  • More discussion of motor oil

    I know this has been beaten to death, but here is a little article about the subject from "Machinery Lubrication" magazine.

    It is a pretty good read, even if generic and dated..
    For a guy employed by an oil company, he did a good job keeping the marketing hype out of the article.
    One of the better layman explanations of cold pour point changes made within the industry and how to look around them.
    Thanks for sharing the link. This is a decent one!

      Interesting.

      Here is something similar but about ZDDP...

      Oil Myths

      The summary is this...

      "Those who hold onto the myth are ignoring the fact that the new Starburst oils contain about the same percentage of ZDP as the oils that solved the camshaft scuffing and wear issues back in the 1950s. (True, they do contain less ZDP than the oils that solved the oil thickening issues in the 1960s, but that's because they now contain high levels of ashless antioxidants not commercially available in the 1960s.)
      Despite the pains taken in developing special flat-tappet camshaft wear tests that these new oils must pass and the fact that the ZDP level of these new oils is comparable to the level found necessary to protect flat-tappet camshafts in the past, there will still be those who want to believe the myth that new oils will wear out older engines.
      Like other myths before it, history teaches us that it will probably take 60 or 70 years for this one to die also."

        Reading that whole thread left me just as uncertain as before I read it.
