I'm sure modern day
oil can handle these temperatures. My Audi
oil temp gauge shows 250 F (121 C) when it is right in the middle of the gauge temperature range. My
oil temps are about 85 C when it is 70 F. If you add 30 F (17 C) to the ambient temp, my 85 C temp could easily reach 100 C. Better if some others in hot climates chime in, but I would not do anything. It responds to different operating conditions as expected.
