High Oil pressure

[fishnhuntnboy]

What would cause my oil pressure to be high when i first start up my truck of the day. it will stay like this until the truck gets warm and then will go down. but if i turn the truck off and it cools back down, the oil pressure will be right back up high like if i am driving down the interstate. It has never done this before so i am a little lost and need some help. I have a 2001 dodge dakota with a 3.9L V6. I did take it out for a little fun a few days ago in the mud and am now regreting it. I am hoping this is and easy fix or nothing wrong at all.

It may be just the sender or gauge is off a little. I would hook a regular oil pressure gauge to it and compare it to the oil gauge on your dash.

how high is high?

did you recently have the oil changed?

[DUCKAHOLIC]

when oil gets cool it gets thicker and causes higher oil pressure but once it warms up it gets thiner and less oil pressure... i wouldnt worry about it unless its reallly high.. my truck when cold going down the road has 75psi oil pressure but when it warms up 50psi going down the road...

Higher pressure when cold is normal. You could always put a mechanical gauge on it to get an accurate psi reading. If your dash is the same as my 02 dakota, there is L \ / H. The \ and / are to indicate normal operating zones. If you are above the / when cold then maybe hook up a gauge and check actual psi. If it just gets to the / then I wouldn't worry. That's where mine gets to when cold everyday.

Recent oil change? What weight oil?

[fishnhuntnboy]

I had an oil change about a 1000 miles ago and its with 5W30.

Gus my gage is the same as yours. It goes to the / but not over it. When warm it will go to the lower \.

Also I am thinking of getting another oil change because i ran the truck hard and when i checked the oil it was a brownish color. Even tho i just had one 1000 miles ago, i think i should be safe to do another one.

[Gus]

I don't think you have anything to worry about pressure wise. That is exactly how mine behaves.

Ok thanks for all the info. I am prolly going to go get an oil change this week and get everything back in order and new oil
