1997 blazer 4dr 4x4

my oil pressure feathers between 45 - 75 and it used to stay solid at around 75... should i be concerned about this?

Completely normal I would say

alright thanks
again there is no weird sounds/it accelerates fine/no knocking just wanted to be sure

It should not be feathering or moving around.
If it is a electric oil pressure gauge.
Time to put a manual test oil pressure gauge on it and find the real pressure.
If good steady pressure on a manual test gauge check the oil pressure sending unit.

it should not flicker around on its own. It will however, move in relation to engine speed (when you press the gas pedal).

20 - 80 is normal on a 1997.
