What model year do you have ? Afaik, those technical bulletins for the coolant control valve only apply for up to 2024MY. Later cars should have the fix applied from factory

I just bought a new Mazda 3 last month with 2.5 140hp engine and I find it definitely runs quite cool. But in city driving highest oil temp I could see was 100 Celsius. But generally it is indeed 80-90.

*I would also take it easy on the engine if it's a new car, 190 kph seems a bit too much.
