I don’t want to make this into an Amsoil bashing thread, but I take issue with some of their business practices and marketing and this is a good forum to discuss it. So for the Amsoil reps, to bad, it’s being discussed.
We know Amsoil meets the ZDP level required to meet the API SN specification. This was just confirmed by PQIA’s analysis. Why doesn’t Amsoil certify their SS line? Base oil interchange is a lame excuse. There are many interchange options available for suppliers of PAO and Grp III base oils. That makes no sense to me.
Certification costs are low, and many other small blenders pay them to approve their oils. What is Amsoil’s excuse? Why does everyone else play by the rules with no issues, except for Amsoil? The only conclusion I come to is that Amsoil does NOT run all the required testing to really validate the performance of their oils. Unlike Mobil 1 EP, which actually MEETS GF-5/SN, Amsoil does not and there must be a reason.
Recently on another forum, a retired CVX tribologist claimed Amsoil 5w40 Euro does not pass some of the required testing. He claims they tested it and it failed. I can’t confirm how true this is, but I found it interesting.
When you reference specifications that your product meets, but use words like “Recommended for” or “Meets or Exceeds” and do not actually test it, then it’s kind of deceptive.
