Oooops--wrong board. No, seriously, is there any point in greasing the tip of your roller-nose bars? I usually do it for awhile when I get a new saw because they give you a grease gun and a nice tube of bearing grease. But once it runs out, I usually just blow it off and I've never noticed that my tips give out any sooner. I usually manage to kill them long before then through other abuse. So what's the word on the grease?
