For me, on bearings, mechanisms and just general friction relief, good old tractor supply on sale stuff has worked just fine for maybe 4 decades..........
For splines, u-joints, and sliding scraping type friction/movement I use a grease with the highest molybdenum content that I can find. Actually, Honda MC dealers carry some great grease of this kind that I use exclusively...........Works for me.......God bless.........Dennis
