Concern with Oil Cooler / Oil Temps

BrandonT

Just wanted to point out a very common misconception: your oil does not need to reach 212F for the water to evaporate. Does a pot of water make no vapor until it boils? If you pour some water on the sidewalk in the summer does it stay there forever? For that matter a little puddle on your kitchen table evaporates quick enough doesn't it? You also have additional help from the oil itself. In very low quantities water is actually repulsed out of the liquid by the oil molecules. You just need it to get hot enough for the tiny amount of water to vaporize/be pushed out in the time your drive takes. This happens pretty quickly.
