I juust added an oil cooler when I remoted my oil filter. I can monitor temp and pressure now. I run 196 if I set the electric fans for 200 water temp. I prefer to run 180-190 water temp. This drops oil temp down to 175-180. Any thoughts? I've done an ARx clean out and run 3oz maintenance dose.

Since you have an oil cooler now, it would be best to keep the water temp at 195 degrees, if you have a stock computer on your car it may think that at 180 degrees the car is running too cool and it will add more fuel which can lead to your spark plugs getting fouled and your engine will not run as efficient.
You want your engine to run as hot as it can without overheating.
Awhile back I put on a 180 degree thermostat, I am now running a 195 thermostat and the engine is running better. My feeling is that the hotter coolant temps are helping to burn off any junk or condensation.
Running an engine cooler is for the guys who take there cars to the track. What brand of an oil cooler did you get, is it the tube and fin type or is it the stacked plate design.
I have a 180 tstat in it but the controllers for the fans dictate the water temp. I have a program where I can change any parameter in the ECM. I have it going into closed loop at 160 right now. The spark and fuel tables are setup for power not economy. I have to start out in 2nd when it's wet out. Just wondering about the oil temp since it runs cooler now.
The cooler is an Earl's unit sized for the application I use the truck for. It's a stacked plate and plumbed with -10 stainless steel braided line. We have a place that knows all about hoses and fittings here. They do a lot of specialty work here for the motor city.
You oil temps are fine, imo. If you wanted to run them with the coolant more, try finding one of the big sandwich oil:water coolers that show up occasionally on ebay. This, in conjunction with your Earl's should unload bother systems rather well. Your oil will more conform to the coolant temp ...and your fans will cycle less.
Again, I see no issue with your reported oil temps.
You got the good oil cooler, if you want to know the oil temp you may need to get an oil temp gauge put on or you can get an infrared gun and aim it at the middle of the oil pan on either the drivers side or passenger side, I would aim the gun on whatever side is not near an exhaust pipe.
On my small block chevy the drivers side exhaust pipe is fairly close to the oil pan and I get a reading of 216 degrees but on the passenger side where the exhaust pipe is further away I get a reading of about 195 degrees.
If I had too buy an oil cooler it would either be a B&M unit or an Earl's unit.
The trans cooler is a tube and fin with an electric fan but I hardly see 170 on it. I have an oil temp guage that is a touch screen MSD unit. It even has a trigger wire for an alarm if I want. I have the same guage on the trans temp.
I'm leaving things as they are for the moment but may change to larger fans later if the summer puts to much load on things. This is the first summer it will see and I just want to keep things cool. It sure is nice to not have the parasitic loss of the stock fan.
I just converted my 2.5 SE jeep to electric. I have a sandwich laminar cooler, so my oil temps track my coolant temps pretty close. You can see the thermostat locked down until the oil reaches saturation (about 10 minutes). I set my temps a tad higher than they normally sat for the fan set points. I didn't want the fan running while doing 65mph. It wasn't much. Less than the mechanical fan would allow idling in traffic.
I don't know what it will yield in mpg improvement, but it's quieter now

Yes it is a lot quieter now. I've heard arguements both ways on mileage. You lose the fan drag but there's more load. I don't see much electrical load as there's only a couple of tenths of a volt drop when they're on.
