will typically find Lubrizol 7067C in action in three specific applications:

Before purchasing, review this checklist:

If you answered "Yes" to three or more of these questions, Lubrizol 7067C is likely the optimal choice.

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.
