I know that I had to put in a acid neutralizer in my house because it was slowly eating my copper pipes. I'm sure I would have experienced similar problems if it was in my car.
Why would a car that sat a long time matter though? It's a closed system. I can't see how circulating the same fluid would make a difference on corrosion. It seems like if there was a corrosive mixture in the engine, damage would be happening whether it's being run or not. Just wondering what the science it there
