This topic is coming up a lot now on other message boards, and it has me wondering a little bit. I've always told people that the reason you want fresh oil in there is so that the acids in the oil don't attack the metal while the engine is sitting for so long. But if the TBN of the oil is still good when you first store your car, won't that neutralize the acids anyways? Or will the engine need to be run on a daily basis in order for that oil to be neutralizing the acids? Am I making any sense here?
