I have a 97, 3.9L, and mine is normally at the 3/4 mark, I don't remember the actual numbers. Only sometimes at idle will it drop a little above the 1/4 mark. It has about 85K miles, and is an automatic.

when the truck is idling it is normal for the oil pressure to go down..to an extent. if it goes down exessively it means ur oil pump isnt picking up any oil. if thats happening there is a problem with your oilpump or most of the time u dont have enough oil

sometimes oil filters can clog up too

I have a 97 DAK with 174K on the motor. I started having the same problem at about 130K. I went to 20w 50 oil and my preasure runs fine. i tried going back to 10w-40 and it went back to low oil pressure. this next oil change, I am going to try 15w-40 and see what that does.

I have a 95 Dakota with 159K and I too have low oil pressure at idle and sometimes the red oil light comes on. I thought it was the oil pump but mechanic said that the oil pump was fine. I use 10W-30 oil but might try a different oil weight.

I have an '02 with 33K miles on it and my oil pressure is lower when idleing than it is when moving. I never thought it could be something wrong, seems almost like commons sense that the pressure would be lower.

The pressure will drop when you idle, especially after the engine has warmed up. If it is too low, it will be either the filter, age of oil(viscocity), oil filter, or the pick-up(it has a little sock on the end on it that extends down into the pan, and sometimes it gets deposits on it)

Sorry one of those "filters" should have been a "pump"!:)

I have never had a problem with oil pressure being low (knock on wood). But seeing that someone said to run a 20-50, you might want to consider a synthetic. They are SUPPOSED to keep oil pressure more consistant. If you life in the wrong climate a 20-50 could do more harm than good, and you will be replacing your oil pump because the oil is too thick. Just a little FYI on synthetics. I use AMSOIL 10-30 and have about 10k on it and it still holds pretty consistant. There is still some fluctuation, but better than before and better than our 5.9 Durango, which has 10-30 MaxLife. Hope that helps.

Matt

I tried synthetic oil 10W-30 and had the same low oil preasure. At idle, right on the low end line. Driving is fine. I live in the south where we do not have the real cold temps. I have tried running 3 qts of 20w-50 and the remaining oil at 10w-30 and that did ok. That is my winter mix I run (Jan - Feb).

I have a 98 3.9 w/ 85k on it, and my oil pressure drops too. I figure its because the motor only takes 4 quarts of oil in the first place.

I have a '99 Dodge Dakota with the 3.9 v6 in it. I noticed on the way home that my oil pressure guage dropped to zero and the check gauges light came on. I pulled it over shut it off, checked the oil {which was fine} waited a few more minutes and then it did it again. Then after a few more minutes i heard the motor start knocking real bad. I shut it off and towed it home. #1 to me it sounds like the oil pump has went out on it.#2 do you think i did any permanant damage to the motor, I did'nt lock it up? #3 is there any current recalls on oil pump on this type of motor?

had a 2000 cc service truck at work once, did the same thing oil pressure went to 0, check engine light came on, checked the, oil and all was good, kept driving the vehicle and it stalled repeatedly took it to get it serviced and was told that #1 the oil pump was bad and #2 they changed the weight of the oil, never had the problem again, Cuda Man: it is hard to tell you might have some damage, because of the knocking, almost like my work truck but instead of knocking it just stalled out, it's good you got it towed though, never had any major problems relating to my incident but who knows, your's might be different, good luck and let us know how it turns out.

My truck looks like it was in a knife fight, and lost! http://www.cardomain.com/ride/1275365

To start out it is perfectly normal to have a pressure drop at idle. this is because the pump is not turning as fast at idle as at a driving speed.

Second, Cuda Man. I would do some homework on your motor before you take it to a shop. Do a complete oil change and filter change. depending on the knock you heard your motor could be fine. valve tap is the first sounds you hear with no oil pressure. once you change your oil, pull your coil wire and crank the motor for about 15 seconds. if your pump is working this should produce some oil pressure. not alot but some. you may not want to rely on your dash gauge, you might want to try a analog gauge from the block to see pressure.
