The engine oil temp in my 300C recently was as high as 219 degrees. Is this a normal oil temp? What oil would be good for these temps? Currently using Castrol GTX 5w20. Thanks for any feedback........Dennis.
Engine Oil temp. 219 degrees.

Was this the temp in the sump? Was your coolant temp "normal" during this time?
Nothing wrong with that, particularly if that was peak sump temp and not the average one.
Back in the olden daze, 230F was often considered the temp where you should start thinking about an engine oil cooler. With modern oils, it should be less of a problem.
That's because you started the engine and drove the car. Your oil will get warm every time you do that. Don't worry.
Normal warm oil temp is 210-230F (green zone). From 230-250F is kind of a yellow zone. 250-300F is racetrack (red zone) and this is where synthetics shine.
Remember the oil temp you read is an average temp in that area, oil can get much hotter as it passes any corners or thin passages around the cylinders.

If this was his reading (I'm presuming with a guage on the dash, right?), this would be sump oil temperature, right? If this is the case, I now understand why flashpoint does indeed need to be much higher, so as to withstand the higher heat areas of circulation. Given though the speed at which the lubricant is moving through the engine, how much of a cushion is considered adequate in that point?
That's Purrrfect. Get rid of excess fuel, water, and is running about the same temp as the coolant. Could not ask for more.
Is this a 5.7 or 6.1? My 6.1 has been as high as 245 in the AZ desert, but usually runs about 198-217. The 5w-20 is rec. for the 5.7, 0w-40 for the 6.1. I usually run Pennzoil 5w-40 synthetic with excellent wear results, sometimes Mobil 1 0w-40 if I am lazy and have the oil done at a shop. Amsoil 5w-40 also did very well in this engine. I just find the Pennzoil a little easier to get.
I apologize, I see you have the 5.7. Synthetic oil is not necessary, but in a car that nice, I would run it anyways.
Are you sure that's not your water temp? Do they have an oil temp gauge in the 300C?
Yes, it is an electronic gauge which is available by scrolling through the options. It also tells the tire psi on all 4 tires. It is radio controlled and changes when you rotate the tires. Great display on these cars.
John,
I have the same engine. When I get to operating temp on the highway it's at 222*F all day long (for now...summer here in VA). It takes a good 20 minutes to get there.
You have no issue.
My engine and oil is in my sig....

Ooops...forgot.
For those that think that's his coolant temp, no...it's the oil temp. Many of the LX models (Charger, 300, Magnum) have an EVIC which displays many engine/fuel gauges.

weird, it's flip-flopped for my Hondas (Civic & Odyssey):
engine oil operating temp 176F
coolant operating temp 190F
*numbers provided by OEM Honda service manuals for both Civic & Ody.
Specs verified on my Civic via scangauge (coolant temp) and IR thermometer readings on the oil pan.
