Nice content. I have a vw gti 2016 at 120000 kM. When i am driving i always keep watching oil temperature which bothered me a lot. Please find some authentic information ,what is the max oil temp we should not worry. My one hit 117 deg c on slow drive with 28 deg ambiant temp. 120 140 speed remains 110 deg c. Thanks
