Thanks for your replies.
I measured it when the car is cold and the engine is not running. I am aware that it should be measured with the engine run and when hot at 80C to get the accurate level. But just to confirm whether it is overfilled. Now I am afraid of warming up the car that the fluid will expend too much to damage oil seals.
Correct me if I am wrong. In my above case the level should be shown just above 25C marks. Right. It is now showing all the way up to lower 80C.
I told them to use MB fluid only the boss assured me that he had to use it.
Thanks again.
