as long as it stays in the the nomal area ,its ok . just means @ an idle the pressure is lower . is normal for it to go up and down . if your oil pressure gets to low the check gauge, or engine light will come on .

SOURCE: Losing Oil Pressure in Dodge Ram
I have a 1999 dodge ram with a 5.9liter. Come to a stop and bam no pressure. Replaced sending unit twice. First after market, then mopar. Problem is still there. Replaced pump. Problem was still there. So I talked to tons of dodge mechanics, and this is the real problem. Who ever said that these engines are none for sludge is just reall really stupid. BOTTOM LINE ON THAT FACT. Sludge comes from neglect...
Dodges oil pump makes 8-10 Psi at idle. Always mechanically test that no MATTER what. But the sending unit needs 12-14 psi to read it. So what happens is the engine warms up, and the oil thins. Then you come to a stop, and rpms are low, and your not producing enough psi for the sending unit to read it. So your truck is fine. But if the chime is getting to you. Install a high volume pump. I returned the stock one, and got the high volume pump. I will bet if you change your oil every 3,000 miles you will not see sludge at all. If your dodge has high miles replace valve cover gaskets, becauce the high volume pump may cause the gaskets to leak. Whoever said ther none for sludge just has no love for a dodge, or is a moron mechanic that is stuck in his ways. High volume pump is the fix $85.00 plus pan gasket. If you have a 4x4 you can do it yourself. Drop the starter. Remove torque converter cover. With a 13mm socket with a variety of extentions, and removing a dozen bolts. Do it yourselfer will complete it in 4 hours....
