Oil Temperature

For more than 4 months the oil temperature raises more then normal when I go over 74 mph

Hello,

I have a Alfa Romeo 159 from 2008 with 1.8 GM petrol engine(F18D4 version). For more than 4 months the oil temperature raises more then normal when I go over 74 mph and gets to 130 (266 Fahrenheit ) and keeps getting to 140 (284 Fahrenheit ) if I keep accelerating. When I drive the car under 74 mph the oil temperature is normal.

The normal operating temperature(described by the producer) is 110 C degrees (230 Fahrenheit ) and in the past if I drove the car with 111 mph loaded with people and luggage the oil never reached more then 248 Fahrenheit .

The water temperature remains at 90 C degrees(194 degrees Fahrenheit ) like the producer says, the oil and filters are changed according to the producer specifications.

I went to a mechanic and he said to change the oil temperature sensor but he didn't even checked it.

What should I do?

Kind regards from Europe :)

I would replace the oil temp sensor or sure, cause that's easy and may fix it. If not, engine would be getting the oil too hot and that is an Italian engine known for early wear and overheating. In that case, I'd put on a large oil cooler or just get rid of the car

Thanks for the advice! :)
