What is everyone's idle oil pressure? Looking at mine today @ 220 water temp at idle and it was 25 PSI which seems low. It quickly climbs to ~40 @ 1500-2000 RPMs so I don't think it's a big deal. Just curious.

From the manual:

Oil Pressure (Minimum - Hot)

At 1,000 RPM
6 psig
41 kPa

At 2,000 RPM
18 psig
124 kPa

At 4,000 RPM
24 psig
165 kPa

6 PSI @ 100o RPM?!? That doesn't seem right but I just double checked my Helms and you are right. Wow.

Would still like to hear what some other peoples' are though.

I didn't want to list mine because I have a ported oil pump but it runs 45psi min. hot at idle up to 80psi at speed. :)

28-32 psi at operating temp.

Sounds just like mine for those temps. What are your oil temps looking like when you've got coolant temps of 220?

HTH, and have a good one,

Oil temps are pretty consistently 10-15 degrees higher than my water temps.

:chevy Your oil pressure almost matches mine and I use 10W30 Mobil 1.

Mine has been this way since new and remains +/- 2 psi.

Sounds normal to me. I have a ported oil pump and run around 25 psi with oil temp about 220.

I have heard that the earlier gages are more accurate where the newer gages are more of a "dummy gage". Not sure if this is true or not though.

That is right where I am after I got rid of the Delco UPF 44 filter.

OK, sounds like we'reall on par. Thanks guys.

My 1999 reflects 29 at idle - hot

Mine runs 28 at idle when I use a Mobile 1 filter. When I used a Napa filter the car was running about 35 at idle. Go figure!
