No, you're missing my point entirely. I agree completely with what you are saying. What I am trying to convey is: I run the oil through the course of the year. As time progresses the pH level drops. As you know when the pH drops below 7.0 you are acidic. If I let it sit over the winter before my next oil change, the acidic nature of the oil will start tend to corrode (admittedly not to the point of burning a hole in the block) metals in contact with it. I change it at the end of the year so that clean, new oil is what sits in the engine over the winter. Does that better explain my point?
