oil pressure

[Wolfie]

i was just wondering what the optimal readout on the oil pressure gauge should read? ive already stated previously to my lack of knowledge when it comes to cars (getting better thanks to this forum tho!), and was wondering what exactly the oil pressure gauge should be reading. i just got back from taking the charger out for a decent drive and i notice the oil pressure drops low when stopped at a light/ideling , but then rises when the car starts to pick up speed. is this normal, or is this something i should be concerned about? thanks.

Your oil pump is working correctly.
It's normal for the oil pressure to drop along with the revs when stationary.

I didn't notice if you mentioned the model of car or the guage, but there are several rules of thought on this subject. If all is normal, you will have the lowest pressure at idle. Several things will affect pressure though. Cold engine and thick oil will certainly show higher pressure at the guage. Imagine what the guage looks like in 100 degree weather if you have 5w20 oil!
There are several sources for determining which grade of oil to use. Most stock Mopar engines in 60 degree weather can do well with 10w40. I'm not sure if you are aware though that most of the oils today actually lack a very important "ingredient" known as "Zinc Phosphate". I mention this as a warning because in some cases, engines can suffer early failures because of it. There are oil additives that you can pour in to make up for it, or you can use special oil that is specially formulated for old traditional engines.
I hope I didn't scare you off with the boring story on oil. Good luck !
