My 2007 G35S (over 180K km) still runs like a new car comparing to my 2017 GSF...
I keep changing engine oil every 5000km with good oil. Now engine oil in my old G still looks quite clear even though it already runs over 3500km and the engine is also quieter than my new GSF...
PS: I'm quite picky on car performance. You don't need to do the same like me...
