Keep in mind this gauge in the Giulia is measuring oil temp, not coolant(water) temp. So the behaviour will be different. If you have a car with both gauges you can see that. Water temp is more easily regulated in most cars, and frankly most modern car water temp gauges lie to you anyway. BMW, for example, has rounded off the displayed water temp to the middle of the gauge for years. It doesn't mean the water/coolant is actually spot on the middle of the temp range all the time.
I love that Alfa chose oil temp instead of water temp. It's a lot more useful in knowing exactly when your car is really warmed up. It's an unusual choice compared to every other car company, and a nice one, IMO.

The oil is exposed to the inside engine temps, then cooled by the water jacket, which has a radiator in the loop. The coolant takes heat from the engine, so it seems normal that the oil would be hotter than the coolant.

Oil temperature is probably the most important thing to know, specifically for those of us who are pushing our cars hard. Free reving (or worse - racing) on an engine that has not fully reached it's oil operating temperature is extremely dangerous. But don't think that the coolant gauge will tell you this information - it won't.
As a general rule of thumb, after the car is warmed up, oil tends to be a few degrees warmer than the coolant (usually 10-15 degrees Fahrenheit)
Optymalna temperatura oleju silnikowego kształtuje się na poziomie 90-130° C. Przy dynamicznej jeździe jego temperatura może jednak dojść nawet do 150° C. I mówimy tu o temperaturze mierzonej w misce olejowej. W samym silniku, zwłaszcza w górnej części tłoka (przy wkładce kompensacyjnej tłoka) jego temperatura potrafi dojść nawet do 260° C.
Tak to jest pisac posty nie majac pojecia o czym sie mowi, termostat sie sie sypie ale czy w samochodzie?
