Temps under load creeping up.
After my break-in period and first oil change, my '23 never got above about 217F. At a year or so in, pushing it hard would get it to 219F. Oil change before last, it started reaching 221F at about 100mph. I got my oil changed last week, then drove in similar conditions, and the temps peaked at 226F. Air temps were roughly the same, low high 80s to low 90s.
No mods, no tune, 16k miles. All oil changes done at dealership. Radiator looks fine, coolant levels are normal. No CEL or anything to indicate anything wrong, just peak temps slowly creeping.
Any idea if this is normal? I'm leaning towards it just being a hair less efficient at shedding the heat over time, for various reasons, but I wanted to double check.
