Have lately bookmarked a couple of threads elsewhere on this subject; related:

After running the new oil pressure gauge for a few days now, readings have been:

idle-750 rpm - 19psi
1000 rpm - 30psi
1500 rpm - 50 psi
2000 rpm - 63 psi

The factory gauge in the dash just sits at about 45 always.

. . about temp, here is what I have seen:

Normal town driving coolant 195F, oil 200F-210F

Highway empty at 65-75 coolant 200, oil 220F-240F

Towing in town, backroads (below 60) coolant 200F, oil 220F or so

Towing on highway (10k 5'er) coolant 205F-210F, oil 240F to 250F on longer uphills

Engine RPM over 2k pushes the oil temp to 220F pretty quick if maintained, oil temp directly moves relating to EGT (more load, oil temp moves more than coolant temp) and then back down very slowly.

Takes about 10 minutes at idle or very low load like rolling into campgrounds to get below 220F once it gets up the 240F range and is usually still over 210F when I am parked and unhooked and ready to shut down, EGT is at 300F-350F by the time I am checked in at the gate, so those shutting down after long hard pulls just b/c the EGT is down are forgetting that everything else is totally heat soaked also and cooking under the hood.

Opening the hood upon arrival and letting it idle while unhooking brings the oil temp down about 5* more than leaving it shut -- not much help.

Cooler ambient temps don't make much difference unless below about 30F then I see the oil temps just take longer to get up to 220F or so, but still get and stay there on the highway easily.
