Stumpy,
I was just giving you a bad time. I was just pointing out that age has very little to with the worthiness of a man or technical information. Sure the information is dated, but so are the parts and problems that are being discussed.

If you had read the SB you would have seen that it addressed problems that were encounter in the field and some fixes. The second paragraph has a statement that a special additive was not required and when used, only temporarily resolved some of the symptoms. It did not fix the problem.
