I have just noticed on a cold start the oil light on my IS200 takes maybe a full second to go out, that can be overnight cold or left a couple of hours. At a fuel fill up or short stop it goes out immediately on restart
Now my previous cars have tended to do something similar (my old Nissan 4x4 was just the same but 3-4 seconds easy, and was like that for all the years I had it). However, I am wondering if it is something to be concerned about on a 70k miles Lexus engine ? Is it maybe a dodgy oil pump, typical of thin synthetic oil, just how they are ?
