Based on my experience with high-temp bearings, I would give the bearing a shot or two of grease* much more often than 3000 miles. Maybe once a week for a DD.
YMMV. All my experience is with industrial equipment and not turbos.
* Just how much would depend on type of bearing, size, etc.

In most bearing set-ups that I have dealt with. There is a hole that has a pipe plug in it that has to be removed when greasing the bearing. The hole is 180deg from the zerk fitting. This hole is where the old grease is suppose to come out of. If the old grease is hard. You have to use something to poke a hole in the hard grease to get it to flow out of the hole. An auto-greaser might work. We was trying these when I retired.
