I want to preface this with my Ram is not a daily driver. It was purchased as a third vehicle primarily for hauling and as an extra vehicle should one of the DD's go down, as is the case now.

My 98 1500 5.2 has run great since I bought it last year. I've put roughly 10,000 miles on it as I've had trouble with the my DD last year. I ran this for a week or so in November with fresh oil and then put her away. She was not driven for about 5 weeks. I started driving her one week ago and noticed the oil pressure is not normal for how it has been in the past. And yes, it does have correct 5w30 oil as per specs.

Normally, after start, oil pressure goes up just above the midline for about 60 seconds and then back below midline for idle, and of course back above for driving/cruising speed. Right now it is staying up above midline almost to the far line. It stays this way for about 20 miles or so before it begins to act normal. The first few days I didn't pay much attention as I figured it was due to it sitting for a while. Here we are a week later, roughly 300 miles and it is still doing the same thing.

I know the pressure isn't maxed out and there is pressure which is good, but it isn't acting normal for how this truck has run since I got it. I wanted to ease my conscience by finding it this was fine or know that there is something wrong so I can get it fixed. Other than this it has run fine with no issues.

Edit: Clarify needle position. Needle sits above 40 but within U shape around 40. Used to idle below 40 two needle widths. Now sits 3 needle widths above 40 at idle but does not go up with acceleration as it would normally until it is well past reaching engine operation temp.

If your truly in doubt t in a manual gadge with the eletric one. But more then likely its the sensor. Mines a DD and it floats arround quite a bit.

+1 most likely a sensor starting to go south on you. I had an old Ford once (notice I said once :D) that literally ate a sensor every winter. The quick way would be to T in a pressure gauge and get a true reading.
