Hi

I have 2016 lexus is200t, I live in very hot county (46 C)

I want to know what is the normal range of engine oil temperature?

when I speed it reaches 101 , 103 C.

is that normal?

I have no overheating issue, but I’m wondering if oil cooler need to be changed.

 

if you're using full synthetic oil you should be good well up to 120c (as a lower threshold/peace of mind)... based on your current readings your car is doing a great job at cooling the oil with the factory setup

 

103 is pretty good. That's only about 217 degrees Fahrenheit. When I had my Mk7 GTI, it would get up to about 230 if I drove it spiritedly.
