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.
While I couldn't find specific reviews or ratings for Lubrizol 7067C, Carbopol polymers, in general, are widely used and well-regarded in the industry for their performance and versatility. lubrizol 7067c
