It’s not important at all. The cassette lockring just has to be tight enough to not come off as it’s not doing anything other than keeping the cassette from sliding off – some cassette lockrings are even make of aluminum. Use a long wrench and put a bit of force behind it and you’ll be fine.

Can you over tighten a cassette?

Only thing I’ll add is that it is possible to over-tighten a lockring and damage the freehub. Specifically the DT 240S freehub for Campy. The shoulder/flange the cassette tightens against is very thin metal and I did managed to crack one by overtightening.

Should you grease cassette lockring?

If the bearings are sealed (so dirt can’t get into the bearing), and there isn’t an interface (two surfaces rubbing together), than lube is probably not needed. Adding lube may actually create a dirt-trap as more dirt sticks rather than just getting in there and falling back out.

How do I know if my cassette is tight enough?

Come on, not finger tight. but at least using a 1′ long wrench and clicking in a few notches till it seems harder to click more than 2 a the time is often enough. trial and error will get you there on how tight you should make it so it’s easy to take off and not loosening in the long run.
