I have not greased bar since the bar that came with the first saw ever owned. Some manufacturers don't even include a grease hole. I've not had any problems with tips wearing out prematurely.
Really an ole New Englander like you!!!!!!!!!!! Well maybe it doesn't make a difference, maybe the tip gets enough lube from bar oil, maybe not greasing the bar tip would leave out all the aggravation of trying to get that blanking bar tip greaser to work in the first place.
