At 100k I flush all fluids of a vehicle.Some manufacturers suggest it a different intervals,but those intervals are put in place by pencil pushing engineers that have never had grease under their nails.It never hurts to change fluids.

thank you, do you also suggest this to be done every 50-60k miles?

If you do this make sure the correct type lubes are put back along with any additives required!
