Water / oil " normal " temperatures, your input needed ! Options

[Culpable04]

I have a 3rd gen 3sgte with berk tech downpipe, 3" exhaust system, running ~ 15 psi at the moment.

since day one I have had my eyes glued to my oil temperature / pressure gauges.

it has been always ~ 210 degrees F ( ~ 99C ) once the car is warmed up

lately I've seen my olil temperature get up to ~ 220-230F ( 104-110 C ) while cruising at ~ 2500 rpms

I'm using Mobil 1, I'm trying to understand why I'm getting hotter readings than before at the same crusing rpms with no changes on my setup.

also what's the " safe " range for the oil temperature to be ?

I know the 3s has an oil cooler that uses coolant to cool the oil down, so I checked my coolant level and is fine, I'm not leaking / losing any coolant.

any input on this ?

I've got no input as to the temps but the Oil Pressure at startup on mine is a solid 60PSI, drops to 20-40PSI when warm [depending on our wild temp changes here in Houston] and stays pretty much between 30-40PSI at anything other than idle.
Hope this helps in another way.

I can say this tho - As a Lubrication Engineer those numbers all seem high. I design Lube Systems for Cat engines as well as many other manufacturers you guys wouldn't have heard of most likely [Most of them Turbocharged] and I don't see any numbers that high in my tech spec sheets. Optimum temps for these engines are between 90*F and 140*F. Most of these engines are either Deisel or they use the process gas [Natural gas] as a fuel so temps WOULD be lower. This may or may not have any bearing on a Turbocharged 4cyl gasoline engine tho so take all of this with a huge grain of salt.
