Using Transfer Case?

[Roadking]

I don't use the transfer case much. Is it advantageous to run with it engaged once in a while? I don't think I've engaged it for a year? Should I run it at 4-HI on a nice straight road for a few miles once a month, what about 4-L? Run it on a dirt road for a few miles?
Any thoughts.
Do these transfer cases need to be engaged to pump oil through them for the seals sake?

Let me know.

Thanks,
RoadKing

Running in 4 high isnt necessary because you have auto 4x4 that kicks in occasionally. But you should run it in 4-low for a few minutes every few months to get that oil moving.
