I removed an old fence post from its cement block and pounded in a new one.
The new post is 16 inches deep into the old cement block but still wiggles a
few mm on the top. What is the best way to tighten it up?
Is there something I can inject into the gap between the post and the cement
block for this purpose?
I can't believe you're worrying about *a few millimeters* of wiggle at
the *top* of the post; why?
You could probably drive a few 12d or 16d galvanized finishing nails
into the gap on two adjacent sides, using a nail set to get the heads
flush with the concrete. That'd firm it up for the moment.
The swelling and shrinking of a wood post will probably never let you
get it completely locked in.

I remember a post in woodworking NG about a guy who complained his table saw
could not get his down accuracy to 1/16 of an inch.....he said he was hoping
I'd settle for 1/8 myself.....don't worry about the fence post.
Heck my fence moves a couple of inches....
Simpson make an epoxy injection system that goes with their steel
fasteners. You could try and seal the gaps with epoxy.
You could also make some shims and drive them in the gaps.
Line posts shouldn't be set in concrete for this reason.
Go find a pile of sand...get yourself a five gallon plastic
bucket...fill it up with sand...take it to that fence post and start
spooning that sand into the hole surrounding the post...when you get
enough sand in that gap between the post and the block you will know
it...because the post will stop wiggling! You could also through loose
soil into the gap and tamp it down as you pack it in...another neat
trick is just buy yourself a bag of concrete mix at Home Depot and
pour it into the gap between the post and the block hole...after it
rains you will have concrete holding your post in place!
