370z running higher oil temperature after oil change

16SportZ

So I had my oil changed by a Nissan dealership that I normally go to each time. I had them put in my usual oil (Castrol Full Synthetic 5W-30), and I also had them install the Greddy Magnetic Oil Drain Plug. After the oil change I could immediately tell something was off about the car. My oil temps are averaging 10 degrees hotter than they were before the oil change. I usually cruise at 185 or so and now it stays at 195-200 when I am not even getting on it. It even stays at these higher temperatures in 60F or 80F outside temperatures. When I get on the car it comes back down to 200 and never lower when it used to drop to 185.. It is a 2016 370z Sport Tech by the way. There is only one time this has happened previously and that was when I first bought the car and took it to the dealership and they put the wrong oil in (0W-20) from their bulk they use for other cars. I had them correct it but I didn't find out they did this until 3k miles later. Every time I go in for an oil change I bring my own oil and filter ever since. Any ideas? I scheduled another oil change and I am going to have them put back in the OEM drain plug because I think that the magnetic piece on the Greddy plug might be heating up and causing the surrounding oil to read at a higher temperature. Just a thought. Any help would be appreciated!

I have a dashcam and I watch them live every time I bring it in. You can watch the oil change I'm referring to here:
