Boat trailer greasing

[Sinn]

What brand grease does everyone run on the trailers? I bought a tube from mikes marine last year and hadnt put any yet. Everytime i pull up to the landing i feel my hubs and they are still cool. Im thinking of adding new grease to be safe . Was wondering if there is a grease just as good for a cheaper price cuz i paid near $30 a tube for that one from mikes marine. And how often does everyone else add new grease
