RE: Oil Temp
Just want to confirm,youare talking oiltemp here right, not water temp?
Check the water temp and compare with the information I posted. Also here is information from the service manual for your reference.
If your water tempature is above 225 on a spike Iagree something is amiss, either the t-stat or the temp sensor. I can see 225with a stock 203 t-stat but 260+ would beextreme. I checked mine after I stopped for gas near the house and I let it set for 5 minutes so temps would build up, 215 is the hottest it got to.
If you find your wather temp out of wack take theinformation above, from the manual,to the dealer and ask them to comparethese numbers with the ones they are referencing.
<edited to highlight information from service manual>
Also I checked EVIC and I believe we're talking the same thing here, I didn't find any other tempature besised outside air tempature."Eng Temp" is the item I'm looking at, if you also looking at that then there is an issue that your dealer should look into.

OPERATION
GAS ENGINE
The engine cooling thermostat is a wax pellet driven, reverse poppet choke type. The thermostat is designed to provide the fastest warm up possible by preventing leakage through it and to guarantee a minimum engine operating temperature of 88 to 93° C (192 to 199° F). The thermostat also will automatically reach wide open so it will not restrict flow to the radiator as temperature of the coolant rises in hot weather to around 104° C (220° F). Above this temperature the coolant temperature is controlled by the radiator, fan, and ambient temperature, not the thermostat.
FULL-LOAD PHASE
The main valve is fully open at a coolant temperature above 102° C (216° F). The bypass plate seals off the bypass passage. The entire quantity of coolant flows through the radiator.

Oil Cooler in Ohio?
Years ago I used a low end oil cooler in an attempt to cool an older '79 Buick Regal Turbo. Back then I was using a 20W-50 oil and it would get very viscous in 32degree winter weather passing thru the cooler.
How does the viscosity hold up in the unit that you were suggesting in cold weather? I know with the 5W-20 synthetics the viscosity should be better. I have an '08 RT w/ RT. I added the Mopar CAI, I have a Diablo enroute, and I am picking up a 180 degree thermostat tomorrow. I have noticed the heat soak on my ride this summer.
What make (gsm??) / model cooler do you recommend? Where do I finfd this cooler?? I have been educating myself on all of the mod suggestions. Ones like this appear to make good sense.
Thanks for the help!!
