192 plus or minus is a good place to be, and if it's doing that during any activity you partake in, let it alone.
trying to get something to stay at 160 might be the racer's trick for every last hp, but will only lead to build ups of acids, water, and other things in the oil you do not want.
the heat is necessary to burn that stuff off and keep your engine healthy.
if it's not puking, steaming, snapping and cracking, or other overheating symptoms, you are golden.
at one time, i believed in the "keep it at 160" as well, but after almost 60 years of playing with engines, i now like higher temperatures, even on our typical stuff, and i don't get concerned until something gets to around 230ish for a bit.
even 200 or 205 in stop and go traffic doesn't bother me. if your cooling system is good, nothing to worry about.
i am on the higher end of the temperature scale than some are comfortable with, but after all these years, i have had few if any problems doing so.
just my life experience. your mileage will vary.
