Where you drive, in my opinion, no.

Your engine would not run rust free for 23 YEARS and suddenly form rust out of the blue without good reason. Mr. Wesenberg explained it exactly. Rust had formed and settled in the back years ago when people were running straight water in your engine and it finally broke loose. Rust will not form in a proper ratio mix of soluble oil and water. In your case the rust was already there and mixed in when it came loose.

On the other hand, an oil/water mixture that is too weak can form rust just as a weak mixture of antifreeze to water can form rust. Seen it all my life.

I take exception to your second last sentence. What proof do you have to support this allegation? I believe it is merely a suggestion used to support the decision for not spending money. Wayne
