Actually, that is quite normal. Cruising at speeds of 70-80 mph, my oil temperature centers right between the 190-270 mark (Around 230F). His looks slightly higher due to sustaining higher RPM's. This is a topic I recently brought up in another thread and am curious myself if running at 230F for periods of an hour often times is something for me to consider in long term engine wear. I plan on keeping my car for as long as I can, and I DD it somewhat, so I am trying to determine if a Forester heat exchanger is necessary or if these temps are not significant enough to cause any excess wear running on 0W-20.

Also, here are some good reads on the topic of oil and research on brands:
https://www.minimania.com/Motor_Oils..._Misunderstood (Informative of the basics and misunderstandings of oil. Loads of good information).
https://www.ilma.org/PDF/ILMANews/2017/AAAreport.pdf (Not really related to these topics, but just goes to show that there is no reason to be using conventional oil anymore for all new car applications).
https://dextrous-lubricant.com/amsoil/PDF/g3115.pdf (Probably posted a few times somewhere around this thread or others, but some interesting information on brand comparisons).
