low oil pressure
I need help here, I have a 97 Cherokee sport, it has 300,000+ and I recently noticed my oil gauge dropping. It's usually at idle. It drops to about 10 and fluctuates up from there. While accelerating its steady climbing to about 47 and usually stays around 40 at steady rpms. Any ideas on what this issue is?

Could easily be worn bearings with a 300k motor.
It certainly is not impossible that the sending unit is a little off as well. Could verify with a mechanical oil pressure gauge or just install a new sending unit.
If you find out you have 10 psi at idle, I wouldn't be overly concerned.....I've seen 4.0 engines go a long while with that kind of pressure.

What brand of oil filter are you using currently?

Well, then check it with a mechanical gauge and you'll know if it's the sender or actually low pressure.

The only reason I ask is because mine does the same thing. I have 389,XXX miles on my 1990 and it leaks from the rear main. When mine starts to flux, it just means I need to add more oil. Just a thought before you go and spend time and money on a new sending unit.

See Post #10 and put your suspicions to rest. Everything else is pure speculation and guessing.
