A 4 ounce tube of grease lasts me years. 4X that for a 1 lb tub.
I still have a pale green tube of Phil grease that I bought with my first good bike in 1989, still some in the tube, I use auto wheel bearing grease now, I think it's better, and the last few years use green marine (boat) wheel bearing grease, as the extensive website for Aaron's Bike Repair (specializing in IGH service) swears by the stuff, especially in the rain. It's a different chemical base, but I don't know exactly how it works. A camper and trailer supply place in town carried it. First ordered off amazon, said green marine, opened the can, was normal grease, I sent back. As with most good greases, a tub of the stuff was about the same price as a small tube of "bike" grease. But the green stuff does not specify a drop point. For anything high temp, I'd use the 500 F auto grease. EDIT: I sit corrected, the green marine grease also says 500 F and meets an ASTM spec.
