DT466 Normal Oil pressure?

[PorchDog]

Just curious as to what normal oil pressures are for an older DT466?

Mine happens to be a 1996 Mechanical with the "standard from the factory" mechanical oil pressure gauge in the instrument panel. 183000 miles and 8900 hours shown on the instrument panel.

Fresh oil change--
Cold start, ambient temperature 48 degrees F-- 55 Psi at idle.
After fully warmed up -- at idle-- 30 Psi.
Slightly revved up, and at highway speeds-- 53 to 55 Psi.

How does yours compare?

Ours is also a 1996. It seems to hang around 55 or so on the highway, more like around 50 at a high idle. I've been working on flushing the old coolant to change over to ELC so I've been running it at a high idle and watching the guages. I'll be changing the oil soon...curious to see if that affects the oil pressure or not.

I have 2 busses.
, 1999 with 200k plus miles….50 psi cold idle, 40 when it warms up. 50 psi while driving.

My second bus, 2006 with a fresh inframe, less than 100 miles on it right now.
70 psi @cold idle, drops to 50 psi when warm, does about 60 psi while driving. This one has fresh oil, Rotella 15w40, and new filters and oil pump too.

my DTA360 when its Hot (180-190).. idles about 20-25 and runs 50-55 highway.. actually reaches 45-50 at about 1500 RPM..
thats running rotella T4 (plain ole oil) 15W40

Maxxforce DT, 220k, 55 psi idling wam or cold, 70 to 80 psi driving cold, 60 driving when warmed up.
