I wasn't aware llamas retracted the article but I can imagine why. He was clearly confused about some of the data and the subtleties of the SAE and ISO viscosity grading systems.
Despite clear and concise specifications for mild EP gear oil in the Ford N-series Owner's Manuals the SMO 90 / GL1 myth will not die.
It's too bad Ford never provided publicly available data sheets for their lubricants. I had to call the company that made the 134D product to get even basic properties.
