i would do the changes less than 5k unless you do alot of highway driving and almost no short trips

I usually use a 3387a Fram filter. These filters are nuts. With it...cold I usually get 60-70 no matter the conditions. Warm at idle, it is around 30, and the needle flutters. At speed, anywhere between 45-70.

Last time I used a "High Mileage" fram filter. With this filter it was 60-70 all the time. Why? It just came to mind that maybe it is like boost. I'm just guessing here, but if you were to put in a less restrictive oil filter, would you get less pressure since it is flowing freer?

Fram oil filters are junk; have you ever cut a Fram Filter open and see how they are built? The only filter I recommend is the OEM AC oil filter, Hastings, NAPA Gold, Mobil 1 or Amsoil (Made by Hastings for Amsoil).

The only time you will see less pressure with a specific brand of oil filter is due to a bad designed filter internal bypass. Fram uses a bypass made from cardboard when others use Viton. A good oil filter also has an internal spring to prevent the element from separating from the base during a pressure spike or due to a defective bypass.

Assuming the last "notch" before 120 is 80, im at 80 when driving and 40 when idle. A little higher than 80 when i first start and its very cold. 92 se

I think i only use fram filters. Are they the ones they sell at walmart with the grip on the bottom so you dont need that tool to take them off?

many edits on this one

mine stays right around 40 most of the time. Sometimes a little higher and when the idle drops, a little lower. but normally right around there.

My car runs 52 psi cold and 46 warm. The OEM oil pump is rated to a maximum of 60 psi @1850 rpm. If you are seeing readings higher than 60 psi, you either have a bad gauge or sender. The oil pump relief valve will bypass to maintain the maximum oil pump design pressure of 60 psi.

The oil volume/pressure kit I installed has bumped my oil pressure from 60 to 80 psi. :P

I can't tell on "my" '93.....it'* pegged out right now. <sheepish grin>....but it is an interesting discussion regarding the oil filters. We use Mobile 1 in both '93 and '00. But I have no clue what oil filter....once the boy puts on a new sending unit, I'll have him monitor the pressure. In my '00 it rarely moves...can't read the darned lines...not sure what the heck it'* at, but it'* always pretty much constant. Slight movement during acceleration, but only one line at the most.

Our '00 SSEi w/160k on it runs ~45psi at idle and ~65psi at 77mph on the freeway. (a little over 2k IIRC) Somewhere in there should be about normal. Anything over 25psi should be plenty for just cruising.

You bet. I had the same experience. Change it and you should smile.

3K is when I change mine, regardless of driving conditions.

That is very high, you might want to look into possible issues.

bifocals

Agreed.
