What lube for that tube?

So I have another thread going, tbl with a sticky pivot tube. I am curious what lube most of you use for the grease fittings on the tilt tube and the pivot tube of your outboard engines. I'm tempted to use the bearing grease that I use on my trailer's wheel hubs. However, I recently changed the front hubs on my dual axial trailer which calls for 'Lucas' red bearing grease where the older rear hubs still get the 'green' marine wheel bearing grease. Should I be using something other than wheel bearing grease in the pivot tube or if not whats the difference between the red and green grease? Thanks guys in advance for any comments.
