Toyota Rubber Grease. A little pricey but does last as pin lubricant.Molykote M-77 and AS-880N still have a silicone or PAO base. It’s the solid film lubricants like moly, graphite or fluoroplastics that take over once the oil carrier burns off.
Toyota calls for an esoteric glycol-based lithium thickened grease for their slide pins, so does Subaru. Whatever it is, it’s good stuff. On a friend’s Forester that’s exposed to road salt and other flotsam in the winter, the slide pins still move after a yearly brake inspection.
