mate ,don't feel like that,we are here to learn from each other's experiences and knowlege. ok,I'll try and explane simply; If the oil operates at the same temp. as the coolant then the oil would boil long before the coolant,in this case heat are conducted away from the combution chambers etc.... The oil do basicaly 3 jobs,1) To lubricate moving parts.(friction = heat) 2) To cool moving parts by lubricating. 3) To help trap Nasty/Harmful particulars .( that's why use engine oil are black) .
