Simple(?) question:
How much heat can a modern synthetic motoroil take, or are there no given guidelines?
Previous I hade a BMW M3 -96 and the user manual said - "For short times you can let the oil
get up to 130C (266F)." To me that is hot!
But when is the oil "used up" of the heat-treatment? one 130C run, or two 130C runs, or hundred 130C runs?
Does this show in a UOA?
What oiltemps do you usually have during "normal" driving?
I have one car with tempgauge (Corvette C5 -00) and it stops around 92C (198F) (I'm using M1 0w-40).
Are there any data from the oilmanufacturer that can give a hint on this, or is it trail and error?
